Introduction
YOU: On a Diet
Work Smarter, Not Harder
Most diets promise commonsense solutions to tight-pants problems: Eat less, and you’ll weigh less. Keep your mouth closed, and you’ll keep the pounds off. Sweat like a sauna-dwelling sumo wrestler, and you’ll wind up skinnier than a sheet of paper. Straightforward enough. But if it really worked that way, our bodies wouldn’t be large enough to be spotted by Google Earth. If it really worked that way, then most diets wouldn’t fail. If it really worked that way, then we all must be a bunch of rebellious hellions with mayo-covered lips and belt-busting bellies who don’t feel like following a few simple instructions.
Or it could be that most diets have it all wrong.
We believe it’s the latter.
You know why? Because most diets instruct you to take on the corn chips, meatball specials, and dessert trays with brute force. It’s you versus food in a lifetime heavyweight fight. But in that scenario, the fight is always fixed—and not in your favor. That’s because the battle against extra pounds isn’t won with force, with sweat, with trying to diet. It’s won with elegance, with smarts, and with healthy choices that become as automatic as a Simon Cowell barb.
When it comes to dieting, trying to whip fat with our weapon of willpower is the food equivalent to holding your breath under water. You can do it for a while, but no matter how psyched up you get, at some point your body—your biology—forces you to the surface gasping for air. And with most diets, your body forces you to gasp (or gulp) for food. No matter how hard you try not to eat, some hidden force deep inside is always prying your mouth back open, making it impossible for willpower to win. Instead of sparring with your waistline, it’s time you made your body an ally in the fight against fat.


Our process is to look at our overweight bodies the way scientists would: Identify the underlying biology of the problem, then find the cures. Why? Because we’re lucky enough to be in the right place at the right time—a time when the scientific world has just now started to unlock the biological mysteries that have caused us to store fat and gain weight. For the first time in our history, the scientific community is uncovering the medical evidence about food, appetite, and satiety that will allow you to tackle weight problems with the real weapon against fat: knowledge. By making this knowledge simple and accessible, we’re going to give you tools and actions to crack the code of true and lifelong waist management. In fact, our plan will help you avoid the dangerous yo-yo cycle of weight gain and weight loss. We’re going to help you reprogram your body so that you can keep off the weight you lose forever.
Through the years, many of us have been led to believe that our weight problem is about two things: calorie counting and mental toughness. While some of us may say that the weight problem is too much of the twelve-cheese lasagna, the real problem is that most of us have as much of a clue about how our bodies work as we have about how our cars do. Sure, we know the major parts and generally what they’re supposed to do. The real danger of thinking we have most of the answers is that we stop asking the questions. If we look under our hood, do we really understand the systems that make our bodies accelerate to a life of fat and the ones that slam the brake on the dangerous cookie-and-cake collisions that take place every day? Probably not, and that’s what we’re here to help you learn.
Above all, we’re going to teach you that when it comes to dieting, you need to work smart, not hard.
Following our plan, you can expect to drop up to two inches from your waist (or a dress size) within two weeks and see results steadily after that. While the end goal is what many of us look for, we believe that the path you choose to get there is what really dictates whether you make it or not. Our path looks like this:

Part 1: What a Waist! Starting here, we’ll talk about our major principles for how the body is designed to work and how our program is geared toward those functions. And we’ll also give you the biological ideals of the human body—how our bodies originally looked and functioned. We’ll also give you some self-assessment tools for figuring out your own body’s ideals. Once you know where you’re going, you’ll have a better idea of how to get there.

Part 2: The Biology of Fat. Here you’ll follow morsels of food from the pantry to the porcelain bowl and everywhere in between. We’ll start by exploring the physiology of appetite, and then we’ll dive into the science of fat—how we store it, how we burn it, how we fight it. You’ll learn what a truly amazing system your body is when you steer it in the right direction through wise nutritional and activity choices.

Part 3: The Science of the Mind. When it comes to overeating, most of us put more emphasis on what we’re noshing than on what we’re thinking. But you can’t discuss weight issues without exploring the scientific and chemical (and even spiritual) reasons why your brain hormones and your emotions drive you to the eight-enchilada special. More important, we’ll show you the strategies for making your emotions and the chemicals that drive them work for, not against, your waistline.

