The best part about this book is that it can suit nearly anyone wanting to lose weight; it allows you to "customize" your own weight loss program that is particulary tailored to fit your needs. I purchased this book for my mother, drawn in by the astounding figures it produced in the first edition. Not only did my mom's appearance improve, but it also increased her overall well-being. Because she is a caterer, she is constantly stressed out because of the "up and go" type of work she does. She claimed that after three months of being on the program, her days seemed to be much "lighter!" The days seemed to go by quicker and with less stress. Any book that can do those two major things is worth looking into.
