Barbara Rolls, PhD, and co-author Robert Barnett present Volumetrics, a long-term, sensible approach to weight loss based on the breakthrough concept that you can feel full while eating fewer calories. With Volumetrics, leading nutritionist Barbara Rolls, PhD, has devised a plan to give people what they2ve always wanted: a way to lose weight while still feeling full and satisfied. By concentrating on energy density (the amount of calories in a given volume of food) and its relation to feeling replete, Rolls and co-author Bob Barnett guide the reader towards a more rewarding and manageable lifetime approach to eating - one that doesn2t include deprivation. Unlike many fad diets, their ideas are based on a solid body of scientific research, revealing the many factors that determine how much we eat, and hence how much weight we gain. From this research, Rolls and Barnett have created a clear program with tasty recipes, menus, and eating recommendations that can help anyone lose weight safely and effectively.Rolls, Barbara is the author of 'Volumetrics Weight-Control Plan Feel Full on Fewer Calories', published 2003 under ISBN 9780380821174 and ISBN 0380821176.
