Starting point is 00:00:00 Hello everyone! Today I'm speaking with Physician Bongevity Expert and now author Dr. Peter Adia. We discuss his new book Outlive, The Science and Art of Longevity, and explore the immense benefits that can be gained from exercise in just three hours a week. How small imbalances in diet can cause major problems such as diabetes and obesity, the difference between lifespan and health span, the sourd reasoning behind the American food pyramid and the scientific side of alternative diets No buzzwords Looking forward to the discussion today Dr. Adia in your book you talk about
Starting point is 00:00:56 lifespan in general, but you also concentrate on a concept called health span termed health span and a called health span, termed health span, and you're concentrating more on decades, let's say, of healthy life, rather than absolute length of life. Do you wanna expand on the concept of health span and why you distinguish between that and longevity per se?
Starting point is 00:01:17 Yeah, longevity is really a function of lifespan and health span. So life span is the easier of those two to understand because it's binary, you're either alive or you're dead. And I think when most people think of longevity, they think of the elongation of life span understandably. But, you know, that's really only part of it. The other part, the part that might actually be more important to most people when pressed on the issue is health span, which is the quality of life. And the medical definition of health span
Starting point is 00:01:47 is not a particularly helpful definition in my view. It's effectively the period of time from which you are free of disability and disease. But I don't really think that captures what health span is to most people. And so I think health span is a broader concept. And it's not binary, it is analog, but it really constitutes some measure of cognitive health, physical health, and emotional health.
Starting point is 00:02:10 And at least two of those are intimately linked to age, which is to say they generally decline with age. But if we focus, I think, relentlessly on the pursuit of those things, we tend to get a better quality of life overall. And by the way, you think you get for free a lot of lifespan benefits. Right. So, well, it's very important to get the definitions and the measurements right, because systems optimize to maximize their score on what they're measured by. And I suppose living to 140 wouldn't be so good if you were senile for the last 70 years
Starting point is 00:02:45 an institutionalized for example. And so it sounds like when you talk about health span, you're intermingling to what would you say to quality of life issues. One would be the expansion of youth rather than longevity per se. And then something associated with the existential quality of life. So maybe we could start with, well, does that seem to capture the interaction of those two things seem to capture what you're talking about with regard to health span? Yeah, I think so. I think that the cognitive and physical piece are the pieces that do decline with age, and we want to preserve
Starting point is 00:03:26 those as long as possible. We can be very specific about what those things are, by the way. We could drill into what is cognitive health span, what is physical health span, and then that other one that is not so age dependent might be at least as important, and probably frankly falls much more into your wheelhouse than mine, professionally at least, and that is about the quality of a person's life, and the quality of their relationships,
Starting point is 00:03:52 their sense of purpose, and things of that nature.

Yeah, so a long while back, I was looking at interventions to improve people's lives. And I knew at that point that cognitive decline was a major problem, especially in terms
Starting point is 00:05:19 of productivity and general competence. So it's pretty pronounced linear downhill trend on the fluid intelligence front from about the age of 25 forward. And that can decline precipitously in, say, late 70s, early 80s, especially with the onset of degenerative neurological diseases. And I was looking at the literature on cognitive remediation. This is back in the times, about 10, 15 years ago, when there were a lot of online sites that purported to run you through cognitive exercises that could increase or maintain your IQ. There's never been any evidence for that, by the way. It's a pretty damned
Starting point is 00:05:58 dismal literature. But I, what I did find, and I think this is extremely solid, is that if you want to maintain your cognitive function, that both cardiovascular exercise and weightlifting seem to do a pretty damn good job. Maybe that's because the brain is such an oxygen demanding organ and other obviously energy, it's energy demanding and resource demanding in other ways. And if you can keep yourself cardiovascular fit, interestingly enough, that's the best pathway to cognitive health.
Starting point is 00:06:31 Then I was looking on the psychological side, and what I found was that there were interventions that help people get their story straight or psychotherapies, one of those, but there are written interventions. If people write about their past, about their past traumas, and if they write about their future plans, they reduce general uncertainty. That reduces their stress, and that seems to produce a relatively pronounced physiological
Starting point is 00:06:56 benefit. And so there's an interesting interplay there that we can talk about more in terms of the emotional and the physical. It's pretty funny that if you want to improve your cognitive function or maintain it, you should exercise rather than think. And that if you want to improve your physiology, you should straighten out your story and face your traumas rather than say exercise. So, what do you recommend in your book, you know, live in particular with regard to the expansion
Starting point is 00:07:28 of health span? What do you think, and how do you practice this personally? What do you recommend to people? So I think that exercise is empirically the most valuable tool we have for both the cognitive and physical components. So let's start with the cognitive, because I think here it was less intuitive. So about 10 years ago when I really went down this rabbit hole,
Starting point is 00:07:51 I had one of my research analysts spend a lot of time going through the literature. So we created a framework where we were going to look at every single intervention and how it impacted executive function, processing speed, short-term memory, long-term memory. Those were the four metrics we cared about, because as you point out, those are all bits of intelligence that decline with age.
Starting point is 00:08:17 So, we looked at everything. So we looked at every molecule, we looked at every possible thing that you could think of. And after about nine months of this, the thing that stood out above all else, beyond any diet, beyond the importance of sleep, and other things that certainly mattered, controlling blood pressure, lipids, et cetera, was exercise. And I, even though I was a lifelong exercise or in love to exercise, I just couldn't believe it. It seemed so trite that exercise could have such a profound difference on the state of cognition,
Starting point is 00:08:52 not just in terms of its performances, effectively a no-tropic, but also in its ability to delay, if not outright, prevent dementia. So once we dug into the mechanisms, I think it became clear why exercise is so potent. And it's basically that it is acting on so many different levels. So as you pointed out, it's acting at a metabolic level.
Starting point is 00:09:15 The brain is such an energy demanding organ. As you know, and maybe your listeners do, it weighs about 2% of your body weight, and it's responsible for 20 to 2% of your body weight, and it's responsible for 20 to 25% of your energy consumption. So therefore, anything that disrupts that is catastrophic. So when you look at the improvements in glucose, disposal, insulin sensitivity, and all metabolic parameters, exercise is the most important tool we have there. When you look at the reduction of inflammation, vascular health improvements, again exercise have there. When you look at the reduction of inflammation,
Starting point is 00:09:45 vascular health improvements, again, exercise stands alone. When you look at the production of neurotropic growth factors such as BDNF, again, exercise is basically a drug for neurons. And so I think I eventually came around after a year or so to realize that, again, as simple as it sounds, exercise is such a potent tool. And you look at the brains of people who exercise a lot, and you can see far less damage,
Starting point is 00:10:12 not just microvascularly, but in terms of brain volume loss over time. So, let's talk about exercise from the perspective of a behavioral psychologist. So, one of the things you learn as a behavioral psychologist is that it's very difficult for people to change their attitudes or their actions, and it's very difficult for people to change their lives. And so, and we all know this because we might tell ourselves, for example, to exercise. And we might be well supplied with arguments for why that's a good idea, but that doesn't necessarily mean that we learn how to incorporate an exercise routine into our life. And often the reason for that, there's many reasons, I mean, exercise is difficult, and that's one reason. But it's also often the case that
Starting point is 00:11:01 people don't form a strategy and break the problem down into steps that are simple enough to actually implement. So they think things like, well, I'll go to the gym two hours a day, three times a week, and I'll start that next week. And truth of the matter is, they don't have six hours to spend, and they can't tell themselves what to do anyways. And so what you do as a behavioral psychologist is you look at the simplest possible change that produces the maximal possible benefit.
Starting point is 00:11:28 And so for example, if people are listening and they want to begin to implement an exercise routine, like what about a daily walk of 10 minutes in the morning? Like where would you start someone? So it completely depends on their baseline. But based on your question, Jordan, I'm going to take it as we're talking about someone who's doing no exercise. Yeah, let's start with them. Yeah, so the good news is, first of all, and I accept the fact that not everybody is swayed by data, but I at least want to put it out there. So if you're a person who's in the doing zero exercise per week camp. The very good news is the benefit you get from
Starting point is 00:12:08 going from zero to three hours a week is a greater benefit than anyone gets along the exercise curve, right? So taking someone who's at five hours and taking them to 15 will produce less relative benefit than going from zero to three. So in other words, I want that person to see some real incentive for making this change. Secondly, I'll put some numbers to it, right? So going from no exercise to three hours a week, approximately reduces your cause of, your all-cause mortality,
Starting point is 00:12:41 that is to say death by every cause, by 50% at any moment in time. So if you're standing there asking, what's the probability I'm going to die this year? Well we can sort of actuarially figure that out. You get to cut that number in half by simply going from zero to three hours exercise a week if you're a non-exerciser. So again, there's going to be a subset of people for whom that's a very powerful piece of information they didn't know.
