Episode Date: March 22, 2025

When you feel that urge to go to the bathroom – it just might be a good time to make an important decision. That probably sounds weird. What could the connection possibly be? Listen as I start the episode by explaining why and then it will make perfect sense. https://www.psychologicalscience.org/news/releases/full-bladder-better-decisions-controlling-your-bladder-decreases-impulsive-choices.html We live in a noisy world which is only getting noisier. Not only is there noise coming at you from the outside but also from inside your own head. All that noise can’t be good. What’s the solution? Simple silence! That’s according to Leigh Marz, a consultant and coach who is coauthor of a book called Golden: The Power of Silence in a World of Noise (https://amzn.to/3yKi203). Listen as Leigh reveals the negative effects of noise that are often hard to notice. She also has some great advice to help you turn down the volume on noise and enjoy the benefits that silence has to offer. Where do cravings come from? Why do we get them? Can you stop them? Should you ever give in to them? Here to discuss the science of cravings and how best to handle them is Amy Shah, MD. She is a board-certified medical doctor, having trained at Cornell, Columbia, and Harvard Universities. She is the author of the book I’m So Effing Hungry: Why We Crave What We Crave – and What to Do About It (https://amzn.to/3JCOHL8) It would seem sensible that your homeowner’s or renter’s insurance policy covers things related to your home. And it does. However, you might be surprised to learn what else it also covers including things that are unrelated to your home. Listen as I explain some of those likely benefits. http://consumerist.com/2012/04/12/stuck-with-a-forged-check-homeowners-insurance-to-the-rescue Learn more about your ad choices.

Today on Something You Should Know, why the next time you need to make a decision, you might want to wait until you have to go to the bathroom. Then the power of silence. It's magical because we live in a very noisy world. One way we know that is we live to emergency sirens. So in the past hundred years, those sirens have gotten six times louder in order to cut through the noise around us. The estimates that 65% of the population, about 450 million people, live with decibel

levels that are harmful to their health. Also, you might be surprised in a good way what your homeowners or renter's policy actually covers. And food cravings, why we get them and how to stop them. Getting sunlight activates a hormone called alpha MSH. That hormone makes you feel satiated. It calms the cravings and it makes you feel fuller. All this today on Something You Should Know.

Recently, I was asked to try a supplement called Mitopur and then talk about it here. And I said, well, let me check it out. So Mitopur is a precise dose of Urolithin A. That's a metabolic compound that is clinically proven to target the effects of age-related cellular decline. And it's also found in small amounts in certain fruits and nuts. Now as I've talked about many times here I work at staying fit and healthy. It's important to me and when I researched some studies online and found Urolithin A, which is what Mitopur is, is shown to deliver double-digit increases in

muscle strength and endurance and I saw that it was safe to take, I started taking it. And I've been taking it a while now, and I see a change. I have noticed improved muscle strength and endurance. Mitopure works by promoting an essential cellular cleanup process. It clears out dysfunctional mitochondria, and it's the only urolithin A supplement on the market clinically proven to target the effects of age-related cellular decline

So look I invite you to join me and awaken the strength power and resilience Already in you with the first and only supplement clinically proven to rejuvenate health at the cellular level And I'd love to hear about your results And I'd love to hear about your results. Timeline, that's the company behind Mitopure. Timeline is offering 10% off your order of Mitopure. Go to timeline.com slash something. That's T-I-M-E-L-I-N-E, timeline.com slash something. Something you should know.

Fascinating intel. The world's top experts. And practical advice you can use in your life. Today, Something you should know with Mike Carruthers. Man, this is going to sound weird to start off this episode, but if you need to make a decision, wait until you have to go to the bathroom. Research published in Science Daily says people make better decisions when they have a full bladder. That's because when the mind is struggling to restrain a bodily function, it's easier

for us to exert self-control in other areas. The authors of the study explain that when you're preoccupied with thoughts of finding the closest bathroom, your ego is in check. You're much less likely to overthink things or give in to unrelated impulses. Consequently, the decisions you make are simple and efficient and more likely to be right on the mark. And that is something you should know. You may not realize it, but we live in a very noisy world that keeps getting noisier.

