(crowd chatting) - All right, we're gonna get started, everybody. Thank you for coming today. It's nice to see you all here. We have the pleasure of hearing from Dr. Benjamin Bikman today. I am going to just read a little bit about him so he can be embarrassed by all of his accomplishments today. So, Dr. Bikman earned his PhD in Bioenergetics and was a post-doctoral fellow with the Duke National University of Singapore in Metabolic Disorders. Currently, his professional focus as a scientist and a professor, which he's a professor at BYU, is to better understand chronic modern day diseases with a special emphasis on the origins and consequences of obesity and diabetes. He frequently publishes his research in peer-reviewed journals and presents at international science meetings. So, we're very lucky to have him here to speak with us today. So, I'll turn the panel over to him. (audience applauding) - Yes, I'm thrilled at the invitation. One of the problems being a scientist is we paid to ask questions and to find answers to those questions, but sometimes it's not particularly gratifying when the only person who hears the answers are other scientists. So the opportunity to actually share some of these answers to these important questions with people who actually have the ability to make a difference is very gratifying. I'm thrilled at the opportunity to present some of these things that we've found and some of the questions that I've been asking over the past several years. So I hope you'll pardon the somewhat bold title here. What I hope to impress upon you is the fact that insulin resistance is not only remarkably prevalent and we'll go over the details but also particularly relevant in the context of virtually every chronic disease. I will give evidence to support some of that and would be thrilled to talk more about it at any other time you'd like. In fact, you'll have a hard time getting me to stop talking. (audience laughing) By way of an introduction, let's sort of do a history lesson. I know it's odd for a hard science professor to talk history, it's difficult, but I'll do it anyway. Something terrible happened in 1977. It was a wonderful day for Gary and Susie Bikman or a wonderful year in southern Alberta to bring another little redheaded boy onto the earth. But it was terrible for how we look at diet and disease. This is when, for the first time in the history of the planet, so far as I know, a government decided to start telling people what to eat. So this was the key aspect of what became the Food Guide Pyramid, particularly we need to eat more carbohydrates than we were, we need to eat less fat than we have been eating. That was the general change. When this happened, what most people don't know is that there was a great deal of outcry. Among the most vocal opponents of these dietary changes was the President of the National Academy of Sciences in the U.S., Dr. Philip Handler. His quote was based on the fact that there was no significant data to support these dietary recommendations. So he was calling out the government saying what right do you have to conduct an experiment with the population as the study subjects? We need to do studies before you make these recommendations. The politician up for reelection needed some sign of productivity. This was his literal exact quote. "Senators don't have the luxury "that a research scientist does "of waiting until every last shred of evidence is in." He wasn't waiting for every last shred of evidence, he wanted more evidence. But who won? Well, not the non-physician, scientist won. The politician. And this was the beginning of this significant departure from what had been very typical, normal trends in the U.S. to a significant increase in carbohydrate, a significant reduction in fat, and then no change in protein overall. This will become relevant in a little bit. So this was the whetting your appetite. I promise we'll come back to it. You might not care to. So why care about insulin resistance? Why devote my entire career to studying something that may seem as obscure as insulin resistance? The reality? It's not obscure at all. So just some general statistics. Within the U.S., 30% of the entire population is prediabetic, a.k.a. insulin resistant. Now when we look at just adults, half of all adults in the U.S. are prediabetic. Again, that's synonymous with insulin resistant. This is the single most prevalent health disorder in the country. Prediabetes, or insulin resistance. It's not strictly within our own borders or even Canada where it's not quite as high, my beloved true north. But it's close. However, when we go to other developing countries like China and India, the reason they wanted scientists like me in Singapore, where Duke Medical School has a new little branch of its medical school, to study metabolic disorders was they were mindful of the incredible increase in diabetes among two of the most predominant ethnicities in Singapore, the Chinese and the Indian ethnicities in particular. So this problem is even worse. It's more than half of the adults in China. More than half of the adults in India are prediabetic. So you can see worldwide this is a problem that is unlikely to go away soon and indeed, within all of our lifespan very likely, insulin resistance will even double. 30 years, we'll have a doubling of this. So you can see this will get far worse, likely, before it gets better. But maybe we can start making a change. So this is something that I don't wanna take too much time on, just for the sake of time, but I often will show this just to help convey the idea that this is a far more prevalent problem than you think. If you were to kind of zip through this list and you're answering some yes's and some no's, some of these you may think have nothing to do with insulin resistance. What does gout have to do with insulin resistance? Water retention? In fact, a great deal and I'd be thrilled to talk about any of these with you in more detail. The most common source of female infertility? Yes, that's fundamentally an insulin problem, increasing androgen production from the ovaries. There's a lot to talk about. But the gist of it is, if you answer yes to two or more of these questions, you're fitting within that category of very likely being prediabetic or insulin resistant. Now, remarkably, almost all of these people, there's a range, depending on the publication you look at. It's about 50 to 90% of people with insulin resistance are undiagnosed. So I'm just using the more sobering number here. But based on data, mind you, so they're undiagnosed. They don't know. They're just going through their lives. Maybe they're diagnosed with hypertension. Maybe they're diagnosed with PCOS and they have no idea that likely the fundamental feature, the