I want to try to combine them all, because to me, healing is really the ultimate natural wonder. Your body has a remarkable capacity to begin healing itself, and much more quickly than people had once realized, if you simply stop doing what's causing the problem. And so, really, so much of what we do in medicine and life in general is focused on mopping up the floor without also turning off the faucet. I love doing this work, because it really gives many people new hope and new choices that they didn't have before, and it allows us to talk about things that -- not just diet, but that happiness is not -- we're talking about the pursuit of happiness, but when you really look at all the spiritual traditions, what Aldous Huxley called the "perennial wisdom," when you get past the named and forms and rituals that really divide people, it's really about -- our nature is to be happy; our nature is to be peaceful, our nature is to be healthy. And so it's not something -- happiness is not something you get, health is generally not something that you get. But rather all of these different practices -- you know, the ancient swamis and rabbis and priests and monks and nuns didn't develop these techniques to just manage stress or lower your blood pressure, unclog your arteries, even though it can do all those things. They're powerful tools for transformation, for quieting down our mind and bodies to allow us to experience what it feels like to be happy, to be peaceful, to be joyful and to realize that it's not something that you pursue and get, but rather it's something that you have already until you disturb it. I studied yoga for many years with a teacher named Swami Satchidananda and people would say, "What are you, a Hindu?" He'd say, "No, I'm an undo." And it's really about identifying what's causing us to disturb our innate health and happiness, and then to allow that natural healing to occur. To me, that's the real natural wonder. So, within that larger context, we can talk about diet, stress management -- which are really these spiritual practices -- moderate exercise, smoking cessation, support groups and community -- which I'll talk more about -- and some vitamins and supplements. And it's not a diet. You know, when most people think about the diet I recommend, they think it's a really strict diet. For reversing disease, that's what it takes, but if you're just trying to be healthy, you have a spectrum of choices. And to the degree that you can move in a healthy direction, you're going to live longer, you're going to feel better, you're going to lose weight, and so on. And in our studies, what we've been able to do is to use very expensive, high-tech, state-of-the-art measures to prove how powerful these very simple and low-tech and low-cost -- and in many ways, ancient -- interventions, can be. We first began by looking at heart disease, and when I began doing this work 26 or 27 years ago, it was thought that once you have heart disease it can only get worse. And what we found was that, instead of getting worse and worse, in many cases it could get better and better, and much more quickly than people had once realized. This is a representative patient who at the time was 73 -- totally needed to have a bypass, decided to do this instead. We used quantitative arteriography, showing the narrowing. This is one of the arteries that feed the heart, one of the main arteries, and you can see the narrowing here. A year later, it's not as clogged; normally, it goes the other direction. These minor changes in blockages caused a 300 percent improvement in blood flow, and using cardiac positron emission tomography, or "PET," scans, blue and black is no blood flow, orange and white is maximal. Huge differences can occur without drugs, without surgery. Clinically, he literally couldn't walk across the street without getting severe chest pain; within a month, like most people, was pain-free, and within a year, climbing more than 100 floors a day on a Stairmaster. This is not unusual, and it's part of what enables people to maintain these kinds of changes, because it makes such a big difference in their quality of life. Overall, if you looked at all the arteries in all the patients, they got worse and worse, from one year to five years, in the comparison group. This is the natural history of heart disease, but it's really not natural because we found it could get better and better, and much more quickly than people had once thought. We also found that the more people change, the better they got. It wasn't a function of how old or how sick they were -- it was mainly how much they changed, and the oldest patients improved as much as the young ones. I got this as a Christmas card a few years ago from two of the patients in one of our programs. The younger brother is 86, the older one's 95; they wanted to show me how much more flexible they were. And the following year they sent me this one, which I thought was kind of funny. (Laughter) You just never know. And what we found was that 99 percent of the patients start to reverse the progression of their heart disease. Now I thought, you know, if we just did good science, that would change medical practice. But, that was a little naive. It's important, but not enough. Because we doctors do what we get paid to do, and we get trained to do what we get paid to do, so if we change insurance, then we change medical practice and medical education. Insurance will cover the bypass, it'll cover the angioplasty; it won't, until recently, cover diet and lifestyle. So, we began through our nonprofit institute's training hospitals around the country, and we found that most people could avoid surgery, and not only was it medically effective, it was also cost effective. And the insurance companies found that they began to save almost 30,000 dollars per patient, and Medicare is now in the middle of doing a demonstration project where they're paying for 1,800 people to go through the program on the sites that we train. The fortuneteller says, "I give smokers a discount because there's not as much to tell." (Laughter) I like this slide, because it's a chance to talk about what really motivates people to change, and what doesn't. And what doesn't work is fear of dying, and that's what's normally used. Everybody who smokes knows it's not good for you, and still 30 percent of Americans smoke -- 80 percent in some parts of the world. Why do people do it? Well, because it helps them get through the day. And I'll talk more about this, but the real epidemic isn't just heart disease or obesity or smoking -- it's loneliness and depression. As one woman said, "I've got 20 friends in this package of cigarettes, and they're always there for me and nobody else is. You're going to take away my 20 friends? What are you going to give me?" Or they eat when they get depressed, or they use alcohol to numb the pain, or they work too hard, or watch too much TV. There are lots of ways we have of avoiding and numbing and bypassing pain, but the point of all of this is to deal with the cause of the problem. And the pain is not the problem: it's the symptom. And telling people they're going to die is too scary to think about, or, they're going to get emphysema or heart attack is too scary, and so they don't want to think about it, so they don't. The most effective anti-smoking ad was this one. You'll notice the limp cigarette hanging out of his mouth, and "impotence" -- the headline is, "Impotent" -- it's not emphysema. What was the biggest selling drug of all time when it was introduced a few years ago? Viagra, right? Why? Because a lot of guys need it. It's not like you say, "Hey Joe, I'm having erectile dysfunction, how about you?" And yet, look at the number of prescriptions that are being sold. It's not so much psychological, it's vascular, and nicotine makes your arteries constrict. So does cocaine, so does a high fat diet, so does emotional stress. So the very behaviors that we think of as being so sexy in our culture are the very ones that leave so many people feeling tired, lethargic, depressed and impotent, and that's not much fun. But when you change those behaviors, your brain gets more blood, you think more clearly, you have more energy, your heart gets more blood in ways I've shown you. Your sexual function improves. And these things occur within hours. This is a study: a high fat meal, and within one or two hours blood-flow is measurably less -- and you've all experienced this at Thanksgiving. When you eat a big fatty meal, how do you feel? You feel kind of sleepy afterwards. On a low-fat meal, the blood flow doesn't go down -- it even goes up. Many of you have kids, and you know that's a big change in your lifestyle, and so people are not afraid to make big changes in lifestyle if they're worth it. And the paradox is that when you make big changes, you get big benefits, and you feel so much better so quickly. For many people, those are choices worth making -- not to live longer, but to live better. I want to talk a little bit about the obesity epidemic, because it really is a problem. Two-thirds of adults are overweight or obese, and diabetes in kids and 30-year-olds has increased 70 percent in the last 10 years. It's no joke: it's real. And just to show you this, this is from the CDC. These are not election returns; these are the percentage of people who are overweight. And if you see from '85 to '86 to '87, '88, '89, '90, '91 -- you get a new category, 15 to 20 percent; '92, '93, '94, '95, '96, '97 -- you get a new category; '98, '99, 2000, and 2001. Mississippi, more than 25 percent of people are overweight. Why is this? Well, this is one way to lose weight that works very well ... but it doesn't last, which is the problem. (Laughter) Now, there's no mystery in how you lose weight; you either burn more calories by exercise or you eat fewer calories. Now, one way to eat fewer calories is to eat less food, which is why you can lose weight on any diet if you eat less food, or if you restrict entire categories of foods. But the problem is, you get hungry, so it's hard to keep it off. The other way is to change the type of food. And fat has nine calories per gram, whereas protein and carbs only have four. So, when you eat less fat, you eat fewer calories without having to eat less food. So you can eat the same amount of food, but you'll be getting fewer calories because the food is less dense in calories. And it's the volume of food that affects satiety, rather than the type of food. You know, I don't like talking about the Atkins diet, but I get asked about it every day, and so I just thought I'd spend a few minutes on that. The myth that you hear about is, Americans have been told to eat less fat, the percent of calories from fat is down, Americans are fatter than ever, therefore fat doesn't make you fat. It's a half-truth. Actually, Americans are eating more fat than ever, and even more carbs. And so the percentage is lower, the actual amount is higher, and so the goal is to reduce both. Dr. Atkins and I debated each other many times before he died, and we agreed that Americans eat too many simple carbs, the "bad carbs," and these are things like -- (Laughter) -- sugar, white flour, white rice, alcohol. And you get a double whammy: you get all these calories that don't fill you up because you've removed the fiber, and they get absorbed quickly so your blood sugar zooms up. Your pancreas makes insulin to bring it back down, which is good. But insulin accelerates the conversion of calories into fat. So, the goal is not to go to pork rinds and bacon and sausages -- these are not health foods -- but to go from "bad carbs" to what are called "good carbs." And these are things like whole foods, or unrefined carbs: fruits, vegetables, whole wheat flour, brown rice, in their natural forms, are rich in fiber. And the fiber fills you up before you get too many calories, and it slows the absorption so you don't get that rapid rise in blood sugar. So, and you get all the disease-protective substances. It's not just what you exclude from your diet, but also what you include that's protective. Just as all carbs are not bad for you, all fats are not bad for you. There are good fats. And these are predominantly what are called the Omega-3 fatty acids. You find these, for example, in fish oil. And the bad fats are things like trans-fatty acids and processed food and saturated fats, which we find in meat. If you don't remember anything else from this talk, three grams a day of fish oil can reduce your risk of a heart attack and sudden death by 50 to 80 percent. Three grams a day. They come in one-gram capsules; more than that just gives you extra fat you don't need. It also helps reduce the risk of the most common cancers like breast, prostate and colon cancer.