And that's not an especially good thing. When was the last time you truly got to experience silence? total silence It turns out to be really good for you and all that noise Not so good for you And it's more than just that the sounds we hear have a real impact on our health and our well-being Noise can affect your mood your relationships. How well you think. It has all sorts of ramifications. And it's easy to brush it off and say,

well, it's just noise. But I invite you to take a few moments and listen to Leigh Mars. She is a consultant and coach and co-author of a book called Golden, The Power of Silence in a World of Noise. Hey, Leigh, welcome to Something You Should Know. Hey, Lee, welcome to something you should know. Hey, thanks for having me, Mike. So I think everyone has heard the phrase, silence is golden. And there was a hit record in the 60s called Silence is Golden by the Tremolos. And I think there's this general belief that silence is good, that in the right situation,

silence can be very profound and just good for you. I'm not sure how or why, but I think there's a belief in that. But why? Why is silence good? And maybe an even better first question would be, what is silence? I mean, is silence a thing, or is silence the absence of something? Oh, that's a great question. Well, on one level, it really is the absence of noise.

And we look at it coming, the noise coming to it to us through our ears and through our screens in many cases, and also the noise that's just generated by our own darn minds. But as we explore this question, the deepest silences when we asked all those interesting people, neuroscientists, politicians, artists, poets, a man incarcerated on death row, all kinds of people, we asked them that question and they pointed us towards a deep internal silence. So it's not necessarily just about what's happening outside of us, although that's also a lovely type of silence, but a silence internal that brings about a type of presence where we believe there can be

healing and enjoyment and connection and all kinds of things. And you believe that because why? Because you want to believe that or you have real evidence to believe that? Well, it's not so much that we're researchers studying that, but what we are doing in our work in the world is, for example, I work with a lot of scientists and engineers who are trying to get harmful toxic chemicals out of our products and out of our environment. And they were coming at these issues, these really complex and intractable issues, in a certain way in the four walls of their offices and under fluorescent lighting and all these things. But we took them out into the redwoods and really contemplating these issues

with big open space and open calendars and no wifi. And there really came to some novel thinking, breakthrough thinking. So really time and time and again, I am seeing the results of people tapping into silence, connecting with one another in a different way to come through that breakthrough thinking. In your definition of silence, is it all audio?

Because when you say we went out to the Redwoods, to me that's also like a visual silence. Like you're getting away from the clutter of your life and you're seeing something. It isn't nothing, but it's very peaceful. Yeah, we take the taxonomy of noise we take on in this and we could take on visual and things like that, but we kept it to auditory noise that which happens in our ears and the decibel levels, which has been exponentially on the rise in case you're wondering and the research really does bear that out. So let's talk

about that. Yeah, sure. Because that's something that, because it's so gradual, I think, that people don't realize that. But the world is getting louder, yes? And how do we know that? Yeah, it feels like it's getting louder. And it really is getting louder. So one way we know that is we look to emergency sirens as a proxy indicator for the surrounding environments.

Because of course, they need to cut through the DIN in order to get our attention. So in the past hundred years, to your point, it's been gradual, but those sirens have gotten six times louder in order to cut through the noise around us. And we do a better job measuring decibel levels in Europe overall than we do in the United States, but the estimates from the World Health Organization is that 65% of the population, about 450 million people, live with decibel levels that are harmful to their health. So on that auditory level, it is definitely getting louder. But we also thought it was important to look at information. So in 2010, the past CEO of Google,

Eric Schmidt, estimated that every two days we listen to as much information as we did from the dawn of civilization to 2003. So we are taking in the study show about five times as much information as we did just a generation ago. So there's just this overwhelming amount of information being generated and that we're trying to take in on a day-to-day level. And that we believe actually increases our internal chatter, our internal noise. So Ethan Cross, a professor at the University of Michigan, estimates that we listen to something like 320 State of the Union addresses of internal compressed speech every day. So our concern is with all this auditory, informational, and internal noise that we're really not able to tune into what is most important to us in our lives,

our relationships, our work, and our purpose for being here. So you mentioned a moment ago that all this noise, all this chatter that we have to turn the sirens up louder to get over is harmful to our health. Well, how so? Because I think people have a sense, just a sense without knowing anything, that quiet is nice and it's probably better than lots and lots of noise. But how do we know it's health related?

We know this through different studies, which look at not just the harm that comes to us in the ears. Certainly hearing loss is a serious issue that can lead to isolation and things. But it actually is also tied to cardiovascular disease, to diabetes, to loss of sleep, and all of the downstream effects of loss of sleep as well. So there's a lot of science coming out. Initially, we looked at silence as more of a control variable. So the

other side of that is the benefits of silence. So it used to be that silence was sort of where we considered a baseline to return to, but now it's actually showing in all these studies where they look at different inputs, say like pop sounds or music, classical music or silence as a control variable or so on, that silence actually leads to growth of neurons in the brain in the hippocampus in the area associated with memory. I've had the experience being in the business I'm in of being in walking into certain recording studios, radio studios, that are very well built, and that silence is different than the silence that you hear just because you turn everything off.

