Discontinuing glucagon‐like peptide‐1 receptor agonists and body habitus: A systematic review and meta‐analysis
Abstract
Research on Glucagon‐like peptide 1 receptor agonist (GLP‐1RA) has mainly focused on the efficacy of weight loss and not the long‐term efficacy of weight loss maintenance. This systematic review and meta‐analysis aims to evaluate the sustainability of weight loss of patients taking GLP‐1RAs following the discontinuation of the drug. EBSCOhost was used to simultaneously search Academic Search Premier, CINHAL Ultimate, Cochrane Central Register of Controlled Trials, MEDLINE with full text, Cochrane Database of Systematic Reviews, and separate PubMed search was systematically investigated using a predetermined search strategy from inception to February 1st, 2024. The authors extracted data regarding body weight change from baseline on treatment and off treatment, change in waist circumference from baseline on and off treatment, and change in BMI from baseline on and off treatment. Meta‐analysis was conducted using RevMan (version 5.4) to calculate pooled mean differences using a Der Simonian‐Laird Random Effects model. ResultsThe initial search yielded 497 relevant articles and, after screening, retained 8 randomized controlled trials comprised of 2372 participants, all with a BMI ≥ 27 kg/m2. After discontinuing GLP‐1RA therapy, weight regain was proportional to the original weight loss. Participants who took liraglutide regained 2.20 kg (95% CI 1.69 to 2.70, P < 0.00001), and participants taking semaglutide/tirzepatide regained 9.69 kg (95% CI 5.78 to 13.60, P < 0.00001). This…
