Most weight lost on GLP-1 obesity drugs returns within a year, study finds
A meta-analysis of six randomized trials (3,200+ participants) shows people rapidly regain about 60% of the weight lost during GLP-1 class obesity treatments within a year of stopping, with long-term modelling suggesting regain may plateau after around 60 weeks and reach roughly 75% of the lost weight. The studies raise uncertainty about whether regained weight is lean mass or fat, and they underscore the potential need for tapering doses and lifestyle support to preserve fat loss after cessation.
