<DIV>In this authoritative, easy-to-read book, Glenn Gaesser, an exercise physiologist, challenges the conventional wisdom that excess body fat poses a danger to health. He explains that it is the fat in your diet ? not your weight ? that is harmful, and presents scientific evidence of the benefits of body fat. In addition, Gaesser presents a ?20/20 program” for achieving optimal health and metabolic fitness through 20 minutes of daily moderate exercise and a complex-carbohydrate eating plan. This edition includes a new introduction and updated research. ?Challenges the common beliefs that ?thin is best' and ?weight loss improves health.' ” ? Pat Lyons, author of Great Shape</div>
