GLP-1 receptor agonists (GLP-1 RAs) promote weight loss and improve glycemic control through multiple mechanisms including increased satiety, slowed gastric emptying, and enhanced insulin secretion, with semaglutide 2.4 mg showing the highest efficacy.

GLP-1 receptor agonists like semaglutide are highