After reading about this book on Amazon I checked it out of the library to see what I thought. The science seems sound enough but there is not much information in the book that isn't already online. Most of the book consists of 75 suggested recipes ( with photos ) and while the layout is nice there is a lot of white space. I am going to try the author's eating plan and see if it helps but my advice would be to borrow this book before buying to see if it is worth the money for you.
