A new study by researchers at Johns Hopkins, published Monday in the Annals of Internal Medicine, reviewed clinical trials on some of the most popular commercial weight-loss programs, including Weight Watchers , Jenny Craig , and Nutrisystem , along with some like Medifast and OPTIFAST that promote more extreme calorie restrictions and meal replacements. Out of 4, studies, they found only a few dozen met the scientific "gold standard" of reliability.

Participants consume just to 1, calories a day on these plans, resulting in at least 4 percent more weight loss than people who got counseling alone.
