GLP-1 receptor agonists (semaglutide, liraglutide, tirzepatide) produce significant weight loss (6.2–15.8 kg) in adults with obesity, with efficacy increasing with higher doses.

GLP-1 agonists like semaglutide and liraglutide are effective for significant weight loss in adults with obesity, often outperforming lifestyle changes alone. Expect weight loss between 6-16 kg over several months. Be aware of gastrointestinal side effects, which are common but often manageable. These are prescription medications requiring medical supervision to manage dosing and side effects.

GoodSupportsHIGH confidence
The results of such studies indicate that treatment with semaglutide, liraglutide and tirzepatide is particularly effective in terms of weight loss, with a loss of 6.2 kg to 15.8 kg over 16 to 68 weeks of treatment.
