I read this book intending to give it the benefit of the doubt. It wasn't as vapid as I thought. Barnouin and Freedman spend a good amount of time encouraging health over skinniness--though obviously if you are healthy, you will also be the proper weight and overall the book is too shallow to be of any real benefit.
The authors also pay lip service to everyone making their own choices and doing what's right for them but any actual science is clouded by their own political opinions. (If you do read it, skip the PETA driven Chapter 6). The recipes aren't bad but the science is largely outdated. Buy yourself a subsription to "Cooking Light" magazine instead. Better yet, read In Defense of Food by Michael Pollan!