It is a profound silence that is deafening, almost. And it feels good. It's like, wow. It's just very relaxing. And it's an amazing experience if you've never had it. Yeah, I had that experience also walking into my brother's sound studio. And I noticed it wasn't just like what was happening in my ears, but what

it was happening in my nervous system. I just felt calmer. So it is a delicious experience to try to seek out if you can. Not all of us have a sound studio or an anechoic chamber available to us, but those who have really report to that being an extraordinary experience of sound being so different. The refracted sounds are being absorbed in those rooms. That's why it being so different. The refracted sounds are being absorbed in those rooms. That's why it's so different. Well, I do love that experience. And it's not only a lack of sound, it's a feeling.

You feel that silence. You not only hear it. Yeah, there's a great story of John Cage, the famous composer, walking into an anechoic chamber. He was very excited about silence as a musician. He certainly understood the importance of the silence between the notes that makes music what it is. So he walked into this anechoic chamber in Harvard University, and when he got in there, he heard two sounds, a high-pitched sound and a low-pitched whooshing. And so he stepped outside again after a while and asked the engineer, two sounds, a high-pitched sound and a low-pitched whooshing.

And so we stepped outside again after a while and asked the engineer, well, wait a minute, that room wasn't silent at all. I heard this high-pitched, I heard this low-pitched and the engineer said, ah, the high is your nervous system and the low is your blood in circulation. So we asked this question, is there even really a thing as silence is pure silence in a world that is vibrating and whooshing and whirling?

And the answer is probably not. But there is an experience of silence, an experience of our attention being able to put it where we want it, where we intend it. And so what about, because there's silence and there's noise, but there's also sound. And to me, I don't know how you define it, but the sound would be something that you isn't noise isn't chatter isn't objectionable. It's what you want. It's music or whatever. And even a lot of you know, people who meditate meditate to music people who study meditate or study to music and that's, well, I don't know why people do that. Why do people do that? Well, you're right in that when we're talking about noise, we're talking about unwanted distractions. So that is different from sound

or certainly music and things like that. It's also different on the informational level from data, which is neutral, you know, we like data. Or internally, it's also different on the informational level from data, which is neutral, you know, we like data. Or internally, it's also different from thought, which we also enjoy. So the distinction is that unwanted distraction. We're talking about silence and why it's so good for you. My guest is Leigh Mars.

I mean you can't sit in a room for 24 hours and have all silence. So when do you start to see the benefits

or see the bad effects of noise deteriorate with how much silence? Well, we wrote this book not for the people who can run off to retreats for six months at a time. We really wrote this book for people looking for silence in their noise-so noise soaked full lives. And we argue that you can find those micro moments and those micro moments for finding quiet can make a big difference. So that can be even when you find yourself stuck in a long line unexpectedly, or

maybe you're commuting and your radio or podcast goes out, that you could actually welcome that silence, sink into it and take advantage of that unstructured time and that open space to just not have information again coming in to you all the time, but to just appreciate the openness of that. But is there a sense of you really optimally shouldally should have, you know, so many hours of silence every day or no one's done that study? No one's really doing that study. And so we say like, do the study yourself, notice, notice what really the difference is. So the signals in the body that tell us that we are saturated by noise are different for each one of us. But I'll tell you

mine, for example, I notice a clenching in my jaw when I'm feeling saturated by noise. I'll notice an irritability with those I love most, I confess. And I'll notice that I start to kind of lose track of things. I'm repeating tasks or, you know, going back over. Things are falling through the cracks. So that's when I'm saturated with noise. Those are the signals. That's the evidence, if you will. And then when I am actually getting enough quiet, what I'll notice is that my creative thinking is much more amplified. I'm more generous with myself, with my time, with others. I do more favors for people. I just feel more abundance in life. And so for each of us, it's to look at really what are the signals that were saturated by noise and how can we take care of that, maybe turn down the dial a bit, and what are the signals that we are finding

the silence that we need and require to really be the kind of person that we want to be in this world. So I get that silence has its benefits, but it also seems sometimes that when you're sitting in silence, you can start to ruminate and think about problems and things. And that really what you want to do is distract yourself with maybe music or a podcast like this one. So you're not ruminating and thinking about your own problems,

as opposed to just sitting in total silence. What's like, I think we think of it as sort of it's the place to start because in this noise soaked environment where it is so loud and jarring and the impact of that on our health is without question, is the science we lay it out. And then the desire to get into a place of a quieter internal state, it just doesn't require absolute silence on the outside.

