There are some reviews on Amazon. I also found the author's blog, which looks like it has a lot of the same information that is found in the book.

Looks like it's another spin on the intuitive eating idea. Might have some good ideas, but I'd definitely not spend $14.99. But if you can get it for .99, why not?
