Glucagon-like peptide-1 (GLP-1) receptor agonists (exenatide and liraglutide) produce statistically significant weight loss in overweight or obese patients with type 2 diabetes compared to placebo, with no significant difference in efficacy between the different GLP-1 agonists or dosages.

If you have Type 2 Diabetes and are overweight, GLP-1 receptor agonist medications (like Exenatide or Liraglutide) are clinically proven to help you lose weight compared to a placebo. The amount of weight loss is modest (around 1-1.6 kg over 6 months) but consistent across different types of these drugs. This is significant because even small weight losses can improve survival and health outcomes in diabetes. These medications are injectable and may cause temporary stomach issues, but they are more effective for weight loss than many other common diabetes drugs that cause weight gain.

GoodSupportsHIGH confidence
This review provides evidence that glucagon-like peptide-1 receptor agonist therapies are associated with weight loss in overweight or obese patients with type 2 diabetes with no difference in weight loss seen between the different types of GLP-1 receptor agonists assessed.