Part 4: The YOU Diet and Activity Plan. After you read and learn about the intricacies of your body, you’ll find the eating and activity plan that will teach your body to eat and work smart. Your body will become your gym as you gain sleek strength in your body’s foundation muscles—all without using weights. And you’ll learn to make the right decisions in the supermarket aisle and at the fast-food window. The fourteen-day plan outlines recipes, exercises, and actions you can take to live leaner and healthier.
(In our appendices, we’ll explore the medical options for dealing with weight issues—for times when you may plateau, and for those people whose weight problems have led to major medical problems.)
Now, with all the diet information that’s circulating today, sometimes it’s hard to know what’s right, and sometimes it’s hard to remember what to do even if it is. That’s why we feel that while the program is important, how you learn it—how you ingrain it as part of your lifestyle—is just as vital. As we travel through the four parts of the book, you’ll notice various ways you’ll learn about your body and how to change it. These are the five main elements we’ll use along the way:


YOU-REKA IMP

YOU-reka Moments! Like Einstein suddenly realizing that E = mc
you’ll develop deep insights that challenge your preconceptions about diets, about fat, and about your body. In the margin, you’ll see our YOU-reka imp—the signal that we’re about to come upon a moment of enlightenment by busting a myth or explaining something to you about diets that may seem 180 degrees from what you believe is true.

YOUR Body: In parts 2 and 3, as we explore the biology of your body, we’ll start each chapter by giving quick biology lessons about what really happens inside your body. We ask that you put on your metaphorical scrubs and gloves as you whiz through your arteries, travel through your intestines, and hang out in your stomach. We’ll get up close to your fat so we can see how your body handles it and how it manipulates your body. We believe that by learning about how the inside of your body works, you’ll develop the smarts you need to change how the outside looks.

YOU Tests. Through interactive quizzes and measurements, you’ll establish baselines for such vital statistics as your ideal body size and your eating personality. And you’ll also be able to test for the secret things that could be contributing to a weight problem (get a load of our tongue test on page 70). You can start in a few pages by taking the Fat Facts Test on page 17.
YOU Tips: After we explore the biology of your body to show you what bad things can happen if you make the wrong choice or have cross-wired genetics, we’ll immediately give you actions that can help turn your body around. At the end of each chapter, we’ll outline intelligent strategies—big and small—for living, eating, and moving in a more healthful way.

The YOU Diet and Activity Plan: In Part 4 (on page 191) we’ll detail the specific and simple strategies, recipes, and exercises that will lead you to the body you want—for the rest of your life. The fourteen-day YOU Diet (it’s actually so easy that we crafted a seven-day plan that you do twice) and the no-weights-required YOU Workout provide all the tools and instructions you’ll need. Best of all, they don’t take a lot of time, and they’re so easy that you can incorporate them into your life today.

So where do we start? With our first YOU-reka! moment: Your body naturally wants to take you to your optimum weight, as long as you don’t get in its way.