Starting point is 00:13:06 So then what I would say was how do you do that? So I agree with you that you're much better off trying to do 30 minutes, six times a week, than three hours once a day, or two hours in whatever fashion. So what I would say is the most effective way to do that is probably about 90 minutes of low intensity cardio. And for a person who's not particularly fit, that's gonna amount to just brisk walking. Rather than tell them what to do,
Starting point is 00:13:38 I tell them how to feel when they're doing it. So what you wanna feel is out of breath enough that you can barely carry out a conversation, but you could if you had to, but not so out of breath that you can't carry on a conversation, and not so easy that you can speak easily. So there's that sweet spot in there, physiologically we call that zone two,
Starting point is 00:14:01 but I'm not gonna bore them with that nomenclature. It's just basically 90 minutes, say three times 30 or two times 45 a week, where you're just out of breath enough that you don't want to talk, but you could if you had to. That's part one. Right. So you push, push yourself past your, slightly past your simple level of comfort. That's right. And so let me push on you a bit with regards to three hours a week,
Starting point is 00:14:30 again, from the perspective of taking someone from zero to to somewhere. What are the benefits, let's say? You talked about the benefits of walking something approximating 20 to 25 minutes a day. That can be dispersed out in various ways. You also mentioned like two 45-minute sessions or three 30-minute sessions. If someone, what would happen if someone goes from zero to like 10 minutes a day or an hour a week? Where do that benefits of that three hours? Yeah, that's a great question. I don't think we have the fidelity of the data at that level,
Starting point is 00:15:01 because you generally don't push enough of a conditioning benefit. But I think what you're getting at, and we do this as well, is you want to separate between the behavior change and the physiologic change. And for some people, and James Clear has written a lot about this, but I think a lot of people have come to the same conclusion with any behavior change. If it's a person who's never done anything, you're right. The answer might be for every day when you wake up in the morning, rather than your normal routine of jumping in front of the computer, I want you to go and walk around the block
Starting point is 00:15:34 once. It'll take four minutes. And so I don't want to represent you're going to get a physiologic benefit from that. You probably won't. But what you will get is you're going to start to reset a behavior, which is, aha, the first thing I do in the morning now is this other thing. And we'll slowly increase that. And at some point, you will get a physiologic benefit. But what we're doing is planting the seed of how to change the behavior. Yeah, well, you could always expand that over a year. I mean, one of the things, another thing I learned as a behavioral therapist, and this seems obvious, but it's not obvious enough so that people think about it or put it into practice is that your life is made up of the very small number of things that you repeat
Starting point is 00:16:18 every day. And these are often things that people consider trivial. So for example, lots of people sit down to have dinner with their family every evening, and they don't consider that special. But because you do it every day for an hour, an hour and a half, it's like 8% of your life. So you only have to get 15 of those things in order, and you have your whole life in order. Same thing applies to a daily habit. And so if you started, say, walking for 10 minutes a day, well, that's 70 minutes a week, and that's four hours a month, or 50 hours, or one work week a year. And that's a substantive change. That's about 2% of your
Starting point is 00:16:59 life. You're a waking life, something like that, or at least 2% of your awake working life. And so these, it's useful for everyone listening to understand that small changes that you maintain can be of radical importance. And once you're walking for 10 minutes a day, it's a hell of a lot easier to go to say 12 minutes than it is to go from zero to walking at all. So yeah. So okay, yeah. So, okay, okay. So, what do you think? What did you conclude as a consequence of going through the literature with regards to, say, weightlifting rather than cardiovascular
Starting point is 00:17:35 exercise? So, in biology, we look to integral functions to give us a sense of how valuable and input is, and you don't get many of them, okay? So most people are probably familiar with something called a hemoglobin A1c. It's a blood test you get at the doctor, and if it's high enough, it tells you if you have type 2 diabetes. So if the hemoglobin A1c is beyond 6.5%, that tells you that over the past three months your average blood glucose has been 140 milligrams per desoleter, which is the cutoff for type 2 diabetes.
Starting point is 00:18:12 So in that sense hemoglobin A1C is an integral of your behavior over the past three months with respect to glucose. We don't have a lot of those, but we have two really amazing ones with respect to exercise. One of them is around strength and muscle mass, and one of them is around peak cardio-respiratory fitness. With respect to...so I'll just get to the punchline. The punchline is, there is no metric that is more highly associated with living a long life. Just this is purely based on length of life. There's no metric anywhere in the medical literature. It's more highly correlated with this
Starting point is 00:18:52 than having a high VO2 max. VO2 max is a measure of your peak cardiovascular fitness. But the second most highly correlated metric of length of life is a composite metric of strength and muscle mass. So in other words, and why people always ask me why is it so important? I think it's important because those things are remarkable integral functions. VO2 max isn't just. You want to define integral? Oh yeah. Yeah. Yeah. So they
Starting point is 00:19:24 basically tell you they add up the work that has been done to that point. So you don't just have a VO2 max because you woke up one day and decided to do something positive. You have a high VO2 max because you've been training very hard for a long period of time, in many cases for years. Similarly, a person doesn't just wake up and have a lot of muscle mass or have a lot of great strength.
Starting point is 00:19:50 Those things are the product of a lot of work. And I think that's why they are so potent. In fact, they are far more potent as predictors of a long life than all of the negative things you can imagine are predictors of a short life. So when you look at things like smoking, type 2 diabetes, hypertension, even the presence of cancer has a lesser impact on the shortness of your life than those other variables have on the length of your life. Yeah, I've read that grip strength, for example, is a good marker of propensity for longevity
Starting point is 00:20:26 in everyone, but particularly in elderly people. And it isn't, as you pointed out, because grip strength per se is particularly important, but because grip strength happens to be a good marker for overall, what would you say, psychophysiological integrity? 100%. 100%. Yeah, grip strength is one of the most potent so put this way the if you compare the top Desi all to the bottom desi in grip strength it's a 70% difference in incidents and death from
Starting point is 00:20:53 dementia all caused dementia not just Alzheimer's every form of dementia when I was in my mid-20s when I was 21 22 I weighed about 130 pounds 135. I was six lit one. And so very, very thin. And I spent about three years, four years intensely weightlifting and packed on about 35 pounds muscle. I did like a mad dog for about three years to do that. But one of the things I noticed that was really cool was that I also got to be a lot more coordinated. I was using free weights, you know, because free weights help exercise all the little muscles and tendons. But I also, it also seemed to me to be unbelievably useful for facilitating, likely for facilitating, nerve-mile andization.
Starting point is 00:21:40 And I thought then, think now that that was probably a good marker. That increase in coordination was probably a good marker for improved neurological function. And so, and as you age, it doesn't get a lot of attention, but sarcopenia, which is the loss of muscle mass, the wasting away that occurs with aging. And again, this begins rather subtly. We lose, you know, what are called type two muscle fibers first. That's the hallmark of aging. So the type of muscle fiber that's responsible for explosive power is the first one that
Starting point is 00:22:15 begins to atrophy when we age. Even at my age, I'm 50, I'm already experiencing that to a great extent. I don't have a fraction of the explosive power I had at 25. Once you lose explosive strength, you start to lose overall strength. And once you lose that, you're gonna start to lose muscle size is the very last thing. So by the time a person is 75,
Starting point is 00:22:38 the decline in muscle size, which is already proceeding strength is significant. Now we can do a lot to prevent this, and I think that that's what's being captured by these statistics. The people who are able to delay that loss of strength and muscle mass are the ones that are going to live the longest on average. Yeah, so on the weightlifting front, we talked a little bit about what you could do simply to start working out on the cardiovascular front. And brisk walking is the simplest and most straightforwardly implementable strategy on that front.
Starting point is 00:23:15 I would add one thing to that, Jordan, which is once a person reaches a certain level of fitness, the brisk walk may not be sufficient enough to produce enough cardiovascular stress. Depends where you live, but if you live in an area where you've got a lot of hills, that might not be the case. But for most people, you know, there's a limit in human gate to how fast you can walk.
Starting point is 00:23:38 And for most people, it's about 3.5 to maybe up to four miles per hour. And again, at a certain point, that's not gonna be fast enough. So what we can do for that individual, rather than have them transition to running, I like to put weight on their back, called rucking. So you carry a military type of backpack with plates of weight in the back, and now you, without putting additional stress
Starting point is 00:24:00 on the knees, put additional stress on the cardio respiratory system. So just throw that out there, is additional ways to get this done. putting additional stress on the knees, put additional stress on the cardio respiratory system. So just throw that out there, is additional ways to get this done. Yeah, well, okay, okay. As I said, in my 20s, I worked out with free weights and I have an adjust set of adjustable free weights now,
Starting point is 00:24:17 but what I found very straightforward and actually implementable is to use, I use about 20, 25 pound weights, depending on how often I'm doing it. And run through, I run through a set of exercises through my whole body, starting with my calves and moving upward. And I can do a whole workout routine,
Starting point is 00:24:36 both two sets of 15 exercises in about 20 minutes. And so for everyone listening, it's also very simple to use to start weight lifting because all you need is a couple of dumbbells. Size is going to depend on, you know, your size and your strength. But you can do an awful lot with with two dumbbells. You can exercise your body in all sorts of ways. So that combined with walking and well and you had another twist to that. That's not a bad initiation. Anything out on the weightlifting front?
Starting point is 00:25:07 Yeah, I think the other thing that I would say, and I think about this stuff all the time, so I have a very elaborate gym I do, you know, every sort of exercise you can imagine. But sometimes I like thinking and debating with people like, what's the single most important exercise you could do if you could only do one? And for the lower body, I think step ups would be, so if you had just two dumbbells and a box, you can do anything, right? Because you're going to do forward step up, backward step up, side step up, you can go heavy, you can go light, you focus on the concentric phase, which is the phase of getting up.
Starting point is 00:25:43 Concentric is the phase of a muscle when it's getting shorter, but then you really get to focus on how slowly you can step down. So my typical, I'm doing box stepups at least twice a week. I do a count of one up, three down. So taking three full seconds on that one leg to descend, and that's training what we think of as the brakes. So when we age, this is a particular form of strength
Starting point is 00:26:07 that deteriorates, which is eccentric strength. The strength that a muscle exhibits while it is getting longer. This is why so many old people fall. And the mortality of a fall when you are above the age of 65 is staggering. So depending on the series you look at, 15 to 30% of people above the age of 65 is staggering. So depending on the series you look at, 15 to 30% of people over the age of 65 who fall and break a hip will be dead within a year of that fall. Of those who survive, 50% of them will experience a reduction in class of mobility. So, meaning people who walked normally will walk with a cane, people who walked with a cane, will walk with a walker, people who walked with a walker will be a wheelchair bound.
Starting point is 00:26:48 This is a profound change in quality of life, and a lot of it has to do with a loss of this type of strength. If you think about it, people are much more likely to hurt themselves stepping off a curb when they get old than stepping onto a curb. It's these loss of breaks. So, yeah, a set of dumbbells, which you can carry around, because that's really a very important piece of upper body strength is being able to carry something.