fundamental source of the ideology is in fact insulin and insulin resistance. So if they're undiagnosed, how do they look? How are they acting? How is it manifesting? Well, it can manifest with any of these. Heart disease is a manifestation of insulin resistance. Even certain cancers, as we'll talk about. Things like stroke or osteoarthritis which we look at now more as a metabolic problem and less of the physical wear and tear of the joint. We're learning much, much more about it. Other things like muscle wasting. Migraines. Who'd a thunk? Are all related to insulin resistance. So in every instance here, insulin resistance is either a fundamental component or at least part of the ideology or exacerbating the course of the disease. I would readily show you evidence to support that if you'd like any time. Have me back next time. We'll go into it in more detail. So what is insulin resistance? What is this villain that I'm talking so much about and have devoted my whole career to better understanding? Insulin resistance in short can best be told by looking at the cell. So here is a cell. Every cell in the body has insulin receptors. Every single cell. I've never seen an exception but I'm always looking. So an insulin binds to its receptor. There's a series of biochemical events you've very all likely seen from biochemistry classes with any receptor. We have all these second messengers. So just to make things simple, insulin binds to its receptor and then we have an action, whatever it may be and there are hundreds or thousands of consequences of insulin binding its receptor. We typically look at only one being that it will allow glucose to come in if this were a muscle cell or a fat cell that would be true. But insulin does hundreds of other things. So insulin binds. We have an action. Over time, however, as a person becomes insulin resistant, that same stimulus is incapable of producing the same level of action as before. So the same stimulus as before is yielding a diminished reaction or action. That's insulin resistance in its sort of cleanest sense. So what can the body do to try to increase that action? What do you think? Am I allowed to make this a little interactive? If one insulin molecule, let's just say, is insufficient, what does the body do? (crowd chattering) Yeah, the body will become hyperinsulinemic in order to promote, to return what was once, to get the action back to where it once was. So there are two key features of insulin resistance. One, some cells in the body are failing to respond fully to insulin and it's not an all or nothing. You can have a cell like a liver cell and a parasite where some aspects of insulin's effects are compromised and some are happily going on their business per the norm. So one consequence, some cells aren't working well with regards to insulin. Another consequence is that the body's becoming more and more and more hyperinsulinemic so blood levels of insulin are heavy. They get higher and higher in order to overcome the cell's resistance to insulin. We'll come back to that in a moment. But just to put it in a clinical context, if we had a patient come in, I'm just arbitrarily setting that sort of so-called normal levels. They have so-called normal insulin, normal glucose, but in insulin resistance, they have to have more insulin in order to keep the same level of glucose in control. So higher insulin is allowing a normal glycemia but the insulin's working harder to keep it there. Alright, so what are the causes? This is something that we could spend a great number of hours on. That indeed was my whole post doc and even now, we study this actively. Obesity is a cause of insulin resistance. Environmental toxins, things like diesel exhaust, cigarette smoke, and many, many other things that we could, in addition in inhaling we can ingest. Like Bisphenol A, BPA, and everybody has BPA-free water bottles now, right? You know what I'm talking about? BPA has been shown to cause insulin resistance. So what these two have in common and what is on its own a separate cause is inflammation. So these are three key causes, undoubtedly important. Stress is another one, physical or emotional stress as that increases cortisol which is the key component of the stress response. Cortisol is a key insulin antagonist. So this is making us more insulin resistant. Then the elephant in the room, it doesn't seem like it would be as relevant as it is, but indeed the single most relevant variable is that insulin causes insulin resistance. Isn't that odd? If it seems odd at first it won't be in second. I submit to you that it's in fact a pretty logical series of events. It'll make sense quite readily. So increased insulin leads to insulin resistance. This is a fundamental feature, this paradox of insulin and insulin sensitivity are inversely related. So in a person who's living a lifestyle that is over time increasing their insulin chronically, insulin sensitivity over the same period of time is getting more and more diminished. So they're becoming more and more insulin resistant. This is a fundamental feature of biology and why I said that if you actually think about it, it's pretty intuitive. If you're giving, a cell is constantly exposed to a stimulus, it makes sense that we will become desensitized to that same stimulus, right? It's why we cycle antibiotics. We don't want the bacteria to become immune. So everything from bacteria to the most complex organisms, humans, if we can consider ourselves the most complex. Every organism on the planet will have a decay in its sensitivity to a chronic stimulus. The same thing's happening here. Too much insulin is causing insulin resistance. I actually took out, I had a slide here. I modified it and took it out. But if I wanted to bring you into the lab and make you insulin resistant, all we would do is give you a steady infusion, a slightly hyperinsulinemic infusion of insulin. You'd be insulin resistant within about 48 to 96 hours. We would stop the insulin infusion and your insulin sensitivity would go right back to normal. So anyone can become insulin resistant if their insulin is too high for too long. That'll become relevant when we start talking about what to do about it. So why are so many people, I said 50 to 90% of people with insulin resistance are undiagnosed. Why is it? Because we look at it wrong. If you were to have someone come in to the clinic, these are all very familiar numbers. Any clinician would look at these. You could all nod your head and you could look at these cutoffs and within some very, very close range these are gonna be the clinically acceptable cutoffs when you're looking at a patient and their risk of insulin resistance or diabetes as listed here. However, in the condition of insulin resistance a.k.a