The Zero Calorie Diet - How To Eat Right -Or Not At All Is a book about fasting - about eating, not eating, eating less, and about the commercialization of food - and everything else -- in our bloated culture. Written by a family doctor, The Zero Calorie Diet examines the physiology of fasting and nutrition, so everyone can understand how much food the body really needs, what stimulates hunger, and how not to eat, even in a world where calories are everywhere.
