Can thinking and eating like a thin person be learned, similar to learning to drive or use a computer? Beck (Cognitive Therapy for Challenging Problems) contends so, based on decades of work with patients who have lost pounds and maintained weight through Cognitive Behavioral Therapy (CBT). Beck's six-week program adapts CBT, a therapeutic system developed by Beck's father, Aaron, in the 1960s, to specific challenges faced by yo-yo dieters, including negative thinking, bargaining, emotional eating, bingeing, and eating out. Beck counsels readers day-by-day, introducing new elements (creating advantage response cards, choosing a diet, enlisting a diet coach, making a weight-loss graph) progressively and offering tools to help readers stay focused (writing exercises, to-do lists, ways to counter negative thoughts). There are no eating plans, calorie counts, recipes or exercises; according to Beck, any healthy diet will work if readers learn to think differently about eating and food. Beck's book is like an extended therapy session with a diet coach.