Although that could help, that does help some, but you mentioned for yourself it's maybe a little better to have a soundtrack or a podcast or a different place to focus. And so we're just trying to create a little bit more space for the ways that we find that internal silence that is so nourishing to us, that helps us get clear on what it is we care most about, where we put our energies and what is true in our life. And that could be in a loud environment, like I said, sort of like in my dance studio. That's, that's how it is. It's loud, but I'm quiet. When you think about it, when there's a problem, when there's conflict, the tendency is to talk more about it, to argue about it. And maybe a little silence would help rather than trying to hammer it out.

The Quakers have been doing that for hundreds of years. When there's a sense of polarity or positionality or rigidity in a meeting, the clerk will call for silence. And in that silence, an answer will come, some resolution. And so even if it means taking a break from that problem at hand, sleeping on it for a night, and coming back together, just giving a little space to it, clarity can come through that place. I wonder why people don't seek this out just on their own.

Because it does tend to feel good and relax you and make you sharper, why we don't tend to gravitate to this just because. I know, if silence is so good for us, why aren't we doing more of it? There's a few answers to that. I mean, there might be some things that we're

uncomfortable with or not wanting to face about our lives or behavior, whatever the way things are going that make it challenging. And certainly Nietzsche spoke of that hundreds of years ago, the horror of the vacuum. And my teenager will tell you, awkward silence is the worst thing under the sun to go through. So there's, I think, some nervousness and varying degrees of fear. So it's not just our personal choices that we're not, you know, choosing silence when it's so clearly good for us. It's also we have systems that are driving towards more content and data, whether it's eyeballs on a page and click through. Our pristine attention is valued at zero or time playing with children or looking at art or walking through nature. But if we're clicking through and eyeballs on a page, it's being valued by GDP. So the system is set up to make noise. So it's not just our own personal

failings here. There are things we can do to bring more silence to our lives. But there's also a system that's driving us towards making more and more noise. Yeah, well, again, there's not a lot of money in silence. Apparently not. But there is a lot of value, which takes us back to that silence that the silence is golden. So speeches silver, silence is golden is that aphorism that shows up in cultures all over the world, and the polymath Thomas Carlyle, he liked to think of that as speeches of time, silences of eternity. But what you said a moment ago that silence is scary, that rings true to me that that awkward silence that somebody's got to be talking if there's two people together because you can't have silence. That's something odd about that.

Mm hmm. Yeah, I think for many of us, it's a new it's a new terrain. And yet it's pretty old technology, if you think about it, just allowing for space for people to be together. There's certainly cultures that value that more. We look at Japanese ancient principle called ma, where the empty space is seen as pure potentiality. So the kanji character is a temple gate with slats through it, and there's golden sunlight pouring through those slats. That's the kanji character of ma. So the synonym for silence, for emptiness, but pure potentiality, which is found in the artwork of say, Ikebana flower arrangements, where the petals and the leaves of the art piece are important and featured, but so is the silence around that, the emptiness around that. Or in scroll painting, the swoosh of the brush stroke is what's at the center of the scroll, but the empty space around it is also of equal importance. And we find that in conversation,

there's more emptiness and more space to reflect. So it really trickles throughout the culture. Well, that's true, too here I mean, you know, there aren't too many people that are It's your good friends that you can sit in a room with and each read a book or do your own thing and not feel compelled to Chat, you know you there's something very comforting about that Absolutely. Yeah, one of my favorite things is to share silence because silence is magnified when it's shared. What I mean by that is that there's something inherently close to sharing silence is something that creates an intimacy in that space. And of course,

when we think about rituals and ceremonies, often those moments of shared silence or they feel pretty transformational. It's a little hard to explain this. It's a little bit in the realm of the ineffable. But what I notice in those shared moments of like a wedding or even a funeral or something when there's just some silence where the collective is holding that silence together, it's not just the poignancy of the importance of that moment, the sacredness of that moment is shared. And I feel like we come out different people with a different sense of connection.