That’s right. For almost everyone, no matter what your genetics, the systems, organs, and processes of your body all want you to function at an ideal weight and size. With the following few principles that we’ll develop throughout the book, we’re going to teach you how you can make that happen without having to bludgeon yourself in frustration with a butter knife. These are our major principles of achieving your very best and very healthiest body.
YOU Will Choose Elegance over Force
Most dieters try to defeat their Oreo/Cheeze Doodle/custard pie infatuations with will, with deprivation, with sweat, with a “my-brain-is-stronger-than-your-crust” attitude. But trying to beat your body with mind power alone may be more painful than passing a melon-size kidney stone. Instead, you have to learn about the systems and actions that influence hunger, satiety, fat storing, and fat burning to fine-tune your corporeal vehicle so it runs on autopilot and takes you to your ultimate destination: a healthy, ideal body. (For those who want to skip ahead, you’ve probably already peeked at Part 4; however, getting to know the nuances of your body is what will help you achieve and maintain a truly healthy-size body.)
FACTOID
When you lose weight without exercise, you lose both muscle and fat, but when you gain weight without exercise, you gain only fat. It’s much easier to gain fat weight than it is to gain muscle weight which is one of the reasons why yo-yo dieting fails so miserably: When you continually gain and lose and gain and lose, you end up gaining proportionally even more fat, because of the muscle loss that takes place every time you lose.
YOU Will Learn How Your Body Thinks
True body improvement is about science. It’s about making the leap from witchcraft to hard data, from alchemy to chemistry, from speculation about what works for your body to explanations of how your body actually works. The only way you’ll understand the way calories and fat travel from that 2,000-calorie onion loaf to the back of your arm is by bringing alive the physiology of hormones, blood, organs, and muscles—by explaining the processes of digestion, starvation, fat storage, and muscle movements. When you understand the magic of physiology and the fun of biology, you’ll know what actions to take—and why you’re taking them—to reboot your body back to where it wants to be. Just as when you’re trying to help a tantruming toddler or kick-start a frozen computer, you can’t fix it unless you know what’s wrong. Know the why, and it’s much easier to handle the how—when you need to. Let’s face it, we’re not going to be sitting next to you at 10:30 p.m. when you’re pilfering a Pop-Tart. So you need to be equipped with knowledge of how your body works and reacts to that Pop-Tart so that you can defend against the little sugar-coated bugger.
YOU Will Challenge Your Beliefs about Diets
Throughout our lives, we’ve been conditioned to believe that if one thing is good for us, then more of it must be better. If you eliminate 100 calories from your daily diet, then eliminating 400 must qualify you for size 2. If you walk to lose weight, then running a marathon must nuke the fat right off your body. Well, neither idea is true. Worse, not only aren’t they true, but many of the diet myths perpetuated today actually hurt our bodies. Food deprivation, for example, drops your metabolism and makes your body want to store fat. Many of the rules, ideas, and principles you may believe about dieting—that you assume work when dieting—simply aren’t true and can very well contribute to weight issues because they keep the vicious cycle of fat loss and fat gain revolving faster than Lance Armstrong’s front wheel.
FACTOID
In men, the supplement L-carnitine-at a dose of 3 grams a day-helps muscles use carbohydrates, but it is also good for blood vessel function in both men and women.
In a way, we live on the two extremes of a pendulum. Either we swing all the way in one direction (strict, tedious dieting with a draconian low daily calorie intake), or we swing all the way in the other direction (popping cream-cheese-smothered bagels like grapes). We have to stop swinging so much and start living in the middle of that pendulum by striking a balance and avoiding the periods of extreme “ons” and “offs.”
One of the reasons why most so-called diets fail is because of a psychological and behavioral flaw that many dieters have. We desperately want to believe the simple, comforting promises that diets make—that doing A always gets us B. Because once we see that A (eating wheat germ 24–7) doesn’t always equal B (the cover of Vogue), then we get frustrated and angry, and give in to the gods of cream-filled baked goods.
Unfortunately, your body and your fat do not have a linear, two-step relationship. Instead, think of your body as an orchestra. All of its systems, organs, muscles, cells, fluids, hormones, and chemicals play different instruments, make different sounds (your intestines have dibs on first-chair tuba), and produce different results depending on how you use them. They work independently, but only when they’re played together can you appreciate the magnificent symphony of your own biology. As the conductor of your biological orchestra, you control how the instruments interact and what the final result will be.
YOU Will Make Dieting Automatic
While we want you to “not think” about eating good foods, we also know that “not thinking” may be how you got into this pants-stretching mess in the first place. When you don’t think about the consequences of ordering football-size cal-zones, you wind up with such pleasantries as high LDL (lousy type of) cholesterol, low HDL (healthy type of) cholesterol, inflammation in your arteries, and a higher risk of aging arteries that cause memory loss, heart disease, even wrinkles, as well as a steady stream of coupon offers from the large men’s department. We want your body to guide you to the right choices—without thinking about them—so that they’ll lead to the results you want. It will take some effort at the start to retrain your habits, palate, and muscles, but this program will serve as a lifelong eating, activity, and behavior plan that will become as routine as going to the bathroom before bed.
Unless you’re the rare kind of person who responds to dietary drill sergeants, you won’t find long-term solutions using traditional weight-loss methods: willpower, deprivation, fads, phases, or dead-bolting the lid of the butter pecan. Instead, using this plan, you will train yourself to never think about how much you’re eating, never think about getting on a diet or worry about coming off one, and never have to figure out formulas, zones, or, for the love of (fill in the deity of your choice), place a chicken breast on a food scale.
YOU Will Focus on Waist Management
Our society seems almost as obsessed with pounds as it is with celebrity breakups, but it’s time to shift your thinking: Studies have shown that waist circumference, not overall weight, is the most important indicator of mortality related to being overweight. Of course you’ll lose pounds on this plan, but we want you to switch your focus from a number that measures your weight to one that measures your waist. Because of its proximity to your organs, your belly fat is the most dangerous fat you can carry.


YOU Test
Take Out the Tape
Some people haven’t stepped on a scale since Laverne & Shirley played prime time. And that’s a good thing. For our purposes, you don’t need to know how much you weigh (but if you want to check your progress on this program, then go ahead and peek). All you need is a tape measure. Measure the circumference of your waist at the point of your belly button, and record the score here. (Depending on how your weight is distributed, you may need to make an adjustment to where you place the tape. If you’re obese, keep the tape measure parallel to the floor during measurement.)
YOUR SIZE:
For optimum health, the ideal waist size for women is 32½ inches; once you hit 37 inches, the dangers to your health increase. For men, the ideal is 35 inches, and the dangers to your health increase once you hit 40 inches.


