“A must-read for anyone who has struggled to maintain a healthy weight.”

“Dr. Ludwig brings a fresh and welcome perspective, based on his extensive clinical and research experience, to the challenges facing millions of overweight Americans. Until now, most attempts at weight loss have focused primarily on calories consumed and burned, but what seems right in theory often fails in practice. Dr. Ludwig explains why throwing out our calorie-counters and paying more attention to the quality of our diets can result in a healthier weight, and to more enjoyment from eating at the same time. This is a must- read for anyone who has struggled to maintain a healthy weight.”
