Forget the fad diets. Stop counting carbs. Dr. Mehmet Oz has teamed up with Dr. Michael Roizen to develop a diet plan that they say really works.

Dr. Oz and Dr. Roizen have already helped millions live longer, look younger and become smarter patients. Now, they want to teach you how to lose weight and waist once and for all. The goal is to shrink your waist down to the ideal size—32 and a half inches for women and 35 inches for men—and make eating so easy, you never realize you're dieting!

In the book YOU: On a Diet, Dr. Oz and Dr. Roizen explain why the body stores blubber and how cutting just 100 calories a day can help you lose a pound per month!

Dr. Oz and Dr. Roizen studied people who lost weight and kept it off. They noticed that dieters who cut 400 calories a day ended up yo-yo dieting and regaining weight. Fasting shuts down your metabolism, Dr. Oz says, so when you bow to temptation and devour a candy bar, most of the calories are quickly deposited as fat.

Cutting 100 calories a day—the equivalent of a Granny Smith apple—is a dieting strategy that most people can sustain for a lifetime, he says.
