What people really need to do, they need to know the truth about what do you need to know about physiology? What do you need to know about dieting? What do you need to know about nutrition? That's what I put in the book. First, as I introduce things, I point out these diet programs and supplements are really bogus. I can give you a little bit on that and what you really need to know. I go through the physiology, nutrition, things that you need to know, and it's written for a layman.