prediabetes, what's conspicuously absent? Insulin. We're not looking at insulin. So insulin has to be considered. By not looking at insulin as a diagnostic for insulin resistance, we are missing the relevant variable. We're looking at all these other things and sure they're descriptive, but they're not the single most important variable. So in this condition, to take it to an extreme, based on the widely used clinical diagnostic points with regards to diabetes and insulin resistance if you had a patient come in the average blood test, let's say here's the normal patient arbitrarily setting insulin, glucose just at normal although mind you, it's never even close to actually being even, just so that you know. I'm setting them both at normal. Someone comes into the clinic and they actually have higher than normal levels of insulin but their glucose is normal. On most blood tests in most clinics would this be clinically relevant? It wouldn't be because we wouldn't have measured the insulin. The same thing could be said if the insulin were here. The same thing could be said if the insulin were even, max, whatever that would be. Simply because most blood tests on the average, I go every year for my birthday to the BYU Health Center to get a blood test, insulin's not even, it's not even mentioned. There's no option of even getting it measured. It's only ever glucose and that's unfortunate. This scenario can happen. This is the scenario on some spectrum of insulin that typifies insulin resistance. This is frequent. Anyone with insulin resistance, this is what's happening. They have more insulin in their body and that increased insulin is enough to keep all the other things in check. Now all of a sudden, what happens when insulin is, we cannot produce enough? We are so resistant to insulin that no amount of our own insulin from our own pancreas is enough to keep glucose in check. Then glucose starts to come up. Now I have to ask would this be clinically relevant? It is because this is a diagnostic that we're very comfortable using and we have very acceptable ranges for it and it's just easy to test. Much easier than insulin which up until recently required radioactive approval. It was a very complicated asset. Glucose measurement, not complicated. So it's somewhat forgivable that we've ignored this other half of the equation, if you will. So the assumption with this diagnostic method is that glucose is the key variable but I'll show you in just a moment that it is in fact insulin. So what I would humbly add to this, again, not being the clinician, being the person whose whole job is to just sit back and ask questions. You can imagine we get paid accordingly. (audience laughing) So in this case, what I would add you try to find clinical cutoffs for insulin you'll find different numbers whereas these quantities are very widely accepted. With insulin, to the cleanest, most pure data that I can find, these are the best cutoffs I can come up with without any ulterior motives. This will seem low to some. However, what's relevant, just a couple years ago a study from the Med School at the University of Arizona found that in women, the difference between having insulin at six micro units per mil verses eight micro units per mil, both of them below a typical number of around 10. So often you'll see 10 as sort of a normal number. But just going from six to eight, the women with eight micro units a mil of fasting insulin had a doubling of their risk of type two diabetes. So this is a relevant transition. Just staying under 10, I believe is not descriptive enough. So I'm going with a little more rigorous numbers, again based purely on data. So these numbers really fit better with what we're actually seeing in primary literature. Thus, to me, when someone's asking me about their blood numbers, I'm looking at their insulin and their risk of insulin resistance or whether they are insulin resistant. Typically six and below is going to be a great number. Now just to prove that I'm not a heretic and I'm not just making these things up, this was a study, a 25 year follow up study. Down here I've highlighted the development of type two diabetes is preceded by and predicted by defects in both insulin dependent and insulin independent glucose uptakes. The defects are detectable when the patients are normal glycemic in the most cases more than a decade before the diagnosis of disease. So they're saying that 10 years before we actually detect a problem in glucose, they're manifesting problems with insulin resistance. Another study is indicating that the only marker of insulin resistance should be insulin. Not glucose. Because as I've already shown you, it's possible and indeed often the case that that hyperinsulinemia is sufficient to keep the patient in normal glycemia and thus often undetected. So measuring glucose is not enough. Insulin must be measured. Now let's get down to brass tacks. Let's talk some specifics. So here are just kind of the biggest ones that I figured were worth bringing up and among all this group what we can find in each instance is that each of them is either or both. It's a consequence of too much insulin and or a consequence of insulin not acting well. In other words, insulin resistance. So how can we lower insulin? If we had more time, I would talk about drugs and exercises. Well, we don't. So we're just gonna talk about diet 'cause this is the one that I have the most to bring although I have strong feelings about various drugs and would be thrilled to talk about that more another time. But with diet. This is where it gets a little controversial only because someone wouldn't be familiar with the incredible data supported. So there are four pillars, if you will, to cut it down to its simplest concepts. Someone who wants to mitigate their risk of insulin resistance or indeed reverse the course needs to do the following. Reducing sugar. Reducing starch. I will put this in context. That's of course a very broad class of nutrient. Increasing their dietary fat consumption and engaging in intermittent fasting. Now let's go to each of these. So firstly with sugar. This is kind of an obvious villain and it's not gonna really upset anyone that I'm implicating sugar in the context of causing insulin resistance. Sugar will increase a person's insulin almost higher than anything. So we need to have it on our radar. What's important about it is that we actually, this is obvious. We need to determine how much the patient or we, how much we'd be eating. But we also need to recognize it in all of its many, many sources because it is remarkably prevalent. Try to find a peanut butter without sugar. You can't. Try to find a ketchup. Try to find mayonnaise. Try to find salad dressing or bread. Whatever else we wanna go through. It