The secret of dieting is provided by the author on pages 159 and 160 -1. "There is one thing that ... significantly extends our life span, and causes us to lose weight. What is it? Calorie restriction!"2. "Besides eating breakfast, exercise is the only thing that has been correlated with long-term, sustained weight loss."Those are not the words of a cynical reviewer. Those are direct quotes from the author. If you have never read a diet book and have no clue what comprises a healthy diet, then this book may be of some help. Otherwise, there is nothing new and some dubious suggestions backed by zero scientific research. Rather, they are presented as, "comprehensive medical and clinical perspectives". I also reserve a healthy dose of scepticism for any book presenting a note from the author that impies there is a vast medical, government and food industry conspiracy to keep us ignorant while only the author is prepared to reveal this "hidden knowledge".
