Well, I ordered and have been reading "The Fat Switch" by Dr. Richard Johnson. This is a really good read. It isn't simply a diet book. Johnson goes into Natural History about human evolution and comparative studies to other animals. The book then goes into how sugar (and honey too) into different societies (pre BC and New World sugar trade) that then report medical literature from those cultures about obesity and diabetes. Merocal is spot on that the book reads like a novel detective story.
Would I be putting a grain-feed cow on a fad diet if I took it out of the feedlot and put it on pasture eating the grass nature intended?