is not easy. Sugar has pervaded our food system. You have to try and you can and I submit it's worth it to find products that don't have sugar. Who wants sugar in their ketchup anyway? I don't want it. We like the ketchup 'cause it's a little tart. We don't want it sweet. But it's everywhere. Indeed, trying to find a ketchup without sugar is profoundly difficult. But we didn't always think sugar was bad and again I can very readily defend any of these things with science if called upon. Look at this. This was in 1955. This lady standing on a scale hoping to lose weight. What? Eat candy and reduce? Reduce being the earlier term for weight loss. Yes, says the doctor. Here's why. Why is it hard to believe this doctor and his book of liquid sugar? (man mumbles) Yeah, we used to think smoking was good, too. (audience laughing) So it's not surprising that we once thought sugar was good. We're learning new things all the time and this one's a little more sobering. A wonderful decade. Good for music, bad for fashion. If sugar is so fattening, how come so many kids are thin? Boy. Imagine an advertisement like that nowadays. You couldn't do it. But it just goes to show how far we're coming in understanding where the real villains are. Now I add this. Artificial sweeteners. You want something sweet. Everybody wants something sweet from time to time and if you are beginning to appreciate how insulin-spiking sugar is, what are the alternatives? There are some alternatives and this is kind of a tricky topic in a way 'cause it's a bit muddy water. But the three sweeteners that I've found in any research that have no increase on insulin whether on their own or with a meal are these ones. Xylitol, Erythritol, Stevia because something like aspartame actually the patient alone taking aspartame, there's mixed results. It may increase insulin, it may not. But add that aspartame to a meal, in other words, that diet soda being consumed with whatever that mixed macronutrient meal is, you are increasing the insulin effect of whatever that meal had been. So again, it's muddy water. These are the three that consistently come up okay as having no insulin effect and again, I make no money by promoting that. (audience laughing) I'm not affiliated with them at all. Now what do insulin mean by less starch? I'm not making a blanket accusation against carbohydrates which is what fits in, of course, the family of starches. I'm not saying that. But I'm saying we have spent decades talking good and bad fats when in reality, we maybe should have been at least adding to the conversation, if not replacing entirely, by talking good and bad carbohydrates. This is a phenomenally broad class of nutrients and you can acknowledge that we've had our hand in it. We have been mucking around and changing things that were once very natural. For example, the wheat that we have now is indistinguishable from the wheat that prevailed 150 or 200 years ago. These are different plants and it's very well established, this isn't controversial at all. What we have now we call wheat is so different from what wheat used to be that we call that spelt or an even older one which we call einkorn. So we've mucked around when it comes to starches, just plant that seed. When people say the natural plant-based diet, well, depends on what it is. Might not be so natural. So how would I, based on data, lump some of the most prevalent carbohydrates? Sugar, of course, I'm solidly putting on the bad side based on data. Fruit juice. Where would you think that's gonna go? - [Audience] Bad side. - That's absolutely bad. This is a profoundly unnatural thing. Pure fructose without any fiber to come with it. Oh my goodness. We are doing our children and ourselves such a disservice and indeed you can have people with full blown nonalcoholic fatty liver disease and all you do is have them stop drinking soda and fruit juice and the liver clears up. There's less padded fat. Now what about a fruit smoothie? What's the difference between a fruit juice and a fruit smoothie? (audience chattering) Yeah the fruit smoothie has kept the fiber in it. But we have just brutalized that fiber. If we were eating the whole apple, for example, that's profoundly different from having sheered the fiber so sufficiently that we can now drink it without any work. We have changed the fiber. So a fruit smoothie is not as good as we like to think. So when my kids, we're gonna go out for a treat, they want Jamba Juice. I'll say alright, you can have a Jamba Juice or you can have a milkshake 'cause it's the same shite. Almost. (audience laughing) Can I not talk like that here? (audience laughing) I can talk like that at BYU. (audience laughing) Not really actually. Some of my former students in here they probably know. There's good old Bikman getting irreverent again and of course this is well-documented. (audience laughing) What about honey? Honey actually is really mixed. I'm not sure about honey yet. There's evidence to suggest it's good and bad. In fact, the most consistent evidence is to show that raw and pasteurized honey is incredibly effective as a topical ointment. Well documented. I never would have imagined this. You had people with abrasions and test subjects. People with raw honey and people not and the raw honey, it will increase the rate of healing by double, two fold. It's just remarkable. But honey, I'm not sure. I'm really not. It's nature's only source of natural sucrose in a way insofar as it's pretty evenly split with fructose and glucose. But I don't think it's an accident in nature that early man, we've mitigated this process by having our little honey farms. But once upon a time, if we wanted honey for ourselves or our families, we would have had to be prepared to undergo battle with these little (audience laughing) punks who are gonna do their best to prevent us from getting their hard-earned honey. So we would have gotten a little honey and run like the dickens and it would have been months before we tried that again. (audience laughing) So I say let's treat honey now like we used to with a great deal of respect for the little guys who made it. That's a little bit of an analogy, of course. Fruits and vegetables, eat 'em. Eat 'em. I'm not gonna get into the fine points here. For the average type two diabetic, insulin resistant individual, you can, depending on how severely diabetic they are, type two diabetic, you could, there's some more scrutiny that can go into this. In other words, the starchiest of the fruits and vegetables should in fact warrant some scrutiny. But just for the sake of time and ease we'll leave them here. In the grains, boy this just depends. It depends on what the actual grain is, how refined they are, how we're eating them. Oatmeal is a wide spectrum. Are we eating