While we’re going to emphasize waist over weight in this book, we also know that many of you won’t be able to resist the siren of the scale. When it comes to actual weight, you do need to stop thinking about one specific number. (“I want to get down to one hundred thirty.”) All of us have an ideal playing weight-not a weight for running marathons or making All Pro linebacker or posing for an airbrushed-anyway centerfold. This ideal playing weight is a range in which you live lean and healthy, and one in which you significantly reduce the risks of aging diseases associated with being overweight (more on all of this in Part 2).
In addition to helping you shrink your waist through diet, well also teach you the exercises that will help you achieve and maintain a healthy waist size. Now, we don’t want you to think that exercise must involve sweating like a waterfall and panting like an obscene caller, because it doesn’t. But you do need to start thinking about your body as a dartboard: it’s all about what’s in the center. You’ll be focusing on the physical activities that will help control your waist size—specifically walking and foundation-muscle training of your entire body (without growing igloo-size muscles). Well teach you simple moves that will develop all of your foundation muscles, and well teach you how to tighten your belly, improve your posture, and develop the muscles that will make you fit into your clothes better. That translates into a shapelier waist, which, studies show, makes you more attractive to others.
But let’s not overlook the management part of the waist management equation. We all know how good managers work: they plan ahead and create systems that play to people’s strengths, they set realistic goals, they measure progress, and they don’t force their employees down roads that are designed to give them a pack-your-things meeting with HR. You need to train yourself to be a good waist manager by following a plan that’s designed to help you become the CEO of your body.
You Will Focus on YOU, but Not Rely on YOU


It doesn’t matter whether you look at presidents (Lincoln or Taft), musicians (Usher or Heavy D), or tennis players (Sharapova or Serena), it’s clear that we all have different builds, just as we all have different genetics, metabolic rates, and chemical interactions. Still, there are some fundamental biological facts that are true whether you’re built like a branch or a stump. As a species, we’re programmed to gain and preserve the right amount of weight. That’s simply what our bodies are designed to do (more on that coming up). The trick is to figure out your factory settings. Then, we’ll give you the all-important lock-setting tools that will help you to reboot those factory settings so that your body maintains its ideal size and shape.
While this is a very individual challenge, it doesn’t have to be a lonely one. Life is a team game; you’ve got sports teams and surgical teams, restaurant staffs and office staffs, hip-hop clubs and calculator clubs. And of course you have the ultimate team: your family. The most successful teams all work the same way: Everybody plays a different role and contributes in his or her own way. You may have a Shaq, Kobe, or LeBron on your team, but the team can’t win the title unless everybody, not just the stars, works for the team goal.
Somehow, though, when it comes to weight control, you believe that you’re solely responsible for dropping your excess pounds and changing your habits. To make it worse, when you’re gaining weight, even the fans are chipping in on your side; the world around us wants us to gain weight in the form of big portions, drive-throughs, and family dinners that could feed a small municipality. Then when you’re trying to lose weight, it’s as if everyone’s against you; they bring junk food into the home, suggest that everyone goes out for ice cream, and feast on pork fat while you’re trying to gnaw on cauliflower.
You have to stop thinking that this game is you versus a stadium full of rib-loving opponents. Sure, you need to be the quarterback of your waist control team, but you won’t achieve success without a team that can block for you, high-five you when you’re doing well, and give you an encouraging smack on the butt when you’re not. Your starting lineup should include your doctor, maybe a nutritionist, maybe a personal trainer, and certainly scads and scads of fans like your family and friends (online or in person) who can push you, support you, and yank the bowl of candy corn away from you. But you shouldn’t be the only one relying on other people; you should use this opportunity to find a support partner who needs you as much as you need her. After all, the best kinds of satisfaction shouldn’t come from the sixth spoonful of cake batter, but from sharing knowledge and support, and helping others lose inches.


