I bought 3 books on this subject this week, and this is the one I wish I hadn't bought. I am so disappointed in this book. I was expecting a true workbook, and there is no real plan in this book. There is a lot of interesting information, some of which is useful, but if I hadn't also bought The Seven Secrets of Slim People, I wouldn't have gotten a plan to actually do the work I need to do to be able to find out when I'm hungry and when I need to stop eating.
