Seven glucagon-like peptide-1 receptor agonists and polyagonists for weight loss in patients with obesity or overweight: an updated systematic review and network meta-analysis of randomized controlled trials

Conclusion: Retatrutide (both doses) and tirzepatide exhibited superior efficacy compared to other GLP-1 receptor agonists and polyagonists in reducing body weight and waist circumference. Patients without T2DM, those with a high BMI, and individuals undergoing longer treatment cycles demonstrated significantly greater weight loss and reductions in waist circumference. Dual or triple receptor agonists (GLP-1 plus glucose-dependent insulinotropic polypeptide and/or Glucagon receptor) are more effective for weight loss than GLP-1 receptor agonists.
