I'm going to step on a few toes here, but I read Bragg's book and I think he's a nut. He can't complete a thought without jumping off to some other aspect of fasting. The book is a hodge-podge of feel-good anecdote.
There is plenty of great reading that can be downloaded for free, such as Shelton's book on the Soil and Health website.
You are going to benefit greatly from fasting if you can discipline yourself to do it correctly.
