Our bodies have more systems that allow us to gain weight than to lose it. 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 cheesedrowned 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.
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. 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? 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.
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. 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.
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.
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.
The only difference is that the fat globules within each cell increase as you store more fat. 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.
Truly wild game has about 4 percent fat, while now most commercially available beef has nine times that amount. The theory behind protein- 32 heavy diets like Atkins is that protein reduces overall food intake and could reduce calories as well. 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. We obsess about diet more than red-carpet reporters obsess about designer dresses, and our bodies have the consistency of yogurt. The downfall started in the pre-G. Agriculture allowed us to make more advances than a seventeen-year-old boy in a movie theater, but we paid a price for them.
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.
Should they lose weight? Anecdotal evidence, gathered by doctors watching residents working all-night shifts, indicates that people who eat all their 2, daily calories in one meal gain more weight than those who space those calories over three meals. 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. 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. And that has shifted many dietary decisions from biological necessities 33 to psychological reactions. Naturally and automatically. 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. 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. And when they did that, what happened? Without trying, the first group ate fewer calories, lost inches, and dropped pounds. 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.
Those fats help increase the level of chemicals that make you feel satiated. The same system works today. 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. 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.
Some say their family has big appetites. Some say their family just has big beer coolers. You can record your waist size or closest guess from when you were eighteen, but, more important, think about your shape. 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.
Not fashion-magazine weight, not featherweight, but healthy weight. Where you want to be may not be exactly where your body wants you to be. Second, we want you to look at your body. Now draw an outline of your body shape both from the side and front views. 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.
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. 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. 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.
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. Once you know that those mechanisms have much more powerful control over how you eat than do your taste buds, then you can make the behavioral, attitudinal, and biological adjustments you need to live at your healthy weight.
But despite potentially serious consequences, fat, by nature, is good. Besides helping Santa hopefuls land December jobs, it also helps your cells function and provides insulation. Most of your fat is stored in a reservoir throughout your body.
You have drums and drums of it, sitting passively, just waiting to be burned. But you have another kind of fat, too. This increases in outdoor workers during cold spells to protect them from the weather; it insulates our vital organs.
What makes brown fat different? Brown fat is alive. It has nerve fibers, like any organ, and it also has leptin receptors. When the level of this hormone goes up, it turns on energy consumption in the brown fat and burns it. This is important 39 because it shows that the right leptin levels can signal you to immediately get rid of this fat.
That sign? Instead, it will be the chemicals in your brain and body. But to understand appetite, you have to navigate farther north—to the place that may hold the least fat. Among the biological functions it controls are your temperature, your metabolism, and your sex drive. Located in the center of your brain, the hypothalamus see Figure 2. At least one person we know helped curb an eating problem by having regular, monogamous, healthy sex.
When the appetite function for sex was satisfied, the appetite function for food was diverted. FACTOID As you get older, you have fewer leptin receptors in your hypothalamus—meaning that you have fewer satiety signals, which makes you more prone to gaining weight.
Hidden in your hypothalamus, you have a satiety center that regulates your appetite. It is controlled by two counterbalancing chemicals that are located side by side see Figure 2. CART stimulates the surrounding hypothalamus to increase metabolism, reduce appetite, and increase insulin to deliver energy to muscle cells rather than be stored as fat.
NPY has the opposite effect on the hypothalamus; it decreases metabolism and increases appetite. Think of these two command chemicals as any game or sport that involves offense and defense, like soccer, checkers, or even dating.
The offense is always trying to make advances, trying to score points, and trying to attack, while the defense protects its territory. They want as many points as possible, so they fire off those signals for your body to score: eat, eat, eat, calories, calories, calories, chimichanga, chimichanga, chimichanga. The biological message: Prevent starvation by eating. Meanwhile, your satiety chemicals play defense, like a goalkeeper, the back row of checkers, or a protective parent.
How do we know these centers work this way? For one, by looking at extremes and seeing what happens when the feeding system is turned completely on or off. The resulting severe anorexia starves the body of all energy and nutrients so that it withers away to the approximate width of an envelope.
In rats whose eating center is overstimulated, though, food is always on the radar screen. And those rats eat themselves to death—literally—by increasing their fat-induced diseases like diabetes, hypertension, and arthritis. Figure 2. The hormone leptin goes to the satiety center to make you feel full and satisfied, while the signal from the hormone ghrelin makes you want to eat, gorge, and slobber over your every feast.
Each chemical readily travels to other nuclei in the hypothalamus. NPY causes our temperature to drop and our metabolism to decrease as we feel hungry. CART stimulates the opposite influence. The nearby mammillary body literally shaped like a nipple is part of our limbic system, where we store memories and emotions—just the right combination to create a craving for a favorite food. Cocaine and amphetamine stimulate this chemical, giving you a double brain bat to help you control appetite and increase metabolism.
Marijuana, by the way, has its own receptors that overwhelm leptin, which is one big reason why pot smokers get the munchies. The prototype drug has done great in trials and symbolizes a new generation of smart weight-loss medications that work hormonally.
You can take comfort and find motivation in the fact that your body wants you to reach your goals. Take the case of rats made obese by force-feeding. They eat what they should eat, without thinking. Same goes for starving rats. They naturally go back to their control weight.
And we know from years and years of research that what rats do is a pretty fair indication of what humans will do under the same circumstances. You do it by developing a welltrained defense that naturally balances the offense. Though it may not always be the case in football or Scrabble, when you pit offense against defense in your body, the offense in your body typically attacks more aggressively. Your body does it naturally through the communication of substances controlled by your brain.
But we also think that fat has an unfair knock against it. Fat is treated a little like an accused suspect; it sometimes gets a bum rap. Fat produces a chemical signal in your blood that tells you to stop eating. How does fat curb appetite? Through one of the most important chemicals in the weight-reduction process: leptin, a protein secreted by stored fat. In fact, if leptin is working the way it should, it gives you a double whammy in the fight against fat.
This may be why some people in chronically stressful situations tend to gain weight. In some research, when leptin was given to mice, their appetites decreased, as expected.
When it was given to people, they initially got thin, but then something strange happened: They overcame the surge of leptin and stopped losing weight. The challenge is to let leptin do its job so that the brain demands less food. When you lose some weight, your cells become more sensitive and responsive to leptin. Enough with the analogies! Annoying yet useful. Get the same information from reading Self Magazine or Prevention without the annoying constant analogies.
This was packed with interesting information. They make it easy to understand how your body works. The book has good illustrations of it.
After hearing this, you won't want to eat any "bad" food. They alternate reading the book. One of the readers does not pronounce his words clearly. I found his voice very irritating. I was not impressed with the content and, quite frankly, did not believe all they had to say. Their other book You the Owners Manual was much better.
I enjoyed listening and got a lot of useful information, but I suggest buying the book for the complete diet and exercise illustrations.
