What I really like about this book is that the claims are backed by research. There are pages and pages of endnotes in the back of the book that reference the studies -- from reputable sources such as the Journal of the American Medical Assoc., and Harvard.
I am a 40 year old, type II diabetic with high blood pressure. I have now been on the diet for 2 weeks and my sugar levels are under very good control. I have also lost 8 pounds. (I haven't yet checked the blood pressure)
Another positive is that this diet isn't so restrictive that you can't stay on it. It is a common sense, practical approach to eating and exercise. I don't have to give up coffee, wine, and even the occasional beer or two. Also, it's ok to cheat on occasion.
The back of the book is loaded with recipes. The publisher info listed above says 280 pages, but my book is 378 pages. The cover looks exactly the same, so maybe the 280 is a typo.
Anyway, if you are looking for a good approach to eating, getting healthy and losing weight, buy this book.
