Treatment with glucagon-like peptide-1 receptor (GLP-1R) agonists (exenatide or liraglutide) at clinically relevant doses for at least 20 weeks results in significant weight loss in overweight or obese patients, regardless of type 2 diabetes status.

If you are overweight or obese, GLP-1R agonists like exenatide or liraglutide are proven to help you lose weight, even if you don't have diabetes. You take them by injection (daily or weekly), and while you might feel nauseous at first, this usually passes. The average weight loss is around 3 kg, which is clinically significant. Talk to your doctor about whether these are right for you.