Yeah, that's really interesting, that group silence at an important event like that. That's why people have, we're gonna have a moment of silence. And there's something very moving about that. Yeah, it's an old technology. This is not a new hack. We've been doing this for a long time and our argument is really just we need to bring a little bit more space in for more silence. We've swung a little too far in one direction. Let's

swing it back. Well, it's interesting. this is I think the first time on this podcast the topic has been not about something but about the lack of something that that silence is that lack of noise and the power that that's really in that silence. I've been talking to Lee Mars she is a consultant and coach and co-author of a book called Golden the power of silence in a world of noise and there's a link to of Silence in a World of Noise. And there's a link to that book in the show notes. Thanks, Lee. Appreciate you sharing this.

Thanks, Mike. What a pleasure. For a long time now, I've been recommending The Jordan Harbinger Show as another podcast you might want to listen to. The Jordan Harbinger Show is different than something you should know, but as you'll see, it aligns well with this audience. Meaning, if you like this podcast, you're probably going to like that one. The Jordan Harbinger Show.

Recently he had on Amanda Ripley talking about how to survive an unthinkable disaster, which strikes close to home for me having just been through the fires and mudslides in California and evacuated twice. He also spoke with Jay Dobbins, who's a former ATF agent who went undercover with the Hells Angels. Now, that's a conversation worth hearing. And listening to his conversations will make you a more critical thinker about the world around you.

Check out The Jordan Harbinger Show and there's a good chance it finds its way into your regular rotation of podcasts. The Jordan Harbinger Show on Apple Podcasts, Spotify or wherever you listen. I'm Amy Nicholson, the film critic for the LA Times. And I'm Paul Scheer, an actor, writer, and director.

Listen to unspooled wherever you get your podcasts and don't forget to hit the follow button. I'm sure you get food cravings.

I crave Thai food sometimes and chocolate, sometimes Mexican food and a few other things. Anyone who's had a craving knows a craving can be very powerful. But what is a craving? It's kind of like hunger, but it's very specific hunger. So how is it different from just being plain hungry? And perhaps more importantly, what can you do to curb those cravings and maybe even prevent them so they don't sabotage your diet? Here to discuss

all of this is Amy Shaw. Amy is a board-certified medical doctor and nutrition expert with training from Cornell, Columbia, and Harvard and she's author of a book called I'm So F-ing Hungry, Why We Crave What We Crave and What To Do About It. Hi Amy, welcome to Something You Should Know. Thank you so much for having me. My sense is that a craving, hungry is when you're hungry and you wanna eat something, and a craving is you're hungry and you wanna eat ice cream

or brownies or something very specific. Is that a fair definition? Yeah, I definitely think that that's one definition. I think even clearer to me is that it's two separate areas in the brain. In fact, working independently of each other, meaning that you could be hungry without activating the cravings area of your brain and you could be craving something without actually being hungry at all. Really? That seems weird.

It seems like every time I've ever had a craving is because I was really hungry and I wanted that particular thing. Well, I'll give you an example. Say you finished a beautiful dinner. You have eaten all the things, when the check comes and they say, oh, did you guys want any dessert?

And everyone at the table looks at each other and they're like, oh, I'm full, but kind of do want to look at the dessert menu. You know, it's like, you kind of want to see what's on there, that's cravings. That's like, you want that dopamine release in your brain that would come from chocolate or ice cream or you know some kind of dessert like item that even though you're full you're willing to order something that will give you that feeling. And so what is that? Because I've been in that

situation where I've been at a table and the waiter comes over and says, do you want to see the dessert menu? And I have no interest, but other times I think, well, that sounds pretty good. Let's take a look. So what's the difference? Our brain will want something that creates a dopamine release. And it depends on so many different things. But in general, our brain loves the feeling of a dopamine release that comes from either food or enjoyment, like, you know, going to something that you really enjoy gambling and gaming kind of fits in that category where you get a release of dopamine by doing that activity. Sometimes it's a matter of have I done it before and now my brain wants more of it. It's related to stress. It's related to what else has happened in

your day. I'll give you this example. Dopamine in our brain is created this pathway, this cravings pathway is created to keep us going back for more. So if you've had a big dessert and you had a great dopamine explosion in your brain, what your brain will do is like say, oh, I want that again. That's the dopamine pathways. It's pleasure mixed with motivation to try to get it again. And it's a pathway that probably was created, we think, to keep us motivated to find more housing, to procreate, to find more food.

So body does not want you to give up once you've found a beautiful food source. It wants you to keep coming back for more. And so dopamine, the cravings pathway is a dopamine pathway that will keep you coming back for more. And that's what gambling is. That's what gaming is. That's what desserts do for you.