Starting point is 00:27:13 That's where that grip strength is coming from. And being able to do step-ups, step-downs, squats, all sorts of things. Yeah, you don't want to let perfect be the enemy of good when it comes to initiating this type of thing How how how high does the box work can use steps? Yeah, so I think a box is superior What you want to be able to do is work up to a height such that when the foot is on the box the front leg is on the box The thigh is parallel to the ground. So for most people, that's 16 inches, maybe 18 inches,
Starting point is 00:27:50 a very tall person might be 20 inches. I recommend people started a 12 inch step until they, you know, sort of, and you start with your body weight. Let's be clear. I mean, for many people just doing a proper step up and step down with body weight at 12 inches is right. And actually, in the book, it was becoming so difficult to write about this in detail
Starting point is 00:28:13 that I did. There's a whole section where I write about how to do this. But in the end, we created a thing on our website where I just have a bunch of videos where I illustrate these things. So in the book, it directs people to where to go to just see, I think eight or nine videos of the most important exercises that I think people should be able to do. Well, we should put that in the video description, so we'll have to remember to do that, yeah. All right, let's say, if you don't mind to nutrition and diet, and we can talk about obesity,
Starting point is 00:28:42 diabetes, and inflammation on that front. I was interested in your comments on diabetes. So my understanding, and this is entangled with the problem of obesity, my understanding is that when physicians test for blood sugar, they age adjust the norms, and that strikes me as, let's say, peculiar, because it seems self-evident that if you have normal levels of blood sugar at 40, but that would make you diabetic or prediabetic at 20, then you're actually diabetic or prediabetic. And what that implies is that the rate of diabetes, which is already ridiculously and preposterously,
Starting point is 00:29:29 devastatingly high, is actually much higher than we think. So correct me if I'm wrong or elaborate on that, if you would, if you think I'm onto something there. So we don't do that. I can't speak to what any other physician does, but in our practice, we hold everybody to the same standard. I think we will acknowledge on one metric because we use a standardized dose of glucose when
Starting point is 00:29:56 we do what's called an oral glucose tolerance test. We will give women a little bit more latitude because they don't have as much muscle mass. So there's a particular test that we do where we give people 75 grams of glucose and we time at 30, 60, 90, on 120 minutes what their glucose and insulin level is. And in that window of time, what you are testing is how efficiently do their muscles take up glucose.
Starting point is 00:30:22 That's called glucose disposal. So you're measuring insulin's called glucose disposal. So you're measuring insulin sensitivity and glucose disposal. And in that window of time, that's the only place you can put the excess glucose. And because women have less muscle than men, we will tolerate a slightly higher glucose response, but we want the same insulin response. So that's, and it's a very subtle difference. but we want the same insulin response. So that's, and it's a very subtle difference. But no, we don't age adjust for anybody. We sort of, we want a 60 year old
Starting point is 00:30:51 to be as effective at this as a 30 year old. So can you outline for people what happens during normal Western aging, let's say on insulin and glucose metabolism front and what that implies for age-related degenerative diseases. It's a very interesting thing and we're not entirely clear why, but there is an unmistakable decline in insulin sensitivity as a person ages. Now, it doesn't mean that you're destined to have insulin
Starting point is 00:31:26 resistance or fatty liver disease or type 2 diabetes when you age, but what it generally means is on average a person needs to be more diligent as they age. And I've heard lots of theories offered for this and my guess is they all play a role. There's clearly a reduction in testosterone as we age. Testosterone is a very pro metabolic health hormone, right? So testosterone promotes lipolysis of fat by muscle. It promotes insulin sensitivity. In fact, there was a clinical trial
Starting point is 00:31:59 about a year and a half ago that looked at men without type two diabetes, but who were pre-diabetic on and off testosterone replacement therapy, and you showed a significant reduction in the progression to type 2 diabetes in men on testosterone. So clearly the decline of testosterone is playing a role in both men and women, by the way. We also see less expression or less activity of an enzyme called lipoprotein lipase, LPL, where it shifts more of its activity from muscle to fat. This is, again, an enzyme that is responsible for the breakdown of fat.
Starting point is 00:32:40 There are also other things, as you pointed out, such as inflammation that increases with aging. We also tend to be less active as we age, and one of the most important things to preserve insulin sensitivity is activity. So there's a really famous researcher at Yale named Jerry Schulman, who is one of the world's authorities on the ideology of insulin resistance. And when he does clinical trials, when he does experiments on human subjects at Yale, and he wants to study insulin resistance, the one criteria he must have is that the subjects can't be physically active.
Starting point is 00:33:20 So in other words, for him to figure out what insulin resistance looks like even in a 20-year-old, he has to ensure that they are not exercising at all. So, it's some combination of these things and probably some other things that are explaining why all of us have to work harder as we age to avoid this phenotype. So, maybe you could define insulin resistance, describe its relationship to elevated blood sugar or to blood sugar in general, and then discuss the relationship between elevated blood sugar, insulin resistance, and aging as such. So think of the muscle maybe as a balloon and the balloon is the only place where you can put air in this analogy air is the glucose. So there are some balloons that are very easy to blow up and you know you can put the
Starting point is 00:34:21 glucose into the muscle cell you can put the air into the balloon quite easily. You don't have to blow very hard. But imagine a balloon that's very, very difficult to put air into. And at some point, you can get air into it, but you have to blow much harder. So how hard you have to blow is the amount of insulin you need to put the glucose into the muscle.
Starting point is 00:34:45 At some point, you will not be able to do that. You can't blow hard enough. So again, just thinking about this in terms of physiology, glucose is a molecule that needs to be regulated very carefully in our bodies. Too much and too little is catastrophic. And so the body does a great job of trying to take excess glucose out of the circulation and put it into muscle cells.
Starting point is 00:35:09 By the way, just to put this in context, Jordan, a healthy person has about one teaspoon of glucose floating around all of their circulation at any moment in time. A person with one teaspoon, a person with frank diabetes has two teaspoons. That's the difference between healthy and nearly dying, right? It's profound. And how many teaspoons of sugar are in a bottle of coke? It's 30, I think, or 35. About eight.
Starting point is 00:35:39 About eight teaspoons in a small bottle. I guess I was thinking of a big, I was thinking of two. In a big two liter, and a big two liter would probably be about that. Yeah. Right. So, our body is amazing at doing this, but it's a very delicate dance between how much insulin
Starting point is 00:35:53 do you need to make that happen? And the, the, the canary and the coal mine of insulin resistance is after a person is challenged with glucose. Even if their glucose levels normalize, they needed supernormal levels of insulin to do it. That's the initial blowing too hard on the balloon. So, when you develop insulin resistance and that progresses to diabetes, you literally can't produce enough insulin to get sugar into the muscles. That's correct.
Starting point is 00:36:24 Eventually, you cannot make enough insulin. And this is complicated by another factor, which ties into this cascade of metabolic disease, which is eventually fat starts spilling out from the cells that we are meant to use to store excess energy, which are our actual subcutaneous fat cells. And that fat starts spilling into other areas where we're not supposed to have it, into the muscle, which is what's causing the actual mechanism of insulin resistance. It's the fat in the muscle that is preventing the insulin signal from being heard effectively by the muscle cell.
Starting point is 00:37:02 It also expands into the liver. That's what's called fatty liver disease or non-alcoholic fatty liver disease. The fat starts to be deposited in the pancreas where insulin is made, and that creates an inflammatory environment to the insulin-producing cells. So now you have the double whammy. You need more insulin, but you can make less of it because of the inflammation. And this thing very quickly spirals out of control. And the end state is type two diabetes. So, now you have two teaspoons of sugar in your blood instead of one teaspoon. And so, what are the consequences of that excess sugar load, which in absolute amount seems very trivial, right? I mean, one teaspoon in all of your blood
Starting point is 00:37:46 seems like almost nothing and two doesn't seem like much either, but the difference is at two teaspoons, the difference is starting to tip you towards towards what sort of... So you have two problems going on now. You have too much glucose and too much insulin, because remember, when you have that high level of glucose, you're going to be treated with drugs that aim to increase insulin. And that can sometimes be insulin itself or it could be drugs that produce more insulin.
Starting point is 00:38:16 So let's start with the glucose side of the equation. The easiest way I think to think about this is too much glucose is bad for small blood vessels. Too much glucose is bad for small blood vessels. Too much insulin is bad for large blood vessels. So what are those small blood vessels? The very first place this shows up is looking right into the eye. So I've always believed that a good ophthalmologist will spot metabolic disease before any doctor will.
Starting point is 00:38:43 Because when they can look into the retinal artery and see the earliest indication of microvascular occlusion and inflammation, that is tied directly to what's called the glycosylation. So glucose sticking to proteins, including hemoglobin in the blood, that's basically creating microscopic, what we call ischemia, or lack of blood flow to the most distal, perfused organs. So other small vessels that are absolutely ravaged by glucose are the kidneys. So diabetes, along with hypertension, would be the most common driver of end-stage kidney disease.
Starting point is 00:39:21 You also see it in the coronary arteries. And believe it or not, it's probably one of the most important physiologic drivers of erectile dysfunction. Again, very small blood vessels in the penis, and therefore, when these things succumb to this type of end-stage glycosylation, you're going to see damage all around. Conversely, on the insulin side, elevated levels of insulin chronically, it's a pro-growth factor, so it's very likely the explanation for why obesity
Starting point is 00:39:51 is the second leading environmental contributor to cancer after smoking. And it also damages large and medium-sized blood vessels like the aorta, the carotid arteries, et cetera. So this cascade of, again, it doesn't sound like much of a difference, as you said, it's a chronic issue that over enough time leads to the destruction of most issues. So can you lay out the relationship now between insulin resistance, excess blood sugar, and the propagation of fat tissue.
Starting point is 00:40:27 Now, the fat is being used to store energy, but how does that actually occur and how is that related to excess sugar? Yeah, so in many ways, we were doing really well as a species until, you know, 100 years ago, right? In that, what allowed us to have this remarkable escape from all other species, vis-a-vis natural selection, was this ability to store energy and fuel our brains? So as we talked about earlier, like the brain is such an energy demanding organ that we couldn't have survived if we didn't have a way to keep energy portable with us.
Starting point is 00:41:09 How would we survive a day with no food if we didn't have a way to store energy? Certainly more than one day, you have to use fat stores to get by. You can't just rely on glucose stores. We have this very efficient way to do it. We have a very safe depot of subcutaneous fat where we can put fat in it, which is excess energy, and that's primarily fatty acids, and also excess glucose can be stored in this form. And we can acquire it as we need it, right? So, you know, when energy stores are low, you go and you get that, or when energy itself is low, you go and acquire this. The problem comes when you exceed the capacity of that.
Starting point is 00:41:52 So, the way I describe it in the book is, everybody, and this is largely determined genetically, everybody has a bathtub. Some people have a really big bathtub, some people have a really little bathtub. The bathtub is the total capacity of your fat, your fat cells to store fat. So water goes into the fat cell, that's the food you're eating. There's a little drain at the bottom which is all the energy you're expending, that's coming out.
Starting point is 00:42:18 And therefore, the energy in, less the energy out determines the balance of water in the tub. Then less the energy out determines the balance of water in the tub. If you're getting fatter, the water is rising in the bathtub. At some point, the water gets to the lip of the tub. You have now exceeded your capacity for safe storage of fat, or in this case safe storage of water. What happens next is the water spills over. Now it's gone from being totally physiologically normal to total chaos. Just as if water spilled over your bathtub, it would be total chaos, right?
