Weight Watchers, Jenny Craig get high marks in diet review
Posted April 6, 2015
A review of research on commercial diets gives high marks to Weight Watchers and Jenny Craig. Those programs have good evidence of lasting weight loss, but the researchers say many other plans just haven't been studied enough to draw conclusions.
They pooled results from several studies and found that Weight Watchers dieters lost an average of at least 8 pounds and kept it off for at least 12 months. That compares with about 15 pounds for Jenny Craig.
Most participants remained overweight. Even so, their weight loss was in a range that doctors typically recommend for benefits including lower blood pressure and cholesterol levels.
The study was published Monday in Annals of Internal Medicine.
