You: On A Diet is part of a series of books by Michael F. Roizen, MD and Mehmet C. Oz, MD, the "You: Series". The book offer practical advise, based on the knowledge and understanding two doctors.

You: On A Diet show us the connections between all the systems in the body. The brain, stomach, muscles, hormones, heart, stress levels, and genetics all interact with each other. It's a complex biological system, but they break it down for you, so you can understand it. All of these forces work together to determine your body size and shape.

It's not just biological, but psychological. Why are so many of us overweight? Why are we unable to control our waistlines? The authors of You: On A Diet get into the hormonal and psychological reasons for our condition. They get into the "psychology of fat".

Once they've explain the background of why we are the way we are, they then present their diet and exercise program to break us out of these unhealthy cycles. By working with their knowledge of the body and mind, they have been able to come up with a plan that works.

They call it the "You diet" and "You workout". It's easy to learn, follow and maintain using their techniques. They recommend not worrying about your weight as much as your waistline.

The plan starts out with a familar 2 week startup phase. Most people are able to lose 2 inches right at the beginning of the program.
