PHILADELPHIA, Pennsylvania (AP) -- A review of 10 of the nation's most popular weight-loss programs found that except for Weight Watchers, none of them offer proof that they actually work at helping people shed pounds and keep them off.
Only Weight Watchers had strong documentation that it worked -- with one study showing that participants lost around 5 percent (about 10 pounds) of their initial weight in six months and kept off about half of it two years later.
However, the researchers who conducted the review published in Tuesday's Annals of Internal Medicine stressed that the lack of scientific evidence should not be viewed as an attack on diet programs.
Obesity is merely a symptom of an underlying issue. The problem with most, if not all, weight loss programs is that they only deal with the symptom (too much weight) and not the real problem. As a result, these findings are not all that surprising.
