Query: Another DIET book...when will we learn?

Roizen helps people learn how their body works and how to get in touch with it. The criticism I have of the book is that he advocates a special diet, rather than focusing on what your body tells you it needs. Another book "The Overfed Head" by Rob Stevens shows you how to do that with the goal of losing weight. I think the information from Roizen and the knowledge from Rob Stevens would be the perfect combination to lose weight and be healthy and feel great....so check out "The Overfed Head" in addition to this book.....I lost 15 pounds in one month without any sort of diet and have kept it off! Dieting only works while you are on the diet.
