Query: Derivative and very disappointing.

This book is a total rehash of information that anyone with a weight problem who has attempted to do anything about it would already know. The book is repetitive and tedious. You must wade through 150+ of obvious information before the unoriginal diet plan is presented. The one redeeming aspect of the book is the excercise suggestion. There are useful tips on getting started excercising and a well-structured body sculpting program using free weights. But this alone is not worth the price of the book.