Starting point is 00:42:52 It would ruin your house. And the question is, where does that fat go once it spills over? And it's where it goes that causes all of the problems we're talking about. When it goes into the muscle, it impairs the muscle's ability to sense insulin and create the glucose transportor to bring in glucose. That's the synchwanon of insulin resistance. When it goes into the liver, it creates inflammation, which can ultimately lead to cirrhosis and liver failure.
Starting point is 00:43:21 When it goes into the pancreas, it secretes cytokines that impair the beta cells, which produce insulin, which exacerbates the insulin resistance problem. When it surrounds your organs, as what we call visceral fat, it releases inflammatory cytokines that lead to cardiovascular disease disproportionately. So again, all of these things are happening, not because we're getting fatter in the right place, i.e. water in the bathtub, but because we're getting fatter in the wrong place. And this is another example of which it doesn't take a lot of fat to spill over. If a person has 20 kilograms of fat in their fat cells, it causes no issue.
Starting point is 00:44:06 It's the two kilos that have spilled out into all those other organs that are driving all the damage. Yeah, and I read too. This is another example of the dangers and sometimes benefits of the things that you repeat every day. I read at some point a while back that the obesity epidemic such as it is could be regarded as being caused by the additional consumption of one soft drink a day, non-diet soft drink obviously. Because of course, there's a lot of sugar, eight teaspoons,
Starting point is 00:44:40 which is four times as much as you have in your blood if you're diabetic, but you're doing it every day. Now, and so that is hard on the systems that use insulin to process sugar, but it also puts this demand on your body to deal with the excess glucose. How is that glucose converted to or stored in fat? What's that mechanism? So, it's called the technical name is, is, is a, de novo like pogenesis, like pogenesis, making fat de novo from scratch. So the liver can turn, the liver is a amazing organ, by the way.
Starting point is 00:45:15 It's just if we're going to give a shout out to any organ in the body, it might have to be the liver. It's just an unsung hero. It doesn't get the attention and deserves to put just to go back to one other thing. This whole teaspoon of glucose in your bloodstream, if that number gets to half a teaspoon, you'll die. Your brain won't have enough glucose. But yet you're churning through that at a rate of a teaspoon every couple of minutes. What's responsible for that titration, the liver?
Starting point is 00:45:43 Never stops, right? So one of the other things that the liver does miraculously is it has the ability to turn fat into glucose. It has, pardon me, it has the ability to turn glucose into fat and it has the ability to turn protein into glucose. So it can also change the orientation of molecules. And so the process of turning glucose into fat is basically an exercise in breaking glucose, which is a six carbon molecule down into two carbon chunks and then joining
Starting point is 00:46:11 them in a long fatty acid chain. We would much rather store energy in fat. It's the most efficient chemical molecule in which to store energy. All the energy, of course, in our body, is in the form of chemical energy. Stored in the bonds, carbon to carbon and carbon to hydrogen. And a fat is the most efficient vehicle to do that. So we would much rather actually store energy as fat than in glucose. And we don't store that much as glucose.
Starting point is 00:46:43 Okay, so let me step sideways here for a moment. I'd like to talk about the food pyramid with you. And so I'm going to lay a little bit out about my understanding of the food pyramid and how it came about. And then we could talk about the standard western diet and its relationship to insulin resistance and obesity. So my understanding is that the food pyramid was actually produced by, not by scientists or by MDs, although there were some MDs who were consulting, who were mostly ignored, but by the Department of Agriculture. And it was a marketing scheme, essentially, and that the consequence of the marketing scheme was that people were enticed and convinced to rely primarily on carbohydrates for their nutritional necessities. and perhaps carbohydrates at far too excess at a level. Now carbohydrates are transmuted into glucose during metabolism and we eat way more carbohydrates that we need
Starting point is 00:47:53 to produce the amount of glucose that we need. Now people have been getting fatter in a catastrophic way for about four or five decades and that's really in no small parts since the introduction of the food pyramid. Now I do understand that part of the reason the Department of Agriculture did this was because carbohydrates, and this was particularly true of corn syrup, do provide a very inexpensive source of calories.
Starting point is 00:48:16 And if you're dirt poor and you don't have enough to eat, I mean, just getting enough calories, period is a vital importance. Not everybody can afford steak, for example, or more expensive foods of that type, but virtually everyone poor and odd in the West can afford basic carbohydrates. But now we're in this, but having said that, I also have red, and I think it's valid, that there was early evidence that this heavy carbohydrate loaded diet that was being prescribed was going to increase obesity and diabetes, which is done at a level that makes the pandemic epidemic look like absolutely nothing.
Starting point is 00:48:52 And this is still being pushed forward by people who are hypothetically on the nutritional front. So two questions. What's your understanding of the derivation of the food pyramid? And what do you think about its recommendations for the typical diet? So I think before getting to that, there's a broader point I want to touch on that you just sort of alluded to, which is what is the system optimizing for? So in the book I talk about the standard American diet, which I forever abbreviate is the sad. And the standard American diet is effectively, whether without food pyramid. The standard American diet is what is killing people.
Starting point is 00:49:33 And so the question is, where did the standard American diet come from? The standard American diet was nothing more than the solution to a business problem. So the business problem was we need something where we can produce lots of food. So you had to have this quantity issue, right? So that gets to part of the problem, right? We have too many people at the time who are under-nourished. We can't have that anymore.
Starting point is 00:49:59 Everyone needs to be adequately nourished. So we need scale. The next thing is exactly your point. It can't cost too much. So we have to be able toished. So we need scale. The next thing is exactly your point. It can't cost too much. So we have to be able to do it at scale and it has to be cheap. The third question or problem statement was,
Starting point is 00:50:15 it has to be non-perishable and portable, right? So you can't have abundant food if it needs to be consumed 10 minutes after it's made. So it has to be sort of non-perishable. The third, sorry, the fourth and final parameter, I guess, there would be, it has to taste really good. We have to make food very palatable. This, again, it's just part of a business and marketing strategy. And what I argue, I guess, is that the solution to those four things is what we have today.
Starting point is 00:50:47 Like when you walk through a grocery store, all you're looking at is the solution space to a problem statement called those four questions, and it's called the Standard American Diet. Now, whether without a pyramid, I'm going to just argue that 95% of people, if they go through life eating the standard American diet with no attention to how much of it they eat or maybe certain things in it that they shouldn't eat, are going to be unhealthy. There just aren't that many people that have the genes to avoid the deleterious consequences of the standard American diet left unchecked.
Starting point is 00:51:27 And therefore, what, yeah. Well, so that was the least conspiratorial account of the origin of the American. Well, I mean, I've heard and that's fine. I mean, that's perfectly appropriate. I mean, I do think that we could give the devil as do and say the consequences that we have today of this epidemic of obesity was in fact the consequence of solving a problem too effectively. I mean, the middle of supermarkets, the outside edges of supermarkets don't contain generally highly processed carbohydrates, let's say, but the center does, and they are cheap and they are delicious and they are easily provided and they are easily provided, and they are portable.
Starting point is 00:52:06 And they are, and so that did solve the problem of under-nutrition on the pure caloric front. So we're victims of our own success in that sense. And I suppose it's perfectly reasonable to dispense with the accusations that the food pyramid was nothing but a marketing scheme because it did have to solve these four problems that you described and did so.
Starting point is 00:52:29 Yeah, I mean, I think what I want, I certainly don't want to give the food industry a pass. I mean, we can certainly delve into that, which is to say, there's no question that data have been suppressed, right? There's no question that we're not having an honest discussion about the following. So are all calories created equal from an energy balance standpoint?
Starting point is 00:52:51 Sure. At an isocaloric level, if I give you 1,000 calories of Coca-Cola versus 1,000 calories of baked potatoes versus 1,000 calories of steak, it will have the same impact on your energy balance. But it won't have the same impact on your appetite and your ability to subsequently eat. I mean, to me, that's the most, I think, probably offensive aspect of where the food industry has failed, right?
Starting point is 00:53:20 So the food industry didn't set out to kill people any more than the tobacco industry did. Where these people are effectively liable is in that they're not honest about the discussion until it becomes too late. And the reality of it is junk food, I think hijacks your normal appetite centers. And I know people who are very good at working within those confines. So I know people who can eat junk food in small amounts and continue to eat nutritious food and stay in overall energy balance. They can track their calories perfectly and they can have a couple of
Starting point is 00:54:02 Oreos and some ice cream here and there and drink drink your soda here and there, and they're all fine. What I can just tell you clinically, taking care of actual people who are not robots, on average, more people than not struggle with that, and with the introduction of these very hyper-palatable foods that kind of hijack your appetite, it tends to produce overeating. And ultimately, that's the problem at hand here. When people overeat from whichever part of the pyramid they're going to overeat from, we're going to get down that whole cascade we just spoke about. It just so happens that I think the things at the bottom of the pyramid are the things that are making it easier for you
Starting point is 00:54:47 to be disconnected from the true driver of appetite. And there are lots of hypotheses here, right? There are some hypotheses that we are kind of hardwired to get a certain amount of nutrient value. And as the nutrient value of our food deteriorates, we have to eat more food. We have to eat more calories to get the certain nutrient density. There are people who argue we're hardwired to get a certain amount of protein. And as we're deluding protein content in food, we're eating more calories to get food. In other words, and by the way, I don't
Starting point is 00:55:21 think any one of these particularly is necessarily the explanation. My guess is it could be a lot of the above, but it's probably the case that we are opportunistic omnivores, right? We grew up, we evolved, eating pretty much anything we could, but we didn't eat that much of it because we didn't really have that much of it and we were wildly active. When you eliminate those two consequences, being opportunistic omnivores is not working for most of us. We have to be more selective to push back against the amazing success of our civilization. Yeah, well, it is a remarkable thing that you can walk into your local Starbucks and there's one on every corner and get an
Starting point is 00:56:05 850 calorie muffin for essentially nothing and that it is delicious and that it is addictive. And it is a hallmark of a certain kind of success. I'm going to go sideways here for a minute because I have something I suppose that's slightly more on the personal side to ask you about. So as you may or may not know, my daughter was very ill with a plethora of immunological problems, including very serious juvenile arthritis. And that was, it just about killed her. It did destroy two of her joints, and she had another 38 that were affected. And so she was always in a lot of pain. And we, I looked into the role the diet played in arthritis
Starting point is 00:56:46 through the scientific literature for a couple of years and found two things and they were somewhat contradictory. And one was that there was no real evidence that any specific elements of diet had been linked to juvenile arthritis specifically. But, and this was a major but, if people who are arthritic fasted completely, then there are three different symptoms often disappeared. And so I thought that had something to do with the consequences of fasting, but then my daughter started to play and my wife as well, very intensely with the diet, we went to a nutritionist
Starting point is 00:57:25 who recommended elimination diet at one point because we did notice that she would react to strawberries and oranges. And within a day, her thumbs would swell or her toes would swell. It's, we knew there was something she was eating. We had her tested for immunological reaction to food, but when we tested her, she showed a hyperreaction to virtually everything they tested her for. And we concluded at that point, well, there's no damn way she could be reacting to everything she's eating. Well, she went on this elimination diet and showed a bit of reduction in symptom, but the elimination diet made no sense.