oatmeal from a little pack that's a bunch of powder? Or is it the big hardy steel cut oats that have to take 30 minutes to boil and then they're finally ready? That's the same plant but they're very different responses once we actually get it in our mouths. So this one's delicate and I appreciate especially in Utah with the predominantly LDS audience this smacks of a heretic who's challenging the world of wisdom. If you are feeling that, let's talk later and I believe there's not quite as much to reconcile as you may think. Alright, so the general conclusion with the patient hoping to mitigate their risk of prediabetes or reverse the prediabetes, just be mindful of the starchiest of the starches, these most common. Bread, pasta, white rice, potato. Now I add this. Get fermented. By that I mean I think there's something to be said for eating foods the way we used to before refrigeration practices are what they are. Once upon a time if you wanted your bread to rise you would allow the natural yeast within that bread to ferment to chew through the starches and create gas or CO2 and that would result in the rising of the bread. We bypass that with quick-acting yeast but the same thing would be said of dairy. Before refrigeration, the dairy would have fermented and it would have been kefir or sour milk. When you have let a beneficial bacteria chew through some of the natural starches you are improving the insulin sensitivity. So this is something as obvious as eating sour dough bread. Yes, calorie for calorie, sour dough bread will have less of an insulin response than normal bread. Same thing with milk verses sour milk. The same thing with adding other sources of these kind of versions of fermented foods like raw apple cider vinegar which the data support. A tablespoon in the morning with water, a tablespoon in the evening with water improves insulin sensitivity. It's such an easy thing to do. Now, increasing fat. Am I going way too fast or is this okay? - [Woman] No. - [Man] It's good. - Okay. Alright now more fat. Let me defend this. - [Man] You didn't have on your last slide. Where does chocolate go? (audience laughing) - So if it's like the, nowadays thank heavens, with all these gourmet chocolates we can really get to the good range. No question. If it's like an 80% dark chocolate and it's sweetened with something like Stevia or Erythritol, you know what? You can really enjoy that fairly frequently. You can't go banana balls with it. But it'll be on the green side. - [Man] What about nuts? - Absolutely good. No question. The fattiest of the nuts, the better. But remember peanuts aren't nuts. Where are my former dietitians? Right? Peanuts are lentils or something else. They're not nuts technically. So when we talk nuts, any study you've ever seen that talks about nuts, they're talking about the walnuts, the pistachios, almonds, whatever, cashews. - [Man] Brazil nuts. - Those are fatty. I don't know. Seeds. Yes many seeds are good too. Anyway, those would be good. They're very fatty. So that's actually in this range. So now increasing fat. Again, don't crucify me. Let me defend this before you get upset because I appreciate that this challenges the most fundamental paradigms. Even still, the American Diabetes Association of which I am a member implicates to insulin resistance. I would love to talk more about that another time. It's just a matter of how we're actually looking at the data, I believe. So more fat. Now what's the relevance of fat? What happens? Let's look at what happens when we give a human strictly individually the three macronutrients. If you give a human pure protein in case it's just one type we could have used whey here or any other pure proteins. This is the insulin response where at around 90 minutes you have what may be an increase of about three times over fasting insulin. So the change 300%. So about a three-fold increase. So proteins will increase insulin. That's not bad. That's probably a good thing insofar as the protein you've consumed increasing insulin will help with the anabolic reactions anywhere, including muscle, so it's not a bad thing. But too much protein needs to be scrutinized. There was just a study published in a very good journal just over the past few weeks looking at putting people on a high protein calorie-restricted diet and they lost weight but their insulin resistance didn't improve as much as the other people who lost a similar amount of weight. So protein is something that we can't go crazy with and indeed we should never be taking as protein powders. There is just no reason for that. If you're a body builder and you wanna get swole, you just need to eat more real food. Skip the powders. Don't drink shakes. Protein shakes. Not worth it. Alright, now what happens if you give someone a pure carbohydrate? Of course the response is much more dramatic where you can get upwards over a 10 time increase in your insulin. Now, appreciate again there's a tremendous spectrum of starches. If we were to put sugar or bread on here or potato it would be even higher. If we were to put broccoli that's gonna be much, much lower. So when it comes to carbs, not all carbs are created equal. Of course they'll be a very different insulin response. But the average carbohydrate like pure glucose we're gonna be around 10 to 15 times increase. Now what happens if you gave a person pure lard which mind you, we always look at lard as just this horrific thing. There's as much unsaturated fat in lard as there is saturated. If that pig especially has been pasture-raised and allowed to eat something other than corn and wheat which the pig wouldn't normally eat anyway, allow it to eat what it would normally eat it has much more unsaturated fats in its fat than saturated or than normal. So if you give someone pure lard, what's gonna happen to their insulin? You can't even see it barely. There's no effect whatsoever. Dietary fat has no effect on insulin. Now I appreciate how somewhat artificial that is. You could eat a pure carbohydrate in nature. You couldn't eat a pure protein in so far as I know. Erin, am I right or wrong? I think I'm right. You wouldn't eat pure fat in most cases. Typically in nature, you're gonna get fat and protein together. So I appreciate that by strictly eliminating the protein aspect, we're kind of creating something that's a little artificial but can still in our day be taken advantage of. When you're eating more pure fat, you can feed the body while keeping insulin low and that has several benefits as we'll get into. So fruit and animal fats should be primary sources of dietary fat for the patient who wants to mitigate the risk of insulin resistance or reverse the trend. What I don't have on here, vegetables oils which we can talk more about. - [Woman] What's