I was fairly disappointed in this book. I am a vegan and was interested in endurance sports nutrition so this book should have been an easy sell. For me, however, there were three major flaws with this book. First Brazier makes some really sweeping statements about health and nutrition with little if any scientific references or support of the statements. I kept hoping for footnotes evidencing support for these broad statements but most often there were none. For example, he really hammers cortisol as a central theme of weight gain but lacks or fails to provide much, if any scientific evidence supporting his claim. It seemed to me too many of his claims are supported simply by the fact it worked for him. A study of one (him!) really isn't great science! Second, too many times he relies on information from his first book without anything more than saying, "You will find that covered in my first book" or something along those lines. Basically then if you want to understand a point he is making you have to buy the first book. Finally, and the biggest flaw for me is that many of his nutritional recommendations are simply based on having to buy his products he is selling. His product just happens to be a key ingredient in many of his recipes. The whole book reads like a cheap infomercial for his first book and his expensive food supplements/products. I should even add, that I have used his products and they are fine, but I don't appreciate the book's covert attempt to sell them! Further, based on how little evidence he provides in his book, I am a lot less likely to continue buying his products! In conclusion, if you are looking for a solid book on nutrition for vegan athletes this doesn't seem to be it!