YOU Will Stop Blaming Yourself
The classic psychology of fat is this: If you’re thin, then you believe that fat people must be doing something wrong to make them fat. But if you’re fat, then you blame the environment, or your genetics, or anything else. Well, we’re going to try to eliminate that blame and use medical insights to explain the epic saga of weight-related problems. We want to move dieting past a guilt-driven and blame-ridden system, and make it a science-based system.
Of course, not everyone can look like a Cameron Diaz or a Brad Pitt. To get an idea of what your healthy weight, waist, and shape should be, you’ll need to take into account such things as bone structure, muscle mass, genetics, and risk factors associated with your weight. Here’s a fact that goes virtually unmentioned: There are clinically obese people who live with no risk of health problems, and there are CD-thin people whose risk of dying prematurely is more than a chuteless sky-diver’s. Our goal is to get you to the point where you strip away inches, you strip away the risks of being overweight, and you strip away the guilt associated with the process of always trying to do so.
YOU Will Never Be Hungry
We know exactly how you’ve felt when you’ve dieted in the past. Hungry. Famished. Three seconds away from steamrolling through a triple-dip cone with sprinkles. That recipe for dieting is one you can tear up. In fact, the only place hunger ever got you was a pair of pants that could double as curtains. To eat and work smart, your goal is never to be hungry and never to be in a state of dietary angst, where your only salvation is the 99¢ menu at the drive-through window. By keeping your hunger (and internal chemicals) in check, you’ll avoid the impetuous behaviors that send fat on an express ride to your belly.
YOU Will Make Mistakes
Look, we don’t care how motivated you are, how willing you are, how inspired you are by Eva Longoria’s body. Someday, and someday soon, a volleyball-size muffin is going to get the best of you and nudge, bribe, or cajole its way into your stomach. That’s OK. Hear that? That’s OK. You’re going to have moments when your eyes, body, and curious fingers won’t be able to turn radar lock off of the queso dip. You have to get past the concept that diets have side effects—that is, unexpected negative consequences. Instead, realize that eating plans have effects—offshoot actions, behaviors, and emotions that are simply part of everyday living. One of those effects is that you will occasionally eat things that are nutritional cigarettes; while one may not hurt you, it can get you addicted to some bad behaviors. Because of that, waist management is about developing contingency plans—plans that allow you to make mistakes and then get back on the right road. We’re going to teach you how to make a YOU-Turn when you do make mistakes with Twinkies or Tootsie Rolls or any bad-for-your-waist foods. That way, your dietary fender benders won’t turn into 100-car Autobahn pileups.


YOU Will Be Flexible—and Have Fun
Most of us want our diets to be a little like having the remote control; we want the power to make lots of choices, depending on everything from our mood to the time of day. It’s clear from research that the most successful eating plans are low-maintenance: You can follow them with your family, and you won’t feel overwhelmed by cravings. If you can do that, you’ll get results. But try to stay on a diet where you feel more isolated than a Yankees fan at Fenway Park, then chances are that the result will feel like the box-office numbers of a B-level horror flick—a miserable failure.
Eating right shouldn’t be about feeling bad. It should be about feeling strong, increasing energy, living better, feeling healthier, and having more fun than a front-row rock fan. It should be about eating without thinking and without obsessing about every forkful. Of course, we all have reasons for overeating or eating the wrong kinds of food (stress, boredom, comfort, five-cent wing specials). But our goal isn’t just for you to make by-the-book food substitutions or come to grips with your Devil Dog demons. You should be grinning—not grimacing, grunting, and growling—as the inches melt away from your waist, and laughing as your lipid profile improves. You’ll understand how, after we show you how the mind-stomach connection works by explaining how brain and belly chemicals control what the mind thinks, how the fork acts in your bodily orchestra, and how this relationship can become a cacophony in the wrong hands.
So now that we’re about to begin, you’re probably asking, What are we going to do, and how are we going to do it? Well, we’re going to give you everything you need to make a body change—through a series of elegant and effective changes based on hard science—that will stick with you for your life. Simply, this book will serve as your lifelong waist management, body-changing plan.
Best of all, when you put it all together and integrate automatic actions into your life, you’ll live by the principles you’ll need to stay fit and healthy, so that you can achieve and maintain exactly what you’re striving for:
Your ideal body.

Answers

1 a. The development of agriculture meant that we could now have foods we wanted, not needed. And that’s what provided the foundation for indulgence.
2 a. Most diets don’t reprogram you to think and eat automatically, so that eventually you’ll go off the diet just as surely as you went on it.
3 c. Eating a handful of nuts has been shown to help you stay full, while skipping meals can be detrimental because your body will go into a fat-storing, starvation mode when it doesn’t have enough calories.
4 b. Of these risks, blood pressure is the greatest indicator of health risks associated with being overweight.
5 b. Ghrelin makes you want to eat more.
6 d. Leptin keeps you full.
7 a. Cinnamon increases insulin sensitivity, which helps enhance the satiety center in your brain (and also reduces blood sugar levels as well as cholesterol levels).
8 b. Fructose, as in high-fructose corn syrup, doesn’t appear to turn off your hunger chemicals, so you do not feel full; thus you eat more.
9 a. Extreme stress (as in the case of a car accident, or even exercise) turns off your hunger. Chronic stress (like a long line of looming deadlines or family problems) can make you crave feel-good carbohydrates.
10 a. Whole-grain foods are loaded with filling fiber.
11 d. Playing video games works because it keeps your hands busy, so you can’t eat. (Training for a marathon is actually destructive to your body because of the risk to your joints, and for most people, 1,000 calories is a dangerously low daily caloric intake. Do we really need to explain colonics?)
12 c. Your liver is responsible for most metabolic functions.
13 c. PCOS is responsible for weight gain in at least 10 percent of women under age fifty. It’s now clinically called androgen excess; androgen refers to the male hormone.
14 b. Fiber fills you. A cup of oatmeal in the morning has been shown to prevent you from afternoon gorging.
15 a. Walk at least thirty minutes-at once or in intervals-every day.
16 b. Liposuction should be used to sculpt problem areas, not to remove a lot of fat.
17 d. Located next to your stomach, your omentum is fat that can cause damage to surrounding organs.
18 b. While 32½ inches or less is ideal, 37 inches is when women start seeing a greatly increased risk of weight-related disorders.
19 c. Your small intestine-with 100 million neurons-has anatomy similar to your brain.
20 d. CCK is a chemical that directly and indirectly sends a message to your brain from your guts that you’re full.
21 c. Chronic stress makes your body store more fat.
22 a. A duodenal switch is one of several surgical options for people with morbid obesity.
23 d. Bupropion, an antidepressant, has been shown to help control cravings and lead to about a 7 percent weight loss. Other antidepressants, such as tricyclic antidepressants or selective serotonin reuptake inhibitors (SSRIs), can often be associated with weight gain.
24 c. Adding a little muscle through resistance training helps your body burn more fat throughout the day.
25 c. Yo-yo dieting not only has physiological effects, because you end up gaining more weight after you’ve lost it, but it also has psychological effects.
Scoring
You get one point for each correct answer.
20 and above: Congratulations, doc. You’re an anatomical expert.

