The primary objective of this book is to shock the reader into becoming a Vegan. It is not a diet or weight-loss book.Just know that the co-author, Kim Barnouin, is a former model who did most of the book's "research". She lists that she has a Master of Science in Holistic Nutrition. What she doesn't say is she got the degree through the mail, from Clayton College of Natural Health, a non-accredited natural health school.So if you choose to become a Vegan due to the hormones that the put into livestock, the poor conditions that they live in, or the in-humane way that they are killed, that is perfectly understandable. But don't confuse this book with anything scientific or written by an expert on the subject, because it is not.