Starting point is 00:58:00 Like, there was no rhyme or reason to what you could eat and what you couldn't eat. And so she started to experiment with more restricted diets and eventually settled on discovered that if she only ate beef and it turns out for her, it has to be beef that isn't aged, then all of her immunological symptoms disappeared. And then my wife and I started playing with that diet. And so I've only been eating meat for beef, fundamentally, for almost five years now. And I've talked to hundreds of people, and we've had messages from thousands of people showing that this is first of all radically effective as a weight loss strategy, and also seems to produce remarkable effects on the
Starting point is 00:58:48 to produce remarkable effects on the general disease symptom front. Back in November of 2021, there was a study published by a Harvard group, which wasn't a perfect study because it was retrospective self-report, but they followed 24, 2500 people who had been on a carnivore diet for six months and showed something approximating a 90% reduction in all disease symptoms. And it was the only scientific paper I ever read where the surprise of the researchers was palpable between the lines in the scientific writing. Because you know, in a scientific article, all that emotion negative or positive is pretty much ironed out.
Starting point is 00:59:24 But these people were so shocked by what they found that it couldn't help leaking into the document. And so while this has been quite surprising to me because I never imagined in my wildest dreams, number one, that you could just live on meat, number, and number two, that it would have such a salutary effect. So for me, have such a salutary effect. So for me, I lost 52 pounds in seven months. I went from 212 pounds to 165, which is exactly what I weighed when I was 23. And I've maintained that weight since.
Starting point is 00:59:55 I can put on muscle mass with no problem, even though I'm 62. I had a host of inflammatory conditions, some of which were quite serious, including peripheral UVitis, which sometimes blinds people in my right eye, and it disappeared completely, along with psoriasis and gastric reflux disorder, and interestingly enough, um, gum disease, which is technically incurable, which is linked to cardiovascular degeneration, and which has
Starting point is 01:00:21 gone away 100% in my case according to multiple measures that my dentists have taken. And so when I've talked to many people who've lost like a hundred pounds in a year, you know, because they come to my talks and who are just beside themselves, so to speak, as a consequence of experimenting with this diet. So, well, so that's the story. It's very strange. I don't talk about that much because I'm not a nutritionist because I'm still shell-shocked by it, but I'll tell you,
Starting point is 01:00:50 it's something to be 60 and to have the same essential body morphology that I had when I was 23. And that had all disappeared from me in my early 50s. Yeah, you're not the first person I've heard this story from Jordan, and I have to be honest with you, I just don't know how to explain it. The weight loss, by the way, is not the harder part to explain, right? So the more restrictive any diet is, the more one loses weight on average, right? So it wouldn't surprise me if we put a person on the all potato diet if they would lose weight.
Starting point is 01:01:24 Whereas if you put somebody on the no lettuce diet, nobody's going to lose an ounce. So more restrictive diets, ketogenic diets, which are not as restrictive as what you're doing, are also very effective for weight loss. By the way, so is a zero fat diet. Now it's an unpalatable diet, and I don't think it's particularly healthy diet when you sort of start restricting fat that much. The more interesting question to me is, and I can certainly understand if you would say,
Starting point is 01:01:53 I have no desire to experiment further by introducing other elements to see if I can preserve this phenotype. But the most interesting question to me is, what are the other foods out there that you might be able to consume, or in the case of your daughter, right? Like is it?
Starting point is 01:02:11 I'm obviously interested in that too, but what I have found, because I have now, and then tried to eat carbohydrates, what I have found is that if I eat any of them, I start to crave them intensely. If I don't eat them at all, they don't bother me. Assuming, and this goes to the calorie restriction issue,
Starting point is 01:02:36 one of the ways of maintaining yourself on a keto diet or a carnivore diet, let's say, is to make sure you're never hungry. And I eat a lot of meat and a lot of high fat meat, and so I'm never hungry. And I don't think that I'm calorie restricted at all because, you know, I can eat all of Tomahawk steaks sometimes in one sitting, which is about 35 ounces of meat. I never get hungry, and I eat high fat carnivore snacks too. What I found is, as long as I'm never hungry, then I, I'm not inclined to cheat. But if I do try something like an introduction of carbohydrates, first of all, some of my symptoms come back right away like the girds and I start craving like mad.
Starting point is 01:03:12 So, well, so that's why it's great. Is it all carbohydrates or, like for example, if you introduce vegetables, non-starchy vegetables, what happens? Both symptom-wise and craving wise? Yeah, well for a while I was eating nothing but meat in greens. Mm-hmm But I still had some residual symptoms My wife has a host of immunological problems that are somewhat low level and I have a different host and Michaela seemed to get all of them
Starting point is 01:03:44 and I have a different host and Michaela seemed to get all of them. And so, you know, maybe we're absurdly sensitive for reasons that wouldn't be true of other people, but it's definitely the case that I do better. And believe me, this isn't something I particularly want. It is the case that I do better if I just stick to beef. Now, could I have pork and chicken? I had a very terrible boat of ill health, and I'm disinclined to do a lot of experimentation, although I'll probably try again in the future sometime. But I do know that beef works. We've been hypothesizing internally in our family for what it's worth
Starting point is 01:04:18 is that the reason that beef works and that other rumoured animals, bison, so forth, lamb goat is because they process what they eat through so many stomachs that by the time it is actually turned into meat, there's pretty much nothing else there. So it's a very purified form of nutritional, well very purified form of food. Now, like I said, that's anecdotal. And this is partly why I don't talk about it. But I can tell you, after you've talked to a thousand people who tell you the same anecdote, you don't have an anecdote anymore. You have a hypothesis. And it's really quite something seeing these people who show me pictures of what they looked like a year ago. And, you know and they were carrying around an extra person with them,
Starting point is 01:05:06 and they're still shell-shocked by the transformation. Because it's really something to lose, say, 150 pounds in a year. And so, well, I don't know what to make of that. I do know that the diet has actually been rejuvenating for my wife and I. Its effect on muscle tone has to be seen to be believed. That's true, even though both of us are 60.
Starting point is 01:05:29 My wife is in better shape from a musculature perspective now at 63 than she was when she was 40 and she was a very physically fit person who was exercising constantly and who was in pretty damn good shape. To see that reverse rather than just stop deteriorating, I don't really know what to make of it. I would love it to be studied prospectively. I'm very curious as to what's going on, in particular with that. I mean, there are lots of data out there showing the efficacy of a ketogenic diet in the amelioration of type 2 diabetes. I do think, I mean, look, when it comes to type 2 diabetes, any amount of weight loss
Starting point is 01:06:12 is going to produce a benefit, but it seems that a ketogenic diet has the easiest compliance and there might be something to the fact that it's kind of removing the thing of which there is an excess, right? By at least taking away the thing that is in most excess, it's easier to kickstart that. A fast, of course, is also a great way to kickstart that, right? Something about taking glycogen levels down in the liver and the muscle makes this easier. Well, the advantage, too, of the diet, the carnivore diet, in particular, is because you can eat as much as you want. It's actually not a diet. The problem with diets is that they require
Starting point is 01:06:58 privation, and they require almost continual privation, and then they also tend to produce a yo-yo effect. And that's partly because if you get in a fight with your hypothalamus, which drives hunger, you're going to lose because it's there to make damn sure you don't starve, and the probability that you can overwrite it for any length of time, well, it's very, very low. And that probably varies from person to person for all sorts of reasons, but you don't want to get in a scrap with your lower level motivational systems. Now, if I ever start to crave a banana split, for example, I can just eat another five or six ounces of steak, and then I don't care. It's not like it wouldn't taste good, but it doesn't preoccupy me the way it would if I was hungry. I've really noticed this
Starting point is 01:07:41 when I go into grocery stores, because if I go into a grocery store after having consumed enough meat, then the provision of this infinite display of delicious foods really doesn't affect me much. But boy, if I ever go into a grocery store when I'm hungry, that's quite the pain in the neck because everything's delightful and tempting. So the fact that you can eat enough, or even as much as you want, on a keto or carnivore diet, does seem to distinguish it in some ways from the diets that depend more particularly on mere calorie restriction. Although I've seen the subset of people on ketogenic diets who gain weight, so they somehow are eating past their necessary, their energy point. I was on a ketogen guide for three years, actually. I used
Starting point is 01:08:27 to write about, in fact, when I started blogging in 2010, 2011, it was basically, I was mostly talking about nutrition. And for three years, minus one day, my wife's birthday, one day in that three years, I had seven pieces of dessert, but minus that one day I was in a state of ketosis for three years. And yeah, in many ways I was the poster child for it, like the efficacy in me was out of this world. What did it do for you? Oh, I mean, I lost 40 pounds. I was probably, I mean, just from a body composition standpoint, was by DexA, which is the gold standard, about seven and a half percent body fat,
Starting point is 01:09:10 every metric of every biomarker you could measure or possibly care about was in the, even by my standards, which are not to consider what's optimal, but to consider what's exceptional. Everything was great. Even things that historically people think you can't do on a ketogenic diet, like lots of intense exercise. Certainly initially, I couldn't do much of that,
Starting point is 01:09:34 but within about six months, I had regained much of my exercise ability, and by 18 months, I had certainly no discernible reduction in extreme exercise performance. Again, I don't have a counterfactual. You could argue that that's still lesser than what it would have been in an epitachinogenic night. But, you know, some people sometimes say, well, Peter, why aren't you on the ketogenic diet anymore?