10 and below: Don’t worry, you’re about to enroll in the ultimate course in the biology, history, and anatomy of fat-which is the best way to change your body.

Chapter 1
The Ideal Body
What Your Body Is Supposed to Look Like
Diet Myths

Your body doesn’t need any fat.
Fast food is responsible for most of our fat problems.
Dieting has to be hard.

The most common question heard among overweight people isn’t “Can I have more sour cream?” It’s “Why can’t I lose weight?” While you may think you know the answer (severe pancake addiction), the real reason is biological: We’re actually hardwired to store some fat.


Our bodies have more systems that allow us to gain weight than to lose it. Historically, as we’ll see in a moment, that served us well. Today, though, we’ve poisoned the systems that help us lose weight and empowered the ones that allow us to gain it—botching up our anatomy and turning our bodies into fat-storing machines. One of your goals will be to reprogram your body so that your internal systems can work the way they did when the greatest enemy we faced was a charging wildebeest, not a cheese-drowned pork roll.
Our ancestors survived by gaining and storing weight to survive periodic famines. That has left our bodies prone to storing fat and gaining weight, tendencies that willpower alone can rarely overcome. To see how our bodies have morphed from rock-hard to sponge-soft, let’s look inside the bodies of early man and woman. They looked like stereotypical super-heroes: strong, lean, muscular, able to jump snorting mammals in a single bound.


