Using FDA regulatory data, we compared GLP-1 RAs, GLP-1/GIP dual agonists and non-GLP-1 weight loss agents, finding the greatest weight reductions with tirzepatide and liraglutide. While efficacy outcomes were favourable, safety signals were limited by small sample sizes. Expanded real-world evidence is needed to better characterize long-term safety.
Prasad et al. (2026) studied this question.
