Query: Very Informative!

I am very impressed with this book. It is very informative and is suitable for people of all shapes and sizes. It is geared towards people who have a problem with weight; however, I do not have a problem with weight, but still have learned plenty from the book. Bob Greene is very knowledgeable and Oprah speaks from personal experience. It is written in simple english with very few technical terms, however the technical aspects of weight loss are still discussed. I find this book very motivating and would recommend it for anyone who is interested in healthy living!