As we evolved, we created systems and behaviors to survive when droughts and poor eyesight made picking and hunting less than successful. We learned to thrive, and we learned to eat. In early times, our diets consisted of fruits, nuts, vegetables, tubers, and wild meat—foods that were, for the most part, low in calories. That’s not to say our ancestors didn’t enjoy their foods. They consumed their sugars through fruit, and they even splurged when they came across the Paleolithic Cinnabon—a honeycomb. The difference between their splurges and ours? They came across the sweet treats only rarely; it’s not as if they popped in for a 900-calorie sugar bomb every time they went shopping for a new buffalo hide. Add that to the fact that their definition of “searching for food” included walking, stalking, and chasing, not sliding the milk carton out of the way to find the pudding pack. It was a lot of work to get food, so they naturally burned many of the calories they consumed through the physical activity of hunting and gathering.
The Heavyweight Fight: Genetics Versus Environment
It’s easy to argue that lifestyle choices and lack of willpower are responsible for weight problems (it’s the argument that lean people tend to make). But it doesn’t explain the 95 percent failure rate after two years of people who have lost fifty pounds or more; they had plenty of willpower to lose but regained the weight nonetheless. Researchers argue that obesity is more genetically linked than any other trait except height-and at least 50 percent of obesity cases clearly have genetic components. Our take: The waist control game requires two players-environment and genetics. Even if your genes have made you predestined for a life of taking up two seats, that doesn’t mean you should abdicate control over your body. When you make the right behavioral and biological changes that we outline, you’ll be able to stay healthy and avoid the bad side effects of excess weight, like diabetes, high blood pressure (hypertension), and arterial inflammation. While 10 percent of the obese population has genetic challenges that may make a supermodel contract impossible, the bigger risk with these genes is not in the weight itself but in the predispositions for risks associated with obesity. For example, one genetic problem associated with being overweight is called leptin deficiency (leptin is a hormone associated with satiety, which we’ll discuss in the next chapter). Folks who either don’t produce leptin or block its signals usually become morbidly obese, and the problem is surely genetic.
While some people have these abnormalities, they tend to be the minority of the population. If you need to worry about losing twenty-five, thirty-five, even fifty pounds, your problem is not likely to be genetic. Only when your excess weight exceeds one hundred pounds would most doctors consider testing for genetic abnormalities. Still, the example of leptin is only the tip of the scientific iceberg as far as genetics and obesity are concerned. As the fight against obesity continues, we’ll see more and more drug companies target genetic reasons for weight gain-that is, drugs that attack the genetic biochemical problems that may be contributing to your weight problem. That said, the onus of waist management still falls on you, to improve your environment and your behaviors so that your genetics can work for you, not against you.
Because salt and sugar were scarce, our ancestors mostly feasted on grains, vegetables, and meats—for good reason. The meat provided the protein, vitamins, minerals, and fatty acids that helped them grow taller and develop larger brains, while the other foods gave them nutrients such as glucose, a simple sugar found in fruit and the complex carbohydrates of plants, that they needed to grow and develop, and for energy to move. And, of course, food was always fresh, as there was no canning or refrigeration to store up food for Super Bowl parties, or to sneak in an 11 p.m. bowl of sugar-coated oats.
FACTOID
The difference between obese people and thin people isn’t the number of fat cells, it’s the size of these cells. You don’t make more fat cells the fatter you get; you have the same number of fat cells you had as an adolescent. The only difference is that the fat globules within each cell increase as you store more fat. By the way, muscles work the same way: you don’t make more muscle cells; the muscle cells get larger.
Another difference was that the meat our ancestors ate wasn’t like the meat we know today. Theirs was low in fat and high in protein; ours often comes in the form of corn-fed cows pumped up to make fattier, tastier cuts. Even today’s buffalo burger is corn-fed. Truly wild game has about 4 percent fat, while now most commercially available beef has nine times that amount. (The theory behind protein-heavy diets like Atkins is that protein reduces overall food intake and could reduce calories as well. The flaw is that eating proteins dripping in saturated fat, like bacon, isn’t exactly the same as eating the leaner, healthier forms of protein like chicken and fish.)
The result: Your tribal forefathers and foremothers could eat anytime they could harvest or catch something, and still not put on excess weight.
The lesson: Our ancestors never thought about a diet in the way we do—and their bodies had the approximate density of granite. Us? We obsess about diet more than red-carpet reporters obsess about designer dresses, and our bodies have the consistency of yogurt.
Still, we can’t blame the advent of fast food and waffle cones for all of our weight issues. The downfall started in the pre-GA. (pre-Golden Arches) era—over 10,000 years or so ago, when agriculture first appeared. Agriculture allowed us to make more advances than a seventeen-year-old boy in a movie theater, but we paid a price for them. Besides Myth Buster sparing the lives of countless mammoths, the rise of agriculture ensured that we’d always have a steady supply of food—an advantage during times of famine, a disadvantage at the $6.99 Mama’s Kitchen Eat-Everything Buffet. With a constant source of food, people became less nomadic, and communities grew closer together. While the average life span increased (thanks to the elimination of the extreme sport of tiger chasing, with, perhaps, some help from sanitation and immunization), agriculture also brought its share of downsides: more bacterial infections, shorter stature, and rotting teeth that comes from eating refined sugar and less nutritious farm-raised food (overused soil depletes food of its nutrients). Our ancestors’ diets shifted from vegetables and meat to grains from the farms, essentially hindering them from getting the diverse mix of protein and micronutrients needed for brain development.


FACTOID
During the Muslim holiday of Ramadan, people eat only after sunset so they consume all their calories at night. Should they lose weight? Anecdotal evidence, gathered by doctors watching residents working all-night shifts, indicates that people who eat all their 2,000 daily calories in one meal gain more weight than those who space those calories over three meals. Why? Because the one-timers are kicking in their starvation mode, making their bodies want to store fat rather than burn it.
The advent of agriculture essentially started the sociological shift that altered the way we lived—and the way we eat—up until this day. We could now produce food, so we could now produce what we wanted, not necessarily what we needed. Instead of making foods that could both complement our bodies and appeal to our taste buds, we started making ones that were kinder to our tongues and pocketbooks than they were to our waists.
We’re not in the business of trying to make you live like cavemen, or help you score a blue-jeans billboard, or help you become thin enough to escape between two jail bars. What we should acknowledge is that we live in a world with free will, with temptations, and with more eating options than the Mall of America. Biologically, our bodies want us to eat right. But in today’s society (cavemen didn’t have bad bosses or deadlines for annual reports), our biological drive to be the right weight and to eat right can be overcome by stress or temptation. And that has shifted many dietary decisions from biological necessities to psychological reactions. What we’re going to do is teach you how to reprogram your body to work the way it’s supposed to work—so that you eat to satisfy and to fuel rather than to console or excite. Controlling your fat isn’t about being banished with a life sentence of broccoli florets. It’s about teaching your body a little bit about the way our ancestors ate. Naturally and automatically.
YOU TIPS!
Automate Your Eating. If your waist management plan is going to work-as in, really work, for your whole life-then eating right has to become as automatic as it was for our ancestors. That’s not as insurmountable as it seems. Just look at one study from the Journal of the American Medical Association. Two groups were assigned two different diets. One went on a diet rich with good-for-you foods like whole grains, fruits, vegetables, nuts, and olive oil, foods found in the typical Mediterranean diet. The other group was not given any specific direction in terms of foods to eat but was instructed to consume specific percentages of fat, carbohydrates, and protein daily. In short, they had to think a lot about preparing foods and dividing amounts, while the first group only had general guidelines about foods to eat.