Starting point is 01:09:58 Why did you stop in 2014? It largely came down to, I think, just not wanting to be restrictive anymore and wanting to kind of, you know, as my, at the time, daughter was getting a little bit older, it was, you know, sort of wanting to enjoy more of the foods that I was, was limiting. But the reality of it is, like, I don't, you know, I'm certainly not as lean as I was when I was on that diet. Yeah, yeah, yeah. Well, the other thing I noticed, this is also very cool.
Starting point is 01:10:26 And it's very important to me personally. So I noticed that as I got older, my ability to concentrate when I was reading was deteriorating. So when I was 25, 30, when if I picked up a book and read it, I would shut everything else out and I would concentrate
Starting point is 01:10:46 on focus on a tend to what I was reading, read every word and understand it with no problem. But that started to deteriorate as I got older and I noticed that it took an increasing amount of effort to shut everything off and that instead of reading as deeply as I was, I was sort of glancing at the words. And when I started this carnivore diet that reversed, and now I think, I actually think this is true. I think I can read faster and more efficiently than I could when I was in my 20s. And I was pretty good at it when I was in my 20s. And so the other thing that I've known as too is that I don't have periods of time, this was quite a
Starting point is 01:11:25 problem for me, and it might have had something to do with my immunological problems, is that I would get hypoglycemic and lose the ability to concentrate and get what do they call it, hangry, you know, hungry and angry and irritable, and that would happen several times a day, probably because I was working too much, but in any case, that is gone completely. And I really don't miss it. I wake up in the morning with a stable mood and my mood doesn't very much throughout the day. I'm also much more stressed tolerant and able to rebound back from stressors faster. And in terms of endurance, there were lots of times over the last three years when I was walking nine to 12 miles a day on a carnivore diet. I wasn't running, but my experience is that I'm stronger and I have more stamina than I did 10 years ago. That's quite something given that I'm now 62. That's a good
Starting point is 01:12:18 direction. It's one thing, like I said, it's one thing to halt the aging process, but it's another thing entirely, to see it start to reverse. And so, you know, we don't know anything about a straight carnivore diet to very little. And no one has done a prospective study. It's one that I'm actually thinking about setting up funding for if I can find researchers who are interested, because there's something there, and it was certainly established by that initial study at Harvard. So if you know anyone who's interested in doing that, you could always hook them up with me.
Starting point is 01:12:49 Sure. There are some folks to come to mind, actually. Okay. All right. So do you want to talk a little bit about the other more common diseases that you deal with in the book? You talk about heart disease. We've touched on heart disease,
Starting point is 01:13:05 you talk about cancer, neurological degeneration Alzheimer's, for example. Let's walk through that domain a little bit, if that would be okay with you. Sure, words like to start. Let's start with cancer. Everyone's favorite. Yeah, I think, you know, cancer is the second leading cause of death in the United States and globally. Of the, what I describe is these four horsemen of death, cardiovascular disease, cancer, neurodegenerative disease, and the metabolic diseases that we've already talked about. Cancer hits its peak first. So the other diseases rise monotonically with aging. Cancer actually peaks in late middle age. So cancer would be the leading cause of chronic death
Starting point is 01:13:59 or chronic diseases of aging in the 40s and 50s and 60s before it's supplanted by cardiovascular disease chronic diseases of aging in the 40s and 50s and 60s before it's supplanted by cardiovascular disease and even neurodegenerative disease. If you go back to the year I was born and you asked the question, what is the probability that a person with metastatic cancer, i.e. Cancer that has spread from its primary organ to a distant
Starting point is 01:14:27 organ. What's the probability they're going to be alive in 10 years? The answer was 0%. Nobody was going to survive that. Today, the answer is about 5%. Maybe a little bit higher, but it's really not been an enormous source of success. So let's talk about what the bright spots are. The bright spots are leukemias, lymphomas, testicular cancer. These are areas where there has been great progress, and your survival today is so much higher than it was 50 years ago. When you talk about the big killers, though, which are lung cancer, prostate
Starting point is 01:15:07 cancer, breast cancer, colon cancer, pancreatic cancer, those are the top five causes of cancer death. Median survival, the length of time you survive has increased as much as a year, if not more, but overall survival has not. This is a very important thing to understand. The risk of being dead in 10 years, if that cancer has spread, is the same as it was 50 years ago. So if all that's the bad news. Do you suppose that's a possible consequence
Starting point is 01:15:44 of the presence of cancer being a marker for a cumulative systemic failure? Is that it's, if there's cancer somewhere, is it an indicator that many things have gone wrong at many levels? And so even if you treat the cancer, the probability that that's going to be life-saving is quite low, or is it just a consequence of the tremendous capacity of metastatic cancers to spread? So there's a couple of things going on
Starting point is 01:16:13 for cancer to take place. So the first critical step of a cancer is a genetic mutation has to happen. And largely speaking, these fall into two categories. There are genes that are promoting cancer growth, and then there are genes that suppress cancer growth. So anytime you get mutations in one of those systems, it becomes oncogenic. Now fortunately, when a cell becomes cancerous, it starts to let out clues that it is not a normal cell. So when a breast cell goes from being a normal memory cell
Starting point is 01:16:58 to a cancerous memory cell, it starts to look a little bit different. And the immune system, our immune system, the cellular immune system, is very good at patrolling the body for signs of things that are not self. That's what it's programmed to do. So it's a very beautiful way to think about it. But the immune system is not programmed to recognize bad things. It's programmed to recognize bad things. It's
Starting point is 01:17:25 programmed to recognize things that are not self. This is done through something called phymex selection when we're basically very young. By the way, too much of that problem leads to auto-immunity. You can think about this through your own personal story, which is there's a very fine balance here, too much of knowing what is, you know, not self, and too little of that are both equally bad. So there are always some cells that recognize this. In fact, Steve Rosenberg, who I did my postdoc with, recently published some really amazing data, which I find one of the most staggering
Starting point is 01:18:06 statistics of all of cancer and also one of the most hopeful, which is that 80% of epithelial tumors, epithelial tumors are the ones that kill people. That's the solid organ stuff, the breast, colon, prostate, etc. 80% of those tumors produce what are called novel neoantigens, meaning they produce peptides, small proteins that are not self and are recognized by the immune system as not self. The problem is the reason those 80% of patients don't go into spontaneous remission is they can't mount a strong enough immune response to that.
Starting point is 01:18:47 So it's sort of like having some immune cells that recognize you have a virus, but not enough that they can actually kill the virus, and ultimately the virus kills them. To your broader question, which is, if you're listening to this, what do you do about it? It starts to me with, what are the two most clear environmental triggers of cancer and how do you avoid them? And then secondly, what's the rest of your strategy? So when it comes to heart disease and neurodegenerative disease and metabolic disease,
Starting point is 01:19:22 which are the other three horsemen, our ability to incorporate prevention is so significant that it plays the lion's share of our strategy. Because we have such an understanding of the risk factors for Alzheimer's disease, the risk factors for metabolic disease, and the risk factors for heart disease, your prevention strategy is not doing those 25 things, or minimizing how much you're doing those things. With cancer, there's really just two big things. Smoking and obesity slash insulin resistance.
Starting point is 01:19:56 Now, the literature would just say obesity, but I add insulin resistance because I think that the literature is too blunt a tool to tease out what's really going on. And what's really driving it, I think that the literature is too blunt a tool to tease out what's really going on. And what's really driving it, I think, is the inflammatory and metabolic IE, the high growth factors such as insulin that are coming with most, but not all cases of obesity. So what we really want to avoid is being
Starting point is 01:20:20 metabolically unhealthy and smoking. But here's the thing. So that insulin over production also, in your opinion, facilitates cancer, origination or prophyiation. Or prophyiation. I don't think it's a propagation issue, not an initiation.
Starting point is 01:20:39 Prophyiation, yep, yep. And we know that because there are more than 20 cancers whose risk, for whom your risk goes up by about a 2x factor if you're obese. And I think the only thing that makes sense in that sense, in understanding that observation, is the inflammatory and pro-growth environment that is in that individual. So do we want to avoid that? Absolutely.
Starting point is 01:21:04 But my point is, there are, think of how many people who are non-smokers who are metabolically healthy who still get cancer. That's a very long list of people. So, I wouldn't be able to hang my hat on this as, well, my anti-cancer strategy is not smoking and being metabolically healthy and hoping that that's enough. We have to have another tool in this toolkit.
Starting point is 01:21:24 And that tool is a very controversial one, but nevertheless, I think it's important, and it's very aggressive screening. And the reason for this is another observation that I don't think gets enough attention, which is when you consider two different individuals with the same cancer, but at different stages, who are treated with the exact same treatment, their survival are very different. So if you take a person with stage four colon cancer, which means the cancer has spread to, say, the liver, and you treat them with the same cocktail of drugs that you give a person at stage three cancer,
Starting point is 01:22:06 where it's just spread from the colon to the lymph nodes, but no further, at least to the naked eye. The survival for the people for whom it's spread to the liver is 0% at 10 years, whereas the ones to the lymph nodes, it's gonna be about 60 to 65% at the same period of time. A fundamental difference. They're getting the same period of time. A fundamental difference. They're getting the same treatment.
Starting point is 01:22:27 So it's the difference between treating somebody when they have a billion cells versus 100 billion or a trillion cells. And the problem is that there's more mutational burden, the more cancer you have. You have more escape mechanisms for the cancer. That's probably the best explanation for it. All of the, and we could do this analysis for all other types of cancer like breast cancer, etc.
Starting point is 01:22:51 What it points to is early detection is essential. So what does that mean practically? What do people have to do with their physicians in order to ensure that they're being optimally screened for the possibility of cancer. And at what age does that start to become more crucial? It's very difficult for me to provide a blanket statement because even when I'm talking about this with my patients, I have a long discussion with them about the challenges of doing this. So let's put aside the obvious challenge which is cost. None of the advanced types of screening, or working at the advanced rate,
Starting point is 01:23:28 are going to be covered by insurance, right? So, in the United States, it's recently been changed to 45 from 50 for the initial colonoscopy. That's an excellent step in the right direction. I still think it's about five years too late. I think even for a person without a family history of colon cancer, I would recommend, and at least for our patients, I would recommend,
Starting point is 01:23:50 screening to begin at 40 instead of 45. The frequency with which- It's not cheaper. It's not cheaper for the insurance companies to screen than it is to pay for advanced cancer treatment in hopeless cases? Oh, it certainly is, but you're confounding something, which is at least in the Canadian healthcare system that might make more sense because the government owns the risk for life. So at least if, I don't, and I can't, you know, just by the fact that I grew up in Toronto, I can't really speak to the Canadian healthcare system with any authority, but at least that something Canada has going for it, which is when you're 40, getting a colonoscopy, or when you're 50, getting a colonoscopy
Starting point is 01:24:32 that catches a little polyp that costs nothing to remove and prevent it from going to cancer, you still own that life and that risk 10 years later. In the US, that's not the case. In the US, people are never really owned from a risk perspective by one entity for very long. So there is much, much less incentive in our system, unfortunately, to truly invest in prevention.
