Book Description: Diet and nutrition expert Dr. Barbara Rolls and award-winning journalist Robert A. Barnett deliver a scientifically based plan that gives everyone what they've always wanted: a way to lose weight while still feeling satisfied. Emphasizing the difference between high-energy dense foods (including pretzels and other low-fat snack foods that are easy to overeat) and low-energy dense foods (like fruits and vegetables, soups and smoothies, which have a higher water content), Rolls and Barnett show readers how to increase food volume without adding calories. This is the core concept in a book that offers a systematic new approach to weight control based on the science of satiety, the study of hunger, and its satisfaction. Effective and easy, here, at last, is a real lifetime approach to eating healthy fully!