a fruit fat? - A fruit fat. There are the three fatty fruits. (audience chatting) Avocados, olives, coconuts. Those are fruits that are meant, early man, all we would have done, we would have squished it and we would have gotten the oil out of it. But get oil from canola or soy beans? Oh, no, no. The chemical process, the pressure, the heat that you have to have to get oil from a vegetable, that's a new kid on the block and there's just not enough data out there yet for me to just blanket, throw that into the mix. We've been eating these for a millennia. Early man, we cut our teeth on these things. We can handle them. Okay, this isn't as controversial as you think. Lest some of you are still thinking of me as a heretic. I, even as a boy, remember this vividly on my grandparents' coffee table. What unfortunately has not gotten nearly as much press was this Time cover. Eat butter. Scientists label fat the enemy. Why they were wrong. This is really going mainstream. The idea that fat isn't the villain and in fact probably never has been is really becoming accepted more and more. So again, I'm not quite as crazy as it may seem. Indeed, the most recent dietary recommendations in the U.S. no longer restrict fat or cholesterol. They do place a limit on sugar. They still place a limit on saturated fat which I won't get into now but you'll notice that even though they're not saying a limit of fat like they used to, no more than 30% of calories or something, they're still kind of going along same old party lines. Eating low fat or no fat. My goal in my home is for when my kids someday leave my home and go to college, I want them to be in a place with their roommates, open up their fridge and say what is low fat yogurt? What is skim milk? No. In my home, we eat things the way God intended them to be eaten. Who am I to take fat out of milk if God put it there? (audience laughing) And so on and so forth. So we eat real food and real food has fat and that's okay. Alright so that's the end of the fat one and again, we'll defend, we'll put some of these in context when we look at some disorders if we have time. Intermittent fasting. Just for the sake of time. I emphasize the intermittent nature. This is not the same as calorie restriction. It is not the same as every meal you leave the meal hungry. I just don't think that's a sustainable idea to constantly be hungry. You are fighting fundamental urges in the body to eat and so constantly telling a patient who has insulin resistance oh you need to lose weight. How do I lose weight doctor? You need to eat less and exercise more. That doesn't work. It just doesn't work. If it worked, the problem would have ended right when it began if it were that simple. It's not sustainable. So here's just one piece of evidence looking at it made an attempt to put people at a 25% calorie restriction either as a constant part of every meal of every day for the study period, six months, or allowing them to eat liberally for five days and then restricting calories for two days to get them to the same general 25% of calorie restriction week over week for six months. Now mind you, in the end, this group actually ate more than this group. So the calories consumed in the intermittent fasting group was higher. Now let's just look at these key variables. Body weight was comparable. No statistically significant difference. So we can't say there was a difference. Body fat over the six months was not statistically different either. Now when you get to waist circumference, we're getting really close. In fact, this one is even closer. We're getting to the .05. So we're starting to see that there is a trend for statistical difference that the intermittent fasting group, the light blue, had a greater reduction in their waist circumference. Then the last thing we look at, changes in insulin sensitivity, now we have a significant departure. In fact, it's quite dramatic. Despite these error bars, it's still highly statistically significant in as little as three months and then much more noticeable at six months. So this group, by even eating more calories, by having a period of time that they were making sure their glucose came down to fasting and stayed fasting for a significant period of time, allowing insulin to come down to basal levels and stay low, that resulted in a significant improvement in their insulin sensitivity. So intermittent fasting is the context of prediabetes and insulin resistance is a relevant aspect and should at least be considered in the therapy insofar as the patient can perhaps eventually get to that point, especially as they wean themselves off of a high carbohydrate diet. - [Man] Describe intermittent fasting. We think of fasting for 24 hours. - Yeah we do. So the way I interpret this. I'll talk about that. I'll have some recommendations in just a sec. This is a study that showed that severe calorie restriction or starvation diets causes insulin resistance. So the patient who has anorexia, for example, will have profound insulin resistance. But I won't get into that. So at its simplest, I at least recommend the 12 hour fast every night. So you eat dinner at six. You don't eat anything again until six that next morning. There's some fascinating studies looking at neurological function and they do this to the patients and it's just remarkable how they improve these early stage Alzheimer patients. Then a couple times a week, skip breakfast. But again, you're eating full meals at every other meal. You're not going hog wild. You're eating until full and then you're done. Controlling the starch, avoiding the starchiest of the starches and being more liberal with fat and thus calorie number has become far less important than calorie type. Then every so often, one of two times a month, a 24 hour food and again, these are just food fasts. Food fast, food fast. Not liquid, not water. So with these four pillars I wanna just look at some data that's looking at the effects of controlling starches and being more liberal with fat. So in short, in essence, we're taking the trends that were once initiated by a government that maybe shouldn't have and we're just reversing them. We're starting to flip them on their head and we'll see what happens. So we'll look at four conditions insofar as time allows. We really don't have much. So too much body fat is a problem. Body fat is a problem of too much insulin. This isn't a new idea whatsoever. The idea that various foods, particularly these starches, increase body fat more than other foods has been very well-documented. In fact, type one diabetes is an excellent example. This is a woman. Type one diabetes. This is her thighs, her crotch, her knees are down here. What on earth is happening here? - [Man] Injection sites. - Injection sites. She's