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.
YOU Test
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.

Diet Myths
Hunger is primarily dictated by what’s happening in your stomach.
The biggest battle in dieting involves willpower.
As long as a food is low-fat it’s not going to make you fat.
As much as an iPod bud in the ear, fat has become a regular part of our landscape. We see it everywhere. We see it tethered to a hunk of prime rib. We see it masquerading as a Nutter Butter. We see it crammed into evening gowns or cascading over belt buckles. We’ve seen paparazzi-haunted celebrities gain it and lose it, lose it and gain it. And, if we can bear a confidence-crushing six seconds of nudity in front of a mirror, most of us have seen our own share of flesh that droops, sags, or jiggles. So, reason would tell you that we should know as much about fat as we know about Angelina Jolie’s private life. But we don’t.
Sure, we know what it looks like, what it feels like, and that it can be as bad for our health as a steak knife lodged in our hand. But few of us really know how fat works biologically—how the Twinkie morphs from a wonderfully yellow spongy cake to the flab that conjoins our inner thighs, or how our skinny-as-a-straw friend can wolf down a meat-lover’s supreme while we feel bloated if we as much as sniff four carrots.
Starting in this chapter and continuing throughout the rest of part 2, we’ll show you the way that food travels—from the time your body wants you to eat it, to the time it exercises squatter’s rights on your hips, to the time you fry it into oblivion. The best place to start? With your appetite. Appetite really comes in two forms: physiological signals that make you hungry and emotional coaxes that lure you to food.
In this chapter, we’ll explore those physiological signals, because understanding and controlling your hunger and satiety signals will help you adopt a healthy eating plan. (We’ll explore the psychological and emotional