The groups weren’t given guidelines about how much to eat; they let their hunger levels dictate their hunger patterns. And when they did that, what happened? Without trying, the first group ate fewer calories, lost inches, and dropped pounds.


YOU-reka! The point: The people in the good-foods group ate the foods that naturally kept them satiated so their bodies could seek their playing weights.

The “good-for-YOU-foods group” ate significantly more fiber than the control group (32 grams versus 17 grams).
The “good-for-YOU-foods group” ate higher amounts of good-for-you omega-3 fats in the form of olives, fish, and nuts (especially walnuts). Those fats help increase the level of chemicals that make you feel satiated.
The “good-for-YOU-foods group” more than doubled their consumption of fruits and vegetables.
The “good-for-YOU-foods-group” ate the foods we recommend in the YOU Diet, didn’t obsess about calories, and enabled their bodies to do what they’re supposed to do: regulate the chemicals that are responsible for hunger and for satiety (more on this in Chapter 2).


Don’t Undereat. When our ancestors couldn’t find food and went for long periods of time without it, their bodies acted like a life preserver, storing fat in anticipation of the inevitable periods of famine. The same system works today. YOU-reka! When you try to “diet” by going for long periods of time without eating or by eating way too few calories, your brain senses the starvation and sends an SOS signal through your body to store fat because famine is on its way. That’s why people who go on extreme fasts and extremely low-calorie diets don’t lose the expected weight. They store fat as a natural protective mechanism. To lose weight you have to keep your body from switching into starvation mode. The only way to do it: Eat often, in the form of frequent healthy meals, and snacks.


Plan Your Meals. Start every day knowing when and what you’re going to eat. That way, you’ll avert the 180-degree shift between starving and gorging that occurs when you skip meals. Our fourteen-day diet (in Chapter 12) will show you how to plan your meals so that you feed your body regularly to avoid extreme periods of overeating and undereating that can lead to a gain in weight and inches.

Remember Your Ancestry


Some people say their family has big bones or big cells. Some say their family has big appetites. Some say their family just has big beer coolers. If you gained weight as an adult you can get a relatively accurate picture of what your ideal size should be by thinking about what you looked like when you were eighteen (for women) or twenty-one (for men); a time when you were at your metabolically most efficient and when you weren’t stapled to an office chair for sixty hours a week. Most people gain their weight between the ages of twenty-one and sixty, so by looking at your size at eighteen or twenty-one, you’ll have a good, though not quite scientific, idea of your factory settings. It’s not perfect, but it’s a thumbnail sketch of where you want to be. You can record your waist size (or closest guess) from when you were eighteen, but, more important, think about your shape. Ask your parents about their body sizes-or find pictures of them-when they were eighteen, to help give you a good idea of what you’re supposed to look like.
YOU Test
Stand in Front of the Mirror.
Naked. Without Sucking in Your Belly.
For some of you, this assignment may feel natural, but for most the exercise is as uncomfortable as a coach-class airline seat. We’re having you do this not to benefit the neighborhood peepers, but for two other reasons. First, we want you to realize that we’re emphasizing healthy weight. Not fashion-magazine weight, not featherweight, but healthy weight. And we think that means you have to start getting comfortable with the fact that every woman isn’t as light as a kite, and every man won’t have the body of Matthew McCanoughey. Where you want to be may not be exactly where your body wants you to be. We’re not saying you need to accept a belly that looks like four gallons of melted ice cream, but we want you to get closer to your ideal health-and that means physically and emotionally.


Second, we want you to look at your body. Now draw an outline of your body shape (both from the side and front views). Ask a partner or close friend to look at the shape you drew and tell you-honestly-if that’s approximately what your body looks like. (Your clothes can be back on at this point.) This is just a quality-control check to make sure you have an accurate self body image. (Those with eating disorders have very distorted body images, making it an obstacle for getting back to a healthy weight.) This might be the first time you’ve ever had to articulate things about what your body looks like-and that’s good.