a type one diabetic. These are not tumors. She's simply not good rotating her injection sites. This is a pretty dramatic example and it's old. This one is more dramatic and not as old. This was published just last year in JAMA. This they called it in UK belly bottom syndrome. (audience laughing) He wasn't rotating his injection sites. So this is just proof of just how lipogenic insulin is. Indeed it is impossible. I know of no single circumstance in human history where a patient can gain fat or become obese without insulin driving it. It's a thyroid problem, cortisol problem, or any other steroid, nonfunctioning steroid, whether it's a brain damage problem or genetic origin, it always comes back to insulin. I actively try to find the exception. In 10 years, I've still not found one. It always comes back to insulin. Here's the first type one diabetic patient in the U.S. to get insulin. Six months later, the profound difference of course is that she, in addition to having a monthly hair do now has gained some weight. So two things happen typically when a type one diabetic begins treatment with insulin. They start eating less. They have better appetite control and they start gaining fat. This condition of a type one diabetic avoiding insulin shots to stay thin is very much a real eating disorder referred to as diabulemia. About 15% of all type one diabetics have it. What about type two diabetes? When you take a type two diabetic and in month zero, the beginning of their insulin therapy, let's look what happens. So you'll see at month zero from one to three to six, what's happening in their overall required dose of insulin to maintain normal glycemia? - [Woman] Increasing. - It's increasing. That's not surprising, right? You can appreciate now that insulin causes insulin resistance. What's happening to body weight over the same period of time? From month zero in kilograms to month six they've gained about 20 to 25 kilograms of pure fat. That's actually quite common in a type two diabetic. They start insulin therapy, they will gain a significant amount of fat in fairly little time. What's perhaps the most relevant now is what happens to how much they're eating over the same period of time. You look at their daily consumption, they're eating roughly 300 calories fewer per day at six months and yet they're 25 pounds heavier. So every day that goes by they're trying to fight this weight gain but because the more and more insulin's creating more and more insulin resistance, and the insulin is promoting the growth of the fat cell, this isn't making a difference. It's not enough. So patients with cancer, what typically happens to body weight in a cancer patient? Typically they lose weight, right? That syndrome of wasting, known as cachexia. Now this isn't the universal trend but it's common enough in insulin-secreting tumors of the pancreas, insulinomas, this study found that almost three quarters of them were gaining weight throughout the course of their cancer. Again, not a typical response when it comes to the cancer in the body. So with body fat what happens if we make these changes? Here is a study. A randomized trial, of course the goal standard. They put people on a low carb calorie-unrestricted diet. So low carb, high fat, unrestricted access to calories, verses a calorie-restricted low fat. So it's kind of the typical dogma when it comes to losing weight. The 24 weeks, which is fairly short term, there are longer studies that we could go into, we see that the fat liberals starch-controlled, not the quiet exit she hoped for, (audience laughing) (background noise drowns out speaker) So several kilograms difference in body weight even though this group is eating more calories than this group. So the calorie number was very different but of course the calorie type was too. - [Man] What qualifies as low carb? - That's a great question. There's a tremendous range. It could be simply putting it below the 50%, 60% norm which many would say, even other sort of scientists, especially in the nutrition realm, would balk that I would be even talking about lowering carbs below 50%. I am a big advocate at a minimum of going back to where we were before the food guidelines. At a minimum, which was a 40, 40, 20. That should be, in the case of insulin resistance, or someone who wants to avoid it and its consequences, a minimum macronutrient ratio. 40% fat, 40% carbs, 20% protein. But even in people who are more carb intolerant, you can really swing that ever further where it gets to a 60% fat, a 60, 20, 20 or even a little further and then you have profound benefits. More studies looking at reduction in body fat but altering. More studies looking at a low carb or a low fat diet, body mass going down more, abdominal fat going down significantly more than with carb restriction as opposed to fat restriction. Now diabetes, sorry that I'm rushing now. In fact, let's just kinda skip this one. Type two diabetes is a problem of insulin resistance. If you remove the insulin resistance there is no type two diabetes. That is a fundamental cause of the disease. So with type two diabetes, I'll just show this study. Due to the potent effect of carbohydrate restriction and decreasing blood glucose levels, we must reduce the insulin by 50% on the first day of dietary carbohydrates restriction to avoid hypoglycemia. As the weeks pass, most patients achieve normal glycemia without medication. Obese patients lose weight and patients save money because of the lack of need for medications. So this is increasingly accepted. More data dogma. The carb restriction needs to be a part of the dietary protocol for someone hoping to reduce the risk of insulin resistance or reverse it. Sulfonylureas, which are insulin-secreting drugs, they were reduced or eliminated all together. The patients who couldn't get off their insulin were able to go down to 18 units per day which is a pretty profoundly low number in an insulin-dependent diabetic. More data looking at the changes in glucose and insulin in an (mumbles). You'll see that even isocaloric diets the high fat, low carb group, look at their drop in insulin. They had a almost 50% drop in insulin as opposed to about a 15% drop in the low fat group. Heart disease. This is the one that's a little, there's a lot to it and when I appreciate that when I'm encouraging the consumption of fat, one of the most common responses is well, then they'll die of heart disease. It's just not that simple. So insulin resistance is a key component to heart disease in any of its aspects insofar as heart disease is quite an umbrella of cardiovascular disorders and as you have the patients start changing their diet, eating more fat, controlling their starches, you'll see that the triglycerides drop by roughly 50% despite