Diets, Diet book Ratings 06/07
Diet books What the experts sayThese seven diet books have never been put to the acid test of a large clinical trial (unlike the diet plan Ratings). We rated them based on an expert-panel questionnaire and our own analysis of nutritional quality.Books are listed in rank order of overall score. Scores of “Eat, Drink, & Weigh Less,” “You on a Diet,” and “The Abs Diet” were very close to one another.All the books offered fairly healthful menus. But when our panelists evaluated the nutrition advice, they found noticeable differences in the restrictiveness of various books. They also found variations in the quality of exercise information and the explanations of the science and nutrition behind the plans.Our nutritional analysis is based on the 2005 U.S. Dietary Guidelines for Americans. The guidelines are updated every five years and represent a broad scientific consensus. THE BEST LIFE DIET Bob Greene (Simon & Schuster) $26 What it is The diet's first phase involves exercise and a recommended eating schedule. Calorie reduction starts in phase two. You eat enough healthful foods to satisfy hunger but no more. Includes tools to customize diet and exercise plans.Pros and cons Reviewers liked personalized advice and section on exercise. Extensive discussion of "emotional eating" might help some. Dieters might be discouraged when they don't lose weight in phase one. Straightforward recipes use common ingredients.

Premise is that by “mindfully” following this diet, you can lose weight while enjoying eating. Little full-fat dairy or red meat. Up to one egg and one glass of wine a day.Pros and cons Sample diet had 1,910 calories per day--too many to allow most people to lose weight.

Roizen, M.D., and Mehmet C. Oz, M.D. (Simon & Schuster) $25 What it is The physician-authors devote more than half the book to background on appetite, metabolism, and behavior. Diet starts with a two-week “rebooting program.” Monotonous breakfasts and lunches cut down cravings. Sugar, saturated fat, and refined flour products are banned.Pros and cons Most reviewers thought the diet lacked detail and was too restrictive, and some were skeptical that habits can change for good in two weeks. Most recipes were very simple. Rating Overall score............... Expert evaluation Science............... Nutrition............. Exercise............. Ease of use.............

Includes about 100 pages of illustrated exercises.Pros and cons Reviewers were skeptical of the promise of rapid weight loss and disliked emphasis on whey supplements. Fitness program deemed easy to follow but possibly too strenuous for beginners and more appealing to men. Rating Overall score............... Expert evaluation Science...............

In the first phase, fruits, sugar, and grains are banned. Phase two allows some fruit, high-fiber grains, and dark chocolate.Pros and cons Reviewers thought the simplicity of diet would appeal to some but criticized overuse of the glycemic index and the too-short exercise section. Recipes seemed easy to prepare, but some called for unusual ingredients. Rating Overall score............... Expert evaluation Science............... Nutrition............. Exercise.............

The longer wave 2, where most weight loss takes place, permits fruits and wine. You calculate portions by filling sectors of small plates with specified food categories.Pros and cons Reviewers found the overall diet healthful but complex and needlessly restrictive. They felt the book stinted on exercise. Recipes were rather elaborate to prepare. Rating Overall score............... Expert evaluation Science............... Nutrition.............

Initial “detox” phase and longer “rebalancing” phase. Eliminate: white rice, refined grains, grain-fed or processed red meats, caffeinated beverages.Pros and cons Reviewers felt book’s theory goes beyond scientific evidence and was overly restrictive and complicated. Exercise section judged somewhat brief but practical. Rating Overall score............... Expert evaluation Science............... Nutrition............. Exercise.............
