There are a few editions of this book around with each containing slight differences as different diets are studied and more research results come out about diet's effect on various diseases.

Basically it's a book about the dangers of the processed food, high (bad) fat, high carb, high sugar western diet or Standard American Diet (SAD) versus a low carb diet.

Dr Bowden has a lively and well written and researched style which is easy to understand and he makes some complicated medical concepts more accessible to the layperson. The 2004 version of the book - which is the one available from openlibrary.org - contains sections on the history of low carb diets, why they work, reviews fourteen of the low carb diets from 2004 (I understand other versions have updated the diets) including the Atkins Diet, the Paleo Diet, the Scarsdale diet, the South Beach Diet and the Zone, and has chapters on diet supplements and drugs, low carb myths, frequently asked questions, tricks of the trade, and how to put a low carb program together. It also has a comprehensive and helpful index.

Definitely a book worth reading for anyone interested in getting healthier.
