There is a lot of useful information in this book, but I agree that this is a rehash of the "Neanderthin" plan. Everything was going along well until I got to the recipes and eating plans. Gimme a break! Not practical at all unless you're single or the whole family gets on board, because there's some strange stuff here. If you're prepared to double your grocery bill at health and specialty food stores, go for it. My traditional family would be willing to make a few concessions, but hitting the ground running with this book would get me banned from the kitchen...