That's what processed foods do. And when you don't want to give in to those cravings, you resist it. And resisting a craving can be very difficult and often ends in failure. Instead of resisting your cravings, start retraining your cravings. Start retraining yourself so that you don't have to seek out that late night dessert, the alcohol, the drugs, the gambling, all of that. So I talk about like a five step plan, but the number one thing is changing the way you eat.

So we now know that our gut bacteria is very responsible for sending signals to the brain about when we're full, when we need more, when we're craving. So getting that gut bacteria to feel full itself, to be happy is the number one goal. Eating the right foods, foods that the gut bacteria love, will help you send signals to the brain that you're full. And those foods are?

Number one is fiber. So probiotic and prebiotic fiber. Number two is polyphenols. These are the brightly colored fruits and vegetables and spices, teas and chocolate. Number three is high amino acid foods. So these are your high protein foods that really signal to the brain that you're feeling satisfied and full. Number four is dopamine producing foods. So like I mentioned, cravings pathway is due to your body wanting a dopamine release and there are foods that you can be eating to raise your base on levels

of dopamine. Number five is omega-3 fatty acid rich foods. These are things like salmon and nuts and these also trigger something called CCK, which is closest to kinene, is a satiation hormone. And number six is glucosinolates. Glucosinolates are a plant compound found in cruciferous vegetables like broccoli, cauliflower, kale, cabbage. They are full of this glucosinolate compound that feed the gut bacteria and then in turn the gut bacteria tell the body that we're full. But when people crave stuff, is it typically sweet? It can be sweet or it can be savory.

Remember, there's people who love French fries and they would have those over any kind of sweet. So salt, sugar and fat are the three things that people typically crave. And the thing is, Mike, is that food companies know this. Food companies know the science that we're talking about right now. They know how to rewire our brains

to have the most explosive dopamine release from their foods. So what they do is they figure out, okay, if we put this much salt, this much sugar, this much fat, we could actually create a food that would be so craveable that people would keep coming back for more. And that's literally the problem with the food industry today is that they're creating foods that would never have this combination in nature. They're creating foods that are so craveable that whether we're hungry or not, we're going

to go after those foods. And it's not just the food industry, the gaming industry, Instagram, gambling, porn, they all know how these pathways work. What are some examples of craveable foods? Doritos, Pepsi and Coke, McDonald's, Happy Meal. It's called Happy Meal for a reason. It's literally creating a explosion in your brain of dopamine and makes you feel happy in the moment.

But remember, dopamine is very smart. It dissipates quickly and you feel uncomfortable. You've all, right after you eat something that's got a huge dopamine release, you immediately feel a mix of pleasure and discomfort. Like, oh gosh, when am I going to get this again? You know, I got to, am I eating too much? Should I be eating this? It's like this pleasure mixed with discomfort. And our processed food industry is full of those. So McDonald's is a classic one

that everybody kind of talks about, but, and Doritos, you know, all the soda companies really work on this a lot, candies. So I've always thought, I mean, I remember hearing the advice that, you know, if you're hungry for a Snickers bar, I mean, you can fight it, or, but if you just have the Snickers bar, shouldn't that and doesn't that, have you ever studied this, where you have the Snickers bar and you go, okay that was great and life goes on? Or does it create more problems? Can't you just give into your craving and you're done? Absolutely not. It's actually the opposite. So when you understand how cravings pathways work is that the more you do it, the more you reinforce that pathway.

And so it's just like alcohol, exactly the same pathway. You have a drink, or you have a lot of drinks. And the next day you say to yourself, well, I feel like having a drink and I feel like if I just have one, it's going to be fine. I'll not have that craving anymore. And you know, we know Um, it's going to be fine. I'll not have that craving anymore. And, you know, we know now the biology behind it, you have one drink and it kind of reinforces that pathway to have want more of that, and that's exactly the same thing with processed foods. If you have that Snickers bar today, just to, just to give into your cravings.

What it does is it reinforces the pathway and it makes you want more of the Snickers. And then tomorrow you're probably going to want a Snickers and a half. And this is very true. If you ever know anyone who loves Starbucks or those Frappuccino type drinks, you know, in the beginning they taste really sweet and you can only have a little bit, but then over time you start craving it more and more. You can have a tall and then you have a grande, then you have a venti, and then before you know it, you're having a actual or jumbo size frappuccino when your craving hits. So is this primarily or exclusively a food

problem or are there other things in life that affect this? No, this is a modern life problem. Actually gambling is the best example of very very strong craveability. So what happens is when you gamble you lose, you lose, you lose, you lose, and then all of a sudden, without you anticipating it, you win. And you create this huge dopamine explosion. And it creates this pathway in your brain. Because now, once that dissipates, you're like, oh my god, I got to do that again.