Starting point is 01:24:59 And that's a, if we were to talk about the structural problems of the US healthcare system, that might be the single most important one. Well, the other problem on the prevention front is that prevention isn't dramatic because you get no credit for preventing 100 things that don't happen. If you cure something, that's pretty dramatic because someone's ill and you cure them and the fact that they're no longer ill is self-evident.
Starting point is 01:25:27 But if you stop something cold in its tracks, all that happens is that people pay attention to other problems and other, let's say, more showy and noticeable cures. And so it's not only hard to fund prevention, it's also hard to market it, right, because you can't give credit to the people who've managed it. And so that's a big structural problem. Like it seems, one of the logical conclusions for our conversation was that it would have been a much better investment on the government side and on the social side to have put a fair
Starting point is 01:26:01 chunk of the money that was spent on cancer treatment into prevention of the entire range of diseases that we've been discussing and with primarily with the focus likely on what, on obesity. As the number one, is it obesity? Do you think that's the number one concern across all these classes? Well, clearly. Annerative disease? Oh, yes, yes.
Starting point is 01:26:23 If you're going to say, well, it's metabolic disease, right? So obesity is just a proxy for that. But yes, metabolic disease would be the one that feeds and amplifies all the others. But there are other things that we haven't explored. Like I don't think we have done a decent job remotely of understanding, going just going back to cancer, what the impact is of other environmental toxins in cancer. And the reason I think it's so important in cancer to look at this is because smoking and obesity
Starting point is 01:26:53 only explains so much of it. So in other words, I can't tell you what the number is, but it's noable and it's large. The number of people who get cancer, who are neither smokers, nor have obesity or insulin resistance. And so there's still a big fraction of people who get cancer, who are neither smokers nor have obesity or insulin resistance. And so there's still a big fraction of people for whom something else is driving their cancer. And I suspect there are other environmental toxins, whether they be pesticides, whether they
Starting point is 01:27:18 be, you know, chemicals in the grant, like there are other things out there that might not produce a large enough signal to show up, either because of their ubiquity or because the direct impact is not as large. And the fact that we don't know this to me is problematic. Right, so that's another variant in some ways of prevention to identify additional mutagenic agents. We already know about that on that smoking front,
Starting point is 01:27:43 but, and then to take them out of the environment so that the diseases don't occur to begin with. Let's switch. By the way, I do want to say one thing about what you said, Jordan, that is very true. And there's no disease for which it's more tragic than with the de-menting diseases, specifically Alzheimer's disease. So, if wanna look at the amount of research that's gone into treatment versus prevention, it's in dollars spent, you'd need scientific notation to tell you what that that's gone into it than Alzheimer's disease.
Starting point is 01:28:30 Right. We have a couple of approved drugs. I guess, the other. Go ahead. Yeah, we have a couple of approved drugs that have virtually no efficacy. At best, they might slow the rate of progression, zero reversal. And yet, I think it's crystal clear that your trajectory towards Alzheimer's disease is probably much more malleable than your trajectory towards cancer. And we should have a very clear playbook on what that looks
Starting point is 01:28:57 like, given how difficult it is to treat that disease once it's present. Right. Well, I guess the other problem on the prevention front is that it's more difficult to monetize prevention. It's quite straightforward to monetize drugs, to cure or to not cure, as long as they're administered to enough people. But how do you monetize prevention? And people might say, well, everything can't be about money. It's like, well, without money, you can't market it. Without marketing, you can't communicate. And so there's all sorts of obstacles that are quite subtle in the way of mounting
Starting point is 01:29:29 an effective prevention campaign. And but it does, it certainly seems. If you, let's close with two questions. One might be, if you could seize control of public health spending on the research and public policy front, where would you devote the bulk of resources now? I mean, like one example might be, well, you know, would we start a campaign to reduce the consumption of carbohydrate, especially sugar, but we talked about other elements of
Starting point is 01:30:02 prevention as well. If we're going to spend our money, research money and our public health money efficiently and get the most bang for the buck, where do you think we should spend it and what evidence do you have to support that? It's really hard to say because this is just as much a behavioral question as it is
Starting point is 01:30:21 a scientific or medical question. Again, the numbers point back to exercise Jordan. There's no ambiguity about that, right? You're going to get more benefit in a person's health. If you get their VO2 max high, you put lots of muscle mass on them and you create a high degree of strength. And that's going to be true for men, women, young, old. It doesn't matter. There is no exception to this rule and therefore, you know, I would put most of my resources from a public health standpoint into how do you do that? How do you make exercise something that is interwoven from preschool onward at a level that is truly efficacious.
Starting point is 01:31:05 And that's gonna not just mean getting people to exercise, it's gonna be figuring out ways to change the environment that supports being active more often, so that you're being active, and not even when you're not exercising. But it's also going to involve understanding that everybody's different. There are some people who hate exercise,
Starting point is 01:31:23 and what do you need to do to make it more enjoyable for those people? What kind of financial incentives do you put in place for people to exercise? Because I really do believe carrots can be more effective than sticks here. And simply, you know, I mean, we talk, people are sitting here talking about, you know,
Starting point is 01:31:39 universal basic income as a potential way to alleviate some of the societal problems. Well, if we're gonna be paying people, maybe paying them to exercise and providing, you know, a way for a really good incentive around this, because it's going to obviously save cost, but I think more importantly, improve the quality of a person's life. No individual cares about the cost, right? Because they're not bearing the cost. So that's the arguments around that, I don't think matter. I think the only thing that matters is,
Starting point is 01:32:09 can we have you do something that's going to improve the quality of your life? I wonder, wonder what would happen if we took kids out for a 15 minute walk every morning as part of the school curriculum made that habitual. Now it'd be good for the kids too, because they might be able to sit down and attend a bit more if they actually had a bit of exercise
Starting point is 01:32:28 before they were required to sit and do nothing for six hours. So, you know, to start building those habits of activity in youth so that they... I mean, I would get rid of chairs. I would get rid of chairs in schools. Every kid would have a standing desk. I mean, there's's sitting is just a,
Starting point is 01:32:46 it's not a particularly productive thing. In the position we do it in, right? I mean, sitting in a squatted position is fine, but the angle that we're sitting at is really, it's not conducive to great biomechanics later in life. So if you watch a child, your kids are probably too old now, but mine or not, I can see the
Starting point is 01:33:05 change in body mechanics as they go through more and more time in chairs. And it's true of adults. Right. Well, obviously what we're doing in schools is training people to be sedentary. Obviously. I mean, that might be the most fundamental impact of the education system. I read an interesting book years ago called Systemantics by a man named John Gaul, and it's a set of aphorisms about how systems work. One of the aphorisms
Starting point is 01:33:33 which I never forgot was the system does not do what its name says it does. So when you analyze the system, for example, one of the reasons I think that universities get away with charging tuition fees that are absolutely unreasonable by any standard is that you have a pretty decent chance of meeting your lifetime mate if you go to university. And so it might be that the fundamental function of universities is to aid in the process of the sort of mating. Like systems are very complex and hypothetically the education system educates kids, but what, but it's fundamental function for all we know might be turn, to turn people into sedentary and obese adults. Because we don't know, right? We're not smart enough to analyze
Starting point is 01:34:15 the behavior of these complex systems. Let's end with one final thing. We touched briefly on the issue of emotional health. And so tell me, just tell me your thoughts on that in general. What are your recommendations in outlive in your book? And how do you associate the issue of psychological and emotional health with the, well, with exercise and diet, for example, or any of the other lifestyle modification processes that we've discussed. So, I think emotional health ties into this longevity equation in many ways. So, you can
Starting point is 01:34:52 start at a very extreme end. A low enough state of emotional health can be a direct threat to your life. So, again, the most extreme, extreme example of that would be suicide. But if you walk back from suicide, we talk about parasyuicide. We talk about all the different behaviors that people engage in that are slow suicides. I can't speak to what the statistics are in Canada, but in the United States, and I suspect you know these more than I do, Jordan, if we look at three categories of deaths of despair, suicide, overdose, and alcohol-related death, so cirrhosis, things like that, the deaths of despair have been increasing at anywhere
Starting point is 01:35:34 from 10 to 20% year on year over the past four or five years. So we just, that's brutal. Yeah, so just last year was the first year that overdose took more than 100,000 lives in the United States. Yeah, well, you know, it's an open question how many people on the edge of depressive collapse were tipped over that edge by the lockdowns and the prolonged social isolation and the increase in fear, you know, up in Toronto, I still see people, and in L.A. too, it was quite noticeable I was there yesterday. I still see people cowering behind their masks, and you have to have been made pretty chronically afraid
Starting point is 01:36:15 to still be doing that, and the cost to people's health of the fear campaign that drove the lockdowns, we're gonna see that, I mean, I don't know how that's contributing to the excess deaths. I think it would be very difficult to say that those statistics I rattled off aren't impacted by COVID. So what's going to be interesting is to see how that plays out going forward. My point, of course, is that these deaths of despair are a very extreme example of how emotional health impacts longevity.
Starting point is 01:36:48 Directly. Here, it's just truncating lifespan way too soon. In fact, overdose is now the leading cause of death in the United States for people age 10 to 55. Wow. Wow. Oh, that's terrible. So. And so, so what do you see on the prevention front there?
