Weight Watchers caused greater weight loss than a self-help program after one year (9.5 lbs vs 2.9 lbs) and after two years (6.4 lbs vs 0.4 lbs) according to a 2003 study. Subjects
Subjects: 65 men, 358 women, overweight or obese, 18-65 years-old
The study involved “overweight and obese men (n = 65) and women (n = 358) (body mass index, 27-40) aged 18 to 65 years”.
They were randomly assigned to “either a self-help program (n = 212) consisting of two 20-minute counseling sessions with a nutritionist and provision of self-help resources or to a commercial weight loss program [Weight Watchers] (n = 211) consisting of a food plan, an activity plan, and a cognitive restructuring behavior modification plan, delivered at weekly meetings.”
The study was a “A 2-year, multicenter randomized clinical trial with clinic visits at 12, 26, 52, 78, and 104 weeks conducted at 6 academic research centers in the United States between January 1998 and January 2001.”
Completers after 2 years: 71% in Weight Watchers group, 75% in self-help group
“At 2 years, 150 participants (71%) in the commercial group and 159 (75%) in the self-help group completed the study,” the paper noted.
