Abstract

BackgroundObesity is common in the U.S. and many individuals turn to commercial programs to lose weight. Our objective was to directly compare weight loss, waist circumference, and systolic and diastolic blood pressure SBP, DBP outcomes between commercially available weight-loss programs.

MethodsWe conducted a systematic review by searching MEDLINE and the Cochrane Database of Systematic Reviews from inception to November 2014 and by using references identified by commercial programs. We included randomized, controlled trials RCTs of at least 12 weeks duration that reported comparisons with other commercial weight-loss programs. Two reviewers extracted information on mean change in weight, waist circumference, SBP and DBP and assessed risk of bias.

ResultsWe included seven articles representing three RCTs. Curves participants lost 1.8 kg 95%CI: 0.1, 3.5 kg more than Weight Watchers in one comparison. There was no statistically significant difference in waist circumference change among the included programs. The mean reduction in SBP for SlimFast participants was 4.5 mmHg 95%CI: 0.4, 8.6 mmHg more than that of Atkins participants in one comparison. There was no significant difference in mean DBP changes among programs.

ConclusionsThere is limited evidence that any one of the commercial weight-loss programs has superior results for mean weight change, mean waist circumference change, or mean blood pressure change.
