It was years ago that I read his books, but I also found it very inspiring. I think that his ideas are the basis for a lot of "healthy eating" plans that basically believe you can change the body's chemistry by changing your eating habits. It took me a lot of years for it to sink in and be ready to make those changes.
I am currently doing something similar and have to say that it works for me. One of the things that depresses, or maybe a better word is saddens me, is when I see how many people struggle with cravings, going off and on a plan that may not be right for them. They all ask "where's my willpower?" I don't believe it's about willpower. I find that if I eat what my body needs in the proper balance there are no cravings. We only find that by experimenting.
You've reminded me, I think I need to find those books again!
