How would you like to have a great body-the kind of body you never dreamed you could have?

If that sounds inviting, then this book is required reading. The fitness and fat-loss program outlined here will show you how to change your body composition, radically. What is body composition? It's the ratio of lean body mass to fat mass, and as you can well imagine, it's lean body mass you want. Moreover, Body Rx can teach you how to burn off fat without depleting lean body tissue. Other diets chew up the beneficial parts of the body in order to bring about weight loss

I've devoted the past three decades of my life to the science of metabolism. From my earliest days studying and researching at Harvard and Stanford, I've been investigating how the human body uses nutrients. I've studied how we make fat, how we burn fat, how we make muscle, and how we stay in shape. I've put my research to work in the intensive care unit, helping dreadfully ill patients return to health. And I've put my research to work also helping elite athletes, bodybuilders, and the fitness-conscious achieve peak performance. And now you can put it to work for yourself.

Before you dive into this program, here are some tips to make the Body Rx 6- Pack Prescription work for you

• Don't count calories. I know you've heard that before, but this program is not about calorie deprivation. On my program you'll probably be eating more calories than you ever have eaten before. And you'll be eating satisfying foods like dairy, meats, fruits, and vegetables.
 

• Get off the treadmill. My exercise philosophy revolves around strength training. You get all the benefits-even the healthy-heart benefits-of aerobics from strength training, in addition to a lean, sculpted body that is impossible to achieve on aerobics
 

• Tailor this program to fit your needs. I've set up my program to work for you even if you follow only part of it. While I love exercise (1 am as comfortable in the weight room as I am in the operating room), I have to.level with you: You can get seventy percent of the benefitof the Body Rx 6- Pack Prescription from the nutrition program alone. If you know right now that there is no way you will ever step into a gym, don't even bother to read the chapters on exercise. Instead, read the chapters on nutrition two or three times.
 

• A note to women: Our culture bombards you with destructive messages. Obsessive calorie counting, endless aerobics, and insane dieting advice have contributed to an epidemic of obesity. Women must pay attention to muscle and metabolism and startthinking differently about their bodies.

Even if you listen to nothing else, listen to me on fructose. Over the past twenty years, the degeneration of our food supply brought on by industrialization has dramatically accelerated. As the obesity epidemic grows, the changes that have been made in our food supply have outpaced our ability to adapt metabolically. While it is tempting to blame a sedentary life or out-of-control eating habits, the truth is simpler. Our eating behavior has remained basically the same. So what's the problem? The food supply is no longer appropriate for our bodies. I believe the key problem is a ubiquitous additive that has invaded our food supply over the past two decades: fructose. Even if you listen to nothing else I say, read and reread the fructose chapter. The tiny changes it recommends will make a huge difference to your body composition.

As a physician, I had the responsibility to save the lives of patients in my care. As I expanded my work out of the hospital and into the world at large, my mission grew. I discovered that the lives I can save in the operating room are just a fraction of those I can save in the world at large. I'm a metabolism scientist with one foot in the medical world and one in the weight room. I want to teach you what I've learned from both arenas. As a physician, I'm going to offer you a prescription for optimum nutrition. As your trainer, I'm going to whip you into shape. As a result, you're going to have the body you never dreamed you could have.