Starting point is 01:37:09 Or do you have, well, let's go even one layer further, because I'm sure there's someone listening to this who says, well, look, that's not me. I don't drink to excess. I would never touch an illicit drug and I'm in no danger of killing myself. So that, that means emotional health is checked. And I would say no, not really,
Starting point is 01:37:24 because that's just the first layer. Let's go one layer deeper. I think the next layer is how many people, because of their relationship with themselves, are unable to self-care. If we're really going to be honest about it, how often do we engage in not what would rise to the level of quote unquote harmful behavior, but certainly things that are not in our best care, eating a little bit too much, not exercising enough, not sleeping well, you know, engaging in behaviors or failing to engage in healthy behaviors. Now, again, I see this constantly with patients where it's not that they don't know what to do. It's not that they don't know that they should exercise,
Starting point is 01:38:13 but if you really push them, they have a negative relationship with themselves that is preventing them from taking care of themselves. And I would say that the impact on length of life there and quality of life is much bigger than the deaths of despair, but it's much harder to quantify. So then I'd go even one step further and say, okay, well, you're not in category one
Starting point is 01:38:39 where you're an immediate threat to your life because of this emotional health. And you're not even at the point where you're failing to take care of yourself. But now you maybe land where you're, you're not happy. Your relationships suck, right? You're a, you're a lousy father. You're a lousy husband. You're a lousy parent.
Starting point is 01:39:00 You know, any of these things. And you're basically living without a sense of why, right? You're not, you know, as Esther Peral put it to me, what is the purpose of living longer if you're unhappy? And I think that that's probably the biggest circle. And that's to me one of the most interesting ones here. And again, for me personally, the one I wanted to explore the most in myself, which was how much of this obsession with longevity is about figuring out how to not die versus understanding how to live. And so what have you concluded on the treatment front in regards to that set of problems?
Starting point is 01:39:46 Or the prevention front, let's say? Well, again, it's worth caveatting that everything that I write about in the book, I come to it with some lens of expertise, right? I mean, it's what I do for a living. It's what I've spent more than a decade researching. You know, I can speak with some authority about cancer and heart disease and dementia and exercise and nutrition. When it comes to this particular issue, I have no expertise.
Starting point is 01:40:12 I come at this through the lens of a patient. And therefore, I think everything I say must be taken with the understanding that it's somewhat anecdotal and therefore needs to be explored with professionals who I think can bring to it. For example, the expertise you could bring to it. But I'll tell you what I've learned. I've learned that most people probably have some degree of unresolved business in their childhood
Starting point is 01:40:43 that has produced adaptations. And in some cases, many of those adaptations are very good and should continue, but some of those adaptations are negative. And that is malleable, right? So there's this kind of this view of hope, which is you don't have to throw out the baby with the bath water.
Starting point is 01:41:03 You can, again, in my case, you can take some of those adaptations, which produce, you know, hard work, discipline, all of these things, but you can get rid of some of the negative ones, such as the negative self-talk, the perfectionism, all of these other things that created a very negative impact on myself
Starting point is 01:41:23 and those around me. So this requires very hard work, and unfortunately, it's not something that lends itself to the faint of heart. Unfortunately, at least in my experience, I'd be much more curious at your experience. Many people need to be at a local minima, not necessarily the rock bottom, but close to a rock bottom, to start to probe those. I can tell you some of the things that I've learned, partly as a consequence of public lecturing
Starting point is 01:41:56 and speaking to people constantly about how they might straighten up their life. The first thing I would say is we've run a series of studies on a set of programs I designed with my students and my my previous graduates, my graduate supervisor Robert Peel and Daniel Higgins. Peel was my supervisor and Higgins my student. We developed a suite of exercises called the self-authoring suite thereatselfauthoring.com. the past authoring program helps you write an autobiography and clear up that excess baggage. And the present authoring program helps you analyze your faults and your virtues rather programmatically so that you can start to generate a strategy to rectify your faults
Starting point is 01:42:39 and to capitalize on your virtues. And the future authoring program, which we've studied most intently, helps you develop a vision for the next five years. And if we have people do the future authoring program before they enter university, if they do 90 minutes of developing a vision, 90 minutes, that's all. No preparation with no one reviewing what they've written. the probability that they'll drop out falls 50% and their grade point average goes up 35%. And it is tied to precisely what you described is that people need a reason to live. And I also in this exercise, we help people break down the reasons to live. And this touches on another point that you made regarding relationships. You can't be healthy psychologically
Starting point is 01:43:27 in the absence of a network of functional relationships. You need a partner, you need a family, you need friends, you need business colleagues, you have to be nested in a functional social hierarchy. And so we walk people through this process of vision development. We ask them what they would like to have in five years, if they could have what they wanted and needed. We ask them how catastrophic their lives would
Starting point is 01:43:50 be in five years if they let their bad habits get out of control. That sort of sets the parameters, right? Don't do this and do this. And then we ask them seven questions. What do you want an intimate relationship? What do you want in your friendships? What do you want for your job and your career? How are you going to educate yourself? How are you going to take care of yourself mentally and physically? What are you going to do with your time outside of work that's productive and generous? How are you going to shoulder some civic responsibility? I think that covers the fundamental domains. Those are places that people generally find meaning in their lives. And the upshot of all this is that almost no one has an explicit
Starting point is 01:44:32 strategy for their life. And that's a catastrophe. What do they say? The people perish without a vision. This is literally the case. And this is precisely what we're talking about it. But it turns out just as in the case of exercise, you said you can get a walloping advantage from just going from zero to three hours, going from no plan at all to a hastily contrived 90-minute plan. Well, like I said, that stops half the kids from dropping out of university. And so there are, there's a large body of research showing that these sort of writing exercises to clean up your past and to structure your future
Starting point is 01:45:10 are salutary on the psychological and the physiological front. So you can imagine, there is a three prong approach to health span, right? Suficia dexercise, appropriate diet, and the development of something like a comprehensive account of and vision for your life. Well, and that would be relatively inexpensive and all things considered relatively easy to implement. So you never know, maybe we'll get smart enough to move hard in that direction as
Starting point is 01:45:40 a society over the next couple of decades. So I guess is there anything else you would like to tell people before we close? We're going to turn just so everybody's listening, knows we're going to and watching. We're going to turn to the Daily Wire Plus platform. I'm going to talk to Dr. Adi for additional half an hour about the development of his interest in these areas over his lifespan. That's usually what I do in that half an hour period. Is there anything else, Dr. Adi, that you would like to relate to the viewers and listeners before we close? No, I think those are three great principles there.
Starting point is 01:46:16 I guess the only final thing I would say, and it kind of ties a little bit into the last one, is there is an exercise I have, have my patients do called the marginal decade exercise. So you write down on a piece of paper your age, so I'm 50, and you draw a line extending across the page and you tick off at 10-year increments, so 60, 70, 80, 90. And then I do the same exercise for my kids. So I have a 15-year-old girl, nine-year-old boy, six-year-old boy, and I tick those out do the same exercise for my kids. So I have a 15 year old girl, nine year old boy, six year old boy. And I tick those out at the same 10 year increments. So the daughter of 25, 35, 45, 25,
Starting point is 01:46:53 and they're lined up, okay? And then I start to imagine when they might have kids. So this is a little bit of guessing, but I start to put, you know, grand kid one, grand kid two, grand kid three, grand kid four, okay. And then I go to what is the actual expectation of my life, which is, you know, low to mid 80s. And I ask the question, what would another decade buy me? And on one level, it doesn't look that interesting, right? It's buying me the difference between being
Starting point is 01:47:22 83 and 93. But if that 10 years is at a reasonable high level of function, and let's be clear, it's not going to look like it looks now. But I define what that function is. I still want to be able to walk up a flight of stairs. I still want to be able to carry a bag of groceries. I still want to be able to lift my suitcase up. I look down and I see what a difference it is in terms of those relationships.
Starting point is 01:47:48 It's a profound difference in the decade of that person's life and my ability to be a part of that life and for them to be a part of my life. And I say all of that because it's the why that matters a little bit here. Right, right, right, right. Well, you know, that might be part of the magic bullet in relationship to prevention, that, well, why you should eat junk food is obvious. It's immediately gratifying and delicious. So the why is a no-brainer. It's the same with abusive drugs like cocaine. We don't have to explain why people abuse cocaine.
Starting point is 01:48:25 We have to explain why all people don't abuse it 100% of the time because it immediately activates the systems that mediate positive emotion. So that's a no-brainer. If you look at the alcohol cessation literature, what you find is quite a pronounced multi-decade set of conclusions that show that if you want
Starting point is 01:48:46 to stop drinking, you need a reason. You need to find something to do that's better than drinking. And if you like alcohol, drinking is pretty good. It's a highly social activity. It's not that expensive. It's available constantly. It's an anxiolytic. It's a psychobotor stimulant. For some people. It probably increases opiate response, so it's very rewarding. Well, the problem is is that it ruins your life over a multi-decade period and blows your relationships to bits. But if you don't have a vision of yourself extending across that span of time, then why the hell should you care? And it might be the same on the exercise and nutrition fronts. Like, you're not going to take care of yourself
Starting point is 01:49:24 unless you know you have something useful to do. And I've been talking to people all over the world about taking responsibility, partly because if you take responsibility for other people, it improves your relationships. And if you have better relationships, well, you're much more resilient and you're, and you have much more of an opportunity for positive emotion. And so if you take responsibility, you have a long of an opportunity for positive emotion. And so, if you take responsibility,
Starting point is 01:49:47 you have a long-term vision of yourself as well. And so maybe the psychologists and the medical doctors can get together and figure out how to ally the work on exercise and nutritional improvement with motivation and produce prevention strategies that people will actually follow, partly because they see a reason in following them. You need a reason to make sacrifice, you know. Yeah, I think that's the key point here.
Starting point is 01:50:15 And I think that's the part, that's the point I'm trying to make with respect to emotional health, which is if you don't have this, why we're just not robots that can be programmed to do all those other things. We have to have a reason. And I think your examples are great ones. Virtually everything that is bad for your health feels much better in the moment. So to say no to that, you have to offset the hyperbolic discounting problem
Starting point is 01:50:41 of delayed gratification, you must have something that is stronger than the immediate hedonic pleasure of either not exercising, eating the wrong thing, staying up too late, pick whatever it is. Yeah, well, you know, when I want to have a banana split, which is reasonably often, I think, yeah, you know, but I'm pretty happy to have physiological constitution that's a lot more like I a lot more like it was when I was 23 than I had when I was 50. That's pretty good deal, you know,
Starting point is 01:51:17 and the value in that, I suppose that marginal decade, for example, the value in that's palpable enough so that I think, yeah, well, it is a sacrifice, but it's probably worth it. So that's the question, hey, what's it worth making a sacrifice for? And it's a question you have to answer if you're going to put your life together and put your health together.
