Muscle for Life with Mike Matthews - What 33 Studies Say About the CICO Diet for Weight Loss

Episode Date: February 10, 2020

Weight loss can seem wildly complex. Some say that carbs are the culprit when it comes to weight gain, and going low-carb is the most effective way to lose weight and keep it off for good. Others say ...that weight loss goes beyond carbs—it’s about the quality of your diet. If you avoid toxins, lectins, phytates, and other nutritional bogeymen that are menacing your metabolism, the pounds fall right off. And others say that you just need to eat clean. Eat more fresh, whole, minimally processed foods and less junk, and you’ll lose weight like clockwork. Most trends ebb and flow in cycles—liberals and conservatives in power, booms and busts in the economy, and complexity and simplicity when it comes to popular diets. It’s not surprising then, that after several decades of fake doctors, fitness gurus, and marketers shilling complex diets like The Plant Paradox diet, the ketogenic diet, the carnivore diet, the military diet, and the like, that many people are yearning for a simpler approach. It’s not surprising, then, that people are becoming tired of complicated diets, and are becoming more interested in simple ones, like the “calories in, calories out” diet, aka the CICO diet. Proponents promise that it’s the simplest, most reliable, and effective way to lose weight, and that once you try it you’ll never try another weight loss diet again. Critics say that while it can help you lose weight, it does so at the cost of your long-term health. Who’s right? The short answer is that the CICO diet isn’t really a diet at all. It simply describes the mechanism by which all diets work and have always worked—eating fewer calories than you burn. As the old saying goes, though, everything old is new again, and in this article, you’re going to learn why the CICO diet is being exhumed once more. By the end, you’ll know . . . - What the CICO diet is - Why people follow the CICO diet - What the benefits and downsides of the CICO diet are - A better way to eat than the CICO diet - And more!

Starting point is 00:00:00 If you've been in the fitness game for any amount of time now, when you hear about a new weight loss diet, especially a weight loss diet with a name like the CICO diet, you probably assume it's bullshit. And that's good. You should. You should be very skeptical of anything that you hear about nutrition, exercise, supplementation, longevity, and really anything else related to health, fitness, and wellness. There is so much bad information out there. it is staggering. And anything related to weight loss is particularly bad in this regard. There is a lot of money to be made in lying to people about how to lose weight faster, whether it is following a specific diet or exercise routine or supplementation regimen or a combination of all three or something else altogether. And so that brings us to the topic at hand, which is the CICO diet. Is it an effective weight loss diet? Does it work or is it just another fad that's going to come and go like
Starting point is 00:01:19 the many others that we've seen over the last several decades?

Hey everyone, I'm Mike Matthews, and I'm going to break down what the CICO diet is,
Starting point is 00:02:54 how it works, and how to use it effectively, which means I've already shown my hand and revealed that the CICO diet is an effective way to lose weight. It does work if you know how to work it. Why? Well, CICO stands for calories in, calories out. And so it's not really a diet in the way many people use the word or the way many people think about the word, it refers to a fundamental law of the human metabolism that dictates what happens with your body weight, that dictates weight gain, weight loss, and weight maintenance. And it's called energy balance. Now, energy balance is simply the relationship between the amount of energy that you are eating and you are burning, and it is expressed usually in calories. And when we're talking about food, a calorie is the amount of energy that's required to heat one kilogram of water one degree Celsius. And before anyone jumps in the comments trying to correct me on my
Starting point is 00:04:02 definition, use the fucking dictionary. That is the definition. Now, the reason why energy balance is so fundamental to body weight is if you are regularly consuming more energy than you're burning, more calories than you're burning, your body stores a portion of the surplus as body fat. And then on the flip side, if you are regularly burning more energy than you are flip side, if you are regularly burning more energy than you are consuming. So if you are eating fewer calories and you're burning consistently, then your body fat stores get whittled away because your body has to get that deficit somewhere. It has to get the, let's say it's 500 fewer calories than it's getting from
Starting point is 00:04:42 food every day related in relationship to how many calories it's burning. So to put real numbers to it, let's say you're burning 2,500 calories per day, but you're eating 2,000 calories per day. There's a 500 calorie deficit there to get that energy, which the body needs to get, or it would just die. Everything would just shut down. It primarily goes to body fat. So what that means is if you do that for one day, you burn 2,500 calories, you eat 2,000 calories for just one day, you've actually lost a little bit of fat. It's too little to notice, but you've lost a little bit of fat that day. You got a little bit leaner. And then of course, weight maintenance means that you more or less eat the amount of energy that you're burning every day. And it's never going to be perfect
