The Gravity of Weight" is the most thorough and scholarly volume on the problems of weight gain and its control that I know of. The authors skillfully guide the reader through an explanation of the role of calories and the description of the neurophysiology and psychology relevant to obesity. They conclude with an enlightened survey of the various approaches to weight control, including surgical treatments. Aaron T. Beck, M.D., University Professor Emeritus of Psychiatry, University of Pennsylvania The Gravity of Weight nails down the top thinking and latest clinical research on weight loss and maintenance. It illuminates the physiological factors of weight loss and weight gain, doing so in a punchy, complete, no-nonsense manner. In addition to being an in-depth reference, its use of sidebars and call-outs make it an invaluable handbook for the busy clinician. This is a must-have guide for professionals who want to be serious and successful with their patients' weight loss. Brian Wansink, Ph.D., Author of Mindless Eating: Why We Eat More Than We Think
