Title: Sound advice but use with utter care
Review: I read this book and started to put in practice the author's advice. Although some of the advice is sound and the program seems to work, please be careful. For example, I tried to eat only when I was hungry, which resulted in extreme weakness and other medical problems. As a result I had to give up the program after a week, had to take two weeks off work because I felt constantly weak and fainting and couldn't start a new diet for at least one month.The only useful advice is the one to exercise more. But that's hardly new, isn't it?
