Being on a diet is a miserable experience for most people, and it rarely leads to the desired goal of shedding fat. In fact, studies show that dieters often gain weight rather than lose it because most diets’ intensity, restrictions, and short duration are ill-equipped to produce long-term effects. In Smart People Don’t Diet, Dr. Charlotte N. Markey offers a refreshingly different approach to weight management.

Based on more than 100 years of research by scientists, doctors, nutritionists, and psychologists, Dr. Markey’s plan addresses the underlying causes of weight gain and offers proven strategies for healthful, lasting weight management, including advice on how to eat well, lose weight, and keep it off. The gimmicks don’t work, but Dr. Markey’s reasonable, accessible advice will help you get—and stay—healthy.

Forget fad diets: this no-gimmick, science-based, step-by-step guide written by a health psychologist provides the keys to healthy, long-term weight management.