eating a high fat diet compared to the low fat diet. HDL goes up by roughly 10%. Very importantly, the triglyceride HDL ratio which is the poor man's method of determining the circumference and density of LDL particles. LDL itself is not, it's a terrible predictor of heart disease. If you can look at the subclass of LDL, what the actual diameter is, is it more type B or more type A or pattern B or pattern A that becomes particularly relevant in the predictive setting. So anyway, beneficial lipid changes in every condition when you're in the context of heart disease by eating more fat. More data on that. Cancer, of all the topics, maybe this is the one, so the most common cancers are also prostate cancers and breast cancers. So the average breast tumor has six to seven times more insulin receptors on it than normal mammary tissue. Prostate cancers as well have been found to have an increased expression of insulin receptors. So they're responding, this growth signal that insulin provides. The most insulin-sensitive men have the least risk of prostate cancer. The most insulin-sensitive women have the most reduced risk of breast cancer. So insulin resistance is relevant. Part of this could be due to this thing called the Warburg Effect. Have you guys heard of this? Some of you. The Warburg Effect is the phenomenon where we see that cancer cells love glucose. They don't wanna use any other fuel to produce their ATP to fuel the growth if they don't have to. So the problem with type two diabetes is that we have this perfect storm. We have too much insulin which is an anabolic hormone telling the cancer cell to grow and we're feeding that growth by providing it with a hyperglycemic environment. That's maybe why there's such a connection between insulin resistance and diabetes and certain types of cancers. So here's some interesting studies. When you give someone an insulin-secreting drug like sulfonylureas or actual insulin therapy itself they have up to a 50% increased risk of developing cancer. Another study looking at sulfonylureas again, a drug that increases insulin secretion in the pancreas, or just insulin itself, once again you have a 30 to 90% increase in the incidence of cancer or the risk of cancer. So what happens if you do this? For the sake of time, I'll just show this one study suggesting, ketogenic is a term I haven't introduced. Just look at that as being synonymous with high fat, low carb. This is just indicating that this perhaps should be part of the therapy in addition to the well-established chemo and radiation. I am in no way suggesting this is an effective replacement. I'm not that naive. But I am informed enough to believe that there should be some role for it in clinical practice. We've got what, five minutes for questions? Not a lot, I'm sorry. I'll be thrilled to answer any questions in any time we have left. - [Woman] So you kind of put insulin as an enemy but what do you suggest for people with type one diabetes? - Yeah. - [Woman] Get well. - So a type one diabetic. The type one diabetic would want to incorporate the same dietary changes the type two diabetic would. There's something, in the end, the relevance is they just simply have to then give themselves less insulin based on what they're eating. The type one diabetic eats a doughnut, they theoretically need the same amount of insulin that my pancreas would make to handle that glucose but they're injecting it. So the relevance of this is highlighted in the fact that a type one diabetic can develop type two diabetes. Did you guys know that? It's a phenomenon referred to double diabetes. If that type one diabetic is giving themselves a lot of insulin to handle the incredible amount of starches they're eating, they will become insulin resistant and again, that's double diabetes. So they have the worst of both worlds. What else? Anything else? Yeah. - [Man] Describe the glycemic index. We see that all the time. - Yeah, the glycemic index is in fact terrible. (audience laughing) The glycemic load is very valuable. The difference between, I hope I can explain it well. The glycemic index will take the type of starch that is in that food and assume a certain amount of it. Like it will take, assume a hundred grams of starch from a watermelon and compare that to a hundred grams of starch from a piece of bread. Both of them have very high glycemic indexes. But the glycemic load actually accounts for how much starch is in that food. There's actually very little starch in that watermelon. So watermelon has a high glycemic index which gives it a sort of falsely bad reputation because the actual amount of glucose you're getting from it is profoundly low. So it has a very low glycemic load whereas bread, for example, or sugar that has a high glycemic index and glycemic load. So a low glycemic load diet, although I can appreciate the utility of glycemic index simply because it's so much better documented. We have GI numbers for almost everything. We don't quite have good glycemic load numbers for everything but insofar as a patient could and was able to let the glycemic load dictate their diet, then they'd be in great position, a great situation. But it gets a little complicated when you start mixing your nutrients together. The glycemic load of a hamburger patty is nothing but the glycemic load of the bun is tremendous. When you put the two together, it's gonna be somewhere in the middle. It just gets complicated. So just skip the bun and wrap it in lettuce. - [Man] Plus the ketchup. - Plus the ketchup. (audience laughing) And the mayo. And whatever dressing they're putting on. It's loaded with sugar. - [Man] Any effect of caffeine (mumbles) things like that? - Yeah, so caffeine has no known effect on insulin resistance that's direct. You can infuse humans and animals with caffeine. They won't become insulin resistant. I don't think it's that simple though. Caffeine increases the sensitivity to cortisol so it enhances stress response and insofar as that is an indicated, revealed phenomenon, it's hard for me not to think if cortisol's up, insulin has to work harder. We haven't seen that connection yet, though. So I appreciate the danger and the scientists making that leap. That is a leap. I'm admitting it. But caffeine is known to increase the cortisol response. The same goes for cortisol is eliciting an exaggerated response in the presence of caffeine. I am a huge opponent of caffeine personally. I don't think it should be a part of our diet, as prevalent as it is. No question, it is an addictive drug and we should treat it like that. Anything else? Did I upset anyone by encouraging the consumption of fat? I hope I didn't. I didn't mean to offend. (audience chatting) Simply inform. Okay, thank you guys, thanks. (audience applauding) Thank you.
