The Diamonds explain that body functions have a daily cycle: noon to 8 p.m.-- appropriation (eating and digestion); 8 p.m. to 4 a.m.--assimilation (absorption and use); 4 a.m. to noon--elimination (of body wastes and food debris). Fit for Life aims to return you to a lifestyle based on your natural body cycles. That means 70 percent of your diet should be "high-water-content foods"--fruits and vegetables--which facilitate all body functions. Consume nothing but fruit or fruit juice until noon, then eat salad and vegetables with every meal for the rest of the day.
Two-thirds of the book is explanation and discussion; one-third is menu plans and recipes. You won't be hungry, your food choices will be healthy, and you'll lose weight without dieting. --Joan Price --This text refers to the Hardcover edition.