Starting point is 00:05:29 because energy expenditure is a moving target. But really what it is, is over the course of a longer period of time, your average calorie intake more or less matches your average calorie expenditure. And you could look at that in terms of an individual day or even over the course of an entire week or even an entire month. That would get a bit odd. Practically speaking, it's most practical to look at it daily. And there are some situations where it makes sense to look at it weekly. That's more for intermediate and advanced dieters, so to speak. Okay. So that's energy balance. And what does that have to do with the CICO diet? Well, all the diet really entails is tracking your calories in and your calories out. And if you want to lose weight, making sure that you are eating fewer calories than you're
Starting point is 00:06:18 burning on a day-to-day basis, and it needs to be significantly fewer. And the reason the calorie deficit needs to be fairly large is fat is very energy dense. A pound of fat contains about 3,500 calories. And so what that means is if you want to lose one pound of fat in a week, you have to make sure that you have eaten at least 3,500 calories less than you have burned in that week. Now, the math doesn't work out perfectly. So practically speaking, you're probably going to have to eat anywhere from 4,000 to maybe 4,500 fewer calories than you burned in the week to lose a pound of fat. But you get the idea. If you are only eating 50 calories less than you're burning on a day-to-day basis, you'll lose fat, but it's
Starting point is 00:07:13 going to be very slow. Now, the big benefit of the CICO diet or this method or this approach of dieting is it is guaranteed to work for every single person, every single time, literally without exception. This is the first law of thermodynamics at work. This is a fundamental mechanism of the human metabolism that is non-negotiable, whether we're talking weight loss or weight gain. And what I mean by that is most people, even calorie skeptics would agree that you can't egregiously overeat day after day after day and not get fatter, right? Everybody knows that if you eat way too much, if you are stuffed all day because of all the food that you're eating, you're going to get fatter. Yes, that's true. And that's because of energy balance. It's because of calories in and calories out.
Starting point is 00:08:11 If you were extremely active, you could eat all that food and not gain fat. You might have to exercise or be physically active eight or 10 hours a day, but there is a point where you could eat all that food and not get fatter. Now, similarly, if you egregiously underate, if you starved yourself every day, most people would agree that, well, yeah, you do lose weight. Again, even people who are skeptical about calories in, calories out, and energy balance, they've probably tried crash dieting before. They've probably tried starvation dieting before, and they can attest to the fact that it works. It does work.
Starting point is 00:08:46 The reason it works is energy balance. Calories in, calories out. And it works quickly because there is a big imbalance between the calories in and calories out. When you crash diet, let's say you're on the HCG diet. say you're on the HCG diet. And if I remember correctly, you're supposed to eat like 500 calories per day and either inject the hormone or put it under your tongue. And what drives the weight loss there is not the hormone. Many of those products actually contained no hormones whatsoever. Welcome to the supplement industry. It was just the massive calorie deficit. So take a woman who was also exercising. Let's say she's burning 2000 calories per day, only eating 500 calories per day. That's 1500 calories that
Starting point is 00:09:34 the body has to primarily get from body fat. And so the results come quickly. Now there are a lot of bad things that happen as well. You lose muscle, you feel terrible, you can run into nutritional deficiencies or at least insufficiencies. It's not the way to go, but it does produce quick results. And so what you do is you take that approach, you make it less extreme, you make it make more sense in terms of where those calories are coming in the way of protein, carbohydrate, and fat, and make sure that you are getting enough nutrition and not overdoing it in the gym. And now all of a sudden you have a great weight loss regimen. You have something that's healthy, sustainable, and effective. And not only that, but you also
Starting point is 00:10:21 have something that's backed by over a century of research on the human metabolism. There is no scientific debate about this anymore. Scientists are not even questioning the preeminence of energy balance. They know this is how it works. And that's why countless, I'm talking about scores and scores and scores, hundreds and hundreds of controlled trials and meta-analyses and research reviews have concluded that for meaningful weight loss to occur, energy in must be less than energy out for a sustained period of time or over a sustained period of time. And this is how every weight loss diet works. Anyone who ever followed a diet that didn't explicitly revolve around calories in and
Starting point is 00:11:12 calories out, the only reason they lost weight is because one way or another, their calories in were significantly less than their calories out for long enough for meaningful weight loss to occur. less than their calories out for long enough for meaningful weight loss to occur. sports nutrition company, Legion Athletics, which produces 100% natural evidence-based health and fitness supplements, including protein powders and bars, pre-workout and post-workout supplements, fat burners, multivitamins, joint support, and more.

