Although I disagree with a couple of the authors views, this book is revolutionary. I have been a student of nutrition for a few years now and this is the only book of it's kind that I have found. I have not put into practice the diet for my type as I am trying to conquer my candida issues. I will however follow this diet probably for the rest of my life. It is very straightforward and simple to follow. And the exercises are easy and energizing. One size does not fit all and this seems to be the answer. I highly recommend.
