Abstract

Objective: The Centers for Medicare and Medicaid Services (CMS) covers intensive behavioral therapy (IBT) for obesity. The efficacy, however, of the specific approach has never been evaluated in a randomized trial, as described here. The 1‐year trial also assessed whether the addition to IBT of liraglutide 3.0 mg would significantly increase weight loss and whether the provision of meal replacements would add further benefit. Methods: A total of 150 adults with obesity were randomly assigned to: IBT (IBT‐alone), providing 21 counseling visits; IBT combined with liraglutide (IBT‐liraglutide); or IBT‐liraglutide combined for 12 weeks with a 1,000‐ to 1,200‐kcal/d meal‐replacement diet (Multicomponent). All participants received weekly IBT visits in month 1, every‐other‐week visits in months 2 to 6, and monthly sessions thereafter. Results: Ninety‐one percent of participants completed 1 year, at which time mean (± SEM) losses for IBT‐alone, IBT‐liraglutide, and Muticomponent participants were 6.1 ± 1.3%, 11.5 ± 1.3%, and 11.8 ± 1.3% of baseline weight, respectively. Fully 44.0%, 70.0%, and 74.0% of these participants lost ≥ 5% of weight, respectively. The liraglutide‐treated groups were superior to IBT‐alone on both outcomes. Weight loss in all three groups was associated with clinically meaningful improvements in cardiometabolic risk factors. Conclusions: The findings demonstrate the efficacy of IBT for obesity and the potential benefit of adding pharmacotherapy to this approach.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
