Psychologist and nutritionist Roberts has spent years analyzing why most diets don't work. He started by asking the simple question: What makes us feel hungry in the first place? After scouring the scientific literature and testing various theories and practices, he hit upon a strategy for controlling the body's internal "set point"--that is, the thermostat that controls weight gain or loss. The solution was counterintuitive: by taking two daily servings of either extra-light olive oil or plain sugar water, he took control of his appetite. He lost 35 pounds in three months, and has kept it off for five years. Since then, others have replicated these results. This book includes specific instructions for tailoring the program for individual needs and goals, as well as expert tips, variations, success stories, and an explanation of how Roberts devised the diet and why it works so well.--From publisher description.