Because wow, that feeling was just so delightful. So that's what the cravings pathways do. like, oh my God, I got to do that again. Because wow, that feeling was just so delightful, right? So that's what the cravings pathways does. Are there other things, things that might seem unrelated to the craving itself, that actually help to fight the craving? I guess what I mean is, so for example, if you sleep more, do you crave less?

If you're bored, do you crave more? Are there other things that can affect how much you crave something? I would love to give you an example, easy, lazy. I call it the lazy example because people love this example. Getting sunlight into your eyes activates a hormone called alpha MSH. That hormone makes you feel satiated.

And when you get adequate sunlight during the day, you increase your chances of feeling full after meals. It calms the cravings and it makes you feel fuller. And if you think about it, you know, some people will say, Oh, yeah, you know, if I go for a nice sunny walk, not only is my mood better, but I'm not craving the bad foods or bad things in my life as much. What else, what else works besides sunlight? Eating foods with protein.

So when you start to replace the right foods in back into your body, you reset your hunger hormones and your neurologic pathways and most importantly your gut bacteria. The gut bacteria will sense amino acids from proteins in your gut and it will tell your brain that hey you're getting nutrition. There is a very interesting hypothesis called the protein threshold hypothesis that says when you get enough protein in your GI tract, your brain starts to create satiation hormones,

the neuropeptide YY, the CCK, the leptin, to say to your body, all right, we got what we need. Time to stop. But if you're eating foods that are really low in protein, which is, you know, ultra processed foods, snacks, you will keep eating because your body hasn't hit that threshold yet of protein. And so this might makes it so usable to me. I said, oh, well, okay, if I want to have better control

of my cravings, I need to increase the level of protein in my meals, especially early in my meals, so that by the time I start to digest the protein, I start to get the fullness signals. And so I'm not diving into the cake or the dessert at the end of the meal. It seems that with food cravings at least, and maybe other kind of cravings,

that just letting time go by will help. That the thing that you're craving to eat, if you don't eat it, pretty soon you just don't crave it anymore. Say you ate a meal. This happens to me all the time. Say you ate a meal. This happens to me all the time. Say you ate a meal and you did order dessert, but it took forever for the waiter to put in the dessert order and for it to come back and by that time your satiation hormones have kicked in,

right? You're like, oh, I don't want it anymore. I'm done. That is a very common way to kind of get over cravings, is after a meal, just go for a walk, or maybe you do something else before you reach for that dessert. And often, your hunger hormones have kicked in, and you are fine with not having that craving at the end of the meal.

It's much harder, as you know, when your cravings are very strong. Cravings are the strongest pathways in our body. They motivate us to move, to get up out of our seat, to get in the car, to drive across town and have that thing that we're craving. So it's often not as easy as just saying, oh, well, just take a walk or, you know, distract yourself for 15 minutes. It just depends on how strong and how deeply rooted that craving might be for you.

What are some of the other hacks, tricks, first aid, whatever you want to call it, that help to work on cravings in the moment? Oh, I love the peppermint one. So peppermint oil or dark chocolate with peppermint. Peppermint works to calm the craving centers in our brain. So what they did is they actually experimented on people who sniffed peppermint every two

to three hours. And then they actually looked at their brain waves through MRI. And they found that those people who had sniffed the peppermint were much less likely to have cravings for food than the people who didn't. So that's a really easy one. And you can allude that that would be true for, even though they use peppermint oil in the study,

you can imagine that it could be like drinking a peppermint tea or having a peppermint oil in the study, you can imagine that it could be like, you know, drinking a peppermint tea or having a peppermint dark chocolate, like it could help you with those. There was another study where they use walnuts, walnuts in a smoothie. And the interesting thing like is that they gave two groups smoothies. One group had walnuts in their smoothie and the other group had something that had a texture of walnuts, but not walnuts, a placebo. And they found that over two weeks' time, the group that drank the walnut smoothie had craving centers in their brain that were calmer

and less likely to light up at the visual cues of cravings as compared to the group that just had the shake with the placebo. Are cravings predictable? Can you then say, well, given this set of circumstances, I know I'm going to end up craving something, so maybe I can stop it before it starts? Yes, absolutely. We are in control. Our brain is plastic, much more so when we're young, you know, zero to five, they're super plastic. But then even as adults, if you recognize you have a craving for something unhealthy, you can anticipate and change that. So I'll give you an example. and change that. So I'll give you an example. When I know for me, for example, that baked cookies,

like freshly baked chocolate chip cookies is something I often crave. And I know that if I keep it in the house, all I think about is when I can have that cookie, when I can have the next cookie, when I'm allowed to have that again. And I recognize that that was a craving pathway signal. And I recognized that I wanted to change that.