Now you might be wondering, well, what about certain foods? What about carbs? What about sugar? What about grains? How does that fit into the CICO diet? And how does that fit into everything I've been talking about? None of that matters. If we're just talking about
Starting point is 00:13:11 weight loss, none of that matters. You can eat as much sugar as you want. You can eat as much carbohydrate as you want. You can eat as much bread as you want. You can eat whatever you want, so long as your calories are far enough beneath your, or your calories in is far enough beneath your calories out, what you eat doesn't matter. That, however, brings me to, I wouldn't say downsides of the CICO diet, but caveats. And the caveats are, if you don't know what you're doing, if all, if I just left you with that and said, Hey, calculate, figure out, go over to legionathletics.com and search for calories burning, read the article I wrote on how many calories am I burning? Figure out approximately how many calories you're burning every day. Eat 500 fewer calories than that
Starting point is 00:13:58 every day. I don't care what you eat. Goodbye. Have fun. You will lose weight, but you are probably also going to end up losing muscle. And there's a fair chance you are going to develop maybe not nutritional deficiencies, but insufficiencies. Now, the reason for that is you might say that you want to lose weight, but really what you mean is you want to lose fat and not muscle. That's the goal, right? Even if you're not a body composition person, you're not a fitness person or a bodybuilder or whatever, you still don't want to lose muscle. You never want to lose muscle. That's never good. And one of the most important nutritional components of weight loss to ensure that you preserve muscle is eating enough protein. Protein helps preserve muscle. It's been shown in a number of studies, and this is indisputable at this point. You want to be eating enough protein. Protein helps preserve muscle. It's been shown in a number of
Starting point is 00:14:45 studies, and this is indisputable at this point. You want to be eating enough protein when you're in a calorie deficit to make sure that you hold on to the muscle that you have. And if you are new to resistance training and you get into that as well, you can even gain muscle while you're losing fat. Now, fortunately, it's pretty easy to do. If you just get about 40% of your daily calories from protein, you will do fine. That's all you got to do. For most people, that's about 0.8 to maybe one gram of protein per pound of body weight per day. Now, if you run those numbers and you're new to all of this stuff, you might be surprised at how much protein that is. Well, the thing here is if you look at that protein intake in the context of the scientific
Starting point is 00:15:30 literature, that's not a very high protein diet. That's a moderate to moderately high protein diet. You can find examples of studies where people are eating twice that amount. And in some cases may even be benefiting from it. And that's in the case of advanced weightlifters and bodybuilders, but there is a case to be made for some people in certain circumstances to eat double that amount, to eat upward of two grams of protein per pound of body weight per day. And so really this is just a matter of framing. It's a matter of perception because the average person eats so little protein, they do not eat enough. The average person does not eat enough protein just to help maintain muscle and strength as they get older. It's actually unhealthy how little protein most people eat. that kind of diet over to something like this and they start looking at what it would take to in many cases it's like double their protein intake that can feel a bit odd and even a bit
Starting point is 00:16:32 overkill it's not though again a number of studies including meta-analyses and research reviews so the the highest and best forms of evidence that we have, studies of studies where they're taking a whole bunch of trials that have been done and putting together criteria and seeing which meet those criteria and then reviewing everything together to see what the weight of the evidence is. A large body of evidence has been established that eating, again, around 40% of your daily calories or around 0.8 to 1 gram of protein per pound of body weight per day is a sweet spot for most people when they're in a calorie deficit. Okay, the second caveat for the CICO diet is if you use what you've learned here as a license to eat a bunch of junk food,
