Consumer Reports have chosen the "best" diets and diet books. The Volumetrics eating plan was chosen as the best diet, and Bob Greene's Best Life Diet chosen as the best book.
This has been covered heavily in newspapers, but a closer look at the ratings criteria shows that the results are somewhat dubious.
Diet Ratings (best to worst)
Volumetrics, Weight Watchers, Jenny Craig, Slim-Fast, eDiets, The Zone Diet, Ornish Diet and, in last place, the Atkin's Diet.
To rate the diets, Consumer Reports reviewed diet studies published in major medical journals. Quite frankly, there are few comprehensive long-term studies for some of these diets. To quote a major review from Archives of Internal Medicine:
"With the exception of Weight Watchers, the evidence to support the effectiveness of major commercial weight loss programs is limited. Patients considering the use of commercial weight loss programs should realize that these programs have not been carefully studied and that they vary greatly in cost."
Diet Book Ratings (best to worst)
The Best Life Diet; Eat, Drink, & Weigh Less; You On a Diet; The Abs Diet; The South Beach Diet; The Sonoma Diet; Ultra-Metabolism.