So what I did is instead of having chocolate chip cookies in the house, freshly baked, I had just some really high quality dark chocolate. And what I would do is when I would crave the chocolate chip cookie freshly baked, I would say to myself, well, you know what, I'm going to do a better thing. I'm going to give my body a reward, a dopamine explosion, but something that's positive, something that I could like live with and be happy with. So I gave myself the dark chocolate and I call it the intermittent reward schedule.

So what you want to do is the best way to create a pathway for a new craving is to intermittently and randomly reward yourself with a positive food or item that can reshape that pathway. And so I actually retrained my brain to crave dark chocolate. Now, for some people, that might not be good enough. They might switch it for something else. But it has to be something that creates a dopamine response

in your brain so that when you replace one for the other, you still get a good feeling. So you can't replace the baked hot chocolate chip cookie with a celery stick, because that's not going to give you the dopamine response to help you retrain your brain. Yeah, well, you got that right. I'm pretty sure that's not going to work.

I've been speaking with Amy Shaw. She's a board certified medical doctor and author of the book, I'm So F-ing Hungry, Why We Crave What We Crave and What To Do About It. And there's a link to that doctor and author of the book, I'm So F-ing Hungry, Why We Crave What We Crave and What to Do About It. And there's a link to that book in the show notes. Thanks for being here, Amy. Thank you so much.

You probably assume that your homeowner's insurance policy covers your home. And it probably does. But it may also cover a lot more things than just your home. And it probably does. But it may also cover a lot more things than just your house. There's a good chance that your homeowners policy covers you if you get stuck with counterfeit money or a forged check. It might also protect you if you get sued for libel. Fraudulent purchases and money transfers on your credit or debit card might also be covered by your homeowners policy. If something gets stolen out of your car,

your auto policy probably won't cover it, but your homeowners policy probably will. If you have renter's insurance, those things might be covered as well. It's a good idea to actually read the fine print of your policy. You might find some nice surprises. And that is something you should know. I know that leaving reviews for things can be a pain in the neck. I don't do it a lot, but I do do it for things that I do really like or experiences I really didn't like. Hopefully you have some good feelings about this podcast and you would just take a moment and leave a rating and review wherever you listen.

I'm Mike Carruthers, thanks for listening today to Something You Should Know. For a long time now, I've been recommending The Jordan Harbinger Show as another podcast you might want to listen to. The Jordan Harbinger Show is different than Something You Should Know, but as you'll see, it aligns well with this audience. Meaning, if you like this podcast, you're probably going to like that one. The Jordon Harbinger Show. Each episode is a conversation with a different, fascinating guest.

Recently he had on Amanda Ripley talking about how to survive an unthinkable disaster, which strikes close to home for me having just been through the fires and mudslides in California and evacuated twice. He also spoke with Jay Dobbins, who is a former ATF agent who went undercover with the Hells Angels. Now, that's a conversation worth hearing. And listening to his conversations will make you a more critical thinker about the world around you. Listening to his conversations will make you a more critical thinker about the world around

Or what about the Aboriginal Australian bandit who faked going into labour just to escape the police, which she did escape from them, it was a great plan.

How about the French queen who murdered her rival with poison gloves? I'm Anne Foster, host of the Feminist Women's History comedy podcast Vulgar History. Every week I share the saga of a woman from history whose story you probably didn't already know and you will never forget after you hear it. Sometimes we re-examine well-known people like Cleopatra or Pocahontas, sharing the truth behind their legends. Sometimes we look at the scandalous women you'll never find in a history textbook. Listen to Vulgar History wherever you get podcasts. And if you're curious the people I was talking about before, the Australian woman is named

Mary Anne Bug and the French actress was named Rochelle. No less name, just Rochelle. And the queen who poisoned her rival is Catherine de Medici. I have episodes about all of them.