Starting point is 00:17:29 you can lose weight and you might even feel okay depending on where you're at. Because for some people, if you're overweight, losing weight is so healthy. It has such beneficial effects in the body that those can overpower any negative effects that might be occurring from eating a terrible diet. But if that goes on for too long, so if you neglect fruits and vegetables and whole grains and lean proteins and healthy fats, and you just eat a bunch of Oreos and pop tarts and pizza and hamburgers and all the other tasty things that you can try to fit into your calories, eventually you're not going to feel so good. Again, your body will start to develop nutritional deficiencies and insufficiencies, and those are going to have
Starting point is 00:18:20 ripple effects. It's going to affect your workouts if you're working out. It's going to affect your sleep. It's going to affect your energy levels. It's going to affect your focus. It will catch up with you. Simple workaround for this is just ensure that about 80% of your daily calories come from relatively unprocessed nutritious foods. And those are usually the things that you make yourself. Again, fruits, vegetables, whole grains, legumes, lean protein, healthy fats, a lot of the stuff that our moms probably told us to eat. If you get most of your calories from that stuff, you can then take, let's say 20, maybe even 30% of your calories and use them on the junk. That is a perfectly healthy and effective and enjoyable
Starting point is 00:19:09 way of going about it. And so what that means is, yes, you can have sugar every single day and lose plenty of fat and not lose muscle, maybe even gain muscle, feel good, look good. No problem. You can't eat a ton of sugar every day and do that. You might only be eating 10 to maybe 20 grams a day, but you can do that. And that means that yes, you can eat carbs. Now, if you're following my recommendations, a lot of those carbs are going to be nutritious carbs. They're not going to be highly processed sugar laden junk.. For example, you might be eating, I like oatmeal, for example. It's kind of a go-to carb for me. It's easy to make. It's tasty. I like fruit. Fruit is another go-to carb for me. I like rice. I like beans. I like whole grain bread. I like white pita bread.
Starting point is 00:20:04 I don't like whole grain or wheat pita, but if I'm eating pita, it's going to be white. And I like potatoes and the list yammers on. Anyway, you get the idea. You can eat the foods that you like, including the carbs that you like, so long as they are relatively nutritious and that you are getting, let's say three to five servings of both fruit and vegetables per day. If you have that as your base of carbohydrates, that's going to give you a lot of the nutrition you need. And then you can start adding, if you want more carbs, you can start adding on top of that. So you might want to add pasta, for example, maybe you want to have four or five ounces of
Starting point is 00:20:42 pasta with every dinner, or you want to have any of the other things that I mentioned or anything else that you might like, just start with that base of fruits and vegetables, and then start adding carbs on top of that. And make sure you eat enough protein, around 40% of your daily calories, 0.8 to one gram of protein per pound of body weight per day. And if you want mega bonus points, do a lot of heavy resistance training as well, because that really is the key to ensuring you do not lose muscle. And if you're new to it, you will gain muscle, especially if you follow a halfway decent program. Like if you follow my bigger, leaner, stronger program, which I think
Starting point is 00:21:23 is quite good. If you're a guy or if you're a gal, you'll probably want to do Thinner Leaner Stronger because it has a bit more emphasis on the lower body than the men's, which has a bit more emphasis on the upper body and a bit heavier weights on the men's program than the women's for reasons I explain in the books, Bigger Leaner Stronger and Thinner Leaner Stronger. But anyway, if you follow programs like those, and you're new to that style of training, and you follow the advice that I've shared with you here, you will gain muscle and strength at the same time. And so if you do that, let's say three to six months, what that means is by the end, you're not just going to be leaner.
Starting point is 00:21:57 You are just going to look a lot better. You are going to see muscle definition in places where you had none. Your clothes are going to fit better. You're going to notice a lot more strength. You're probably going to notice fewer aches and pains. It really is the way to go. All right. Well, that's it for today's episode. I hope you found it interesting and helpful.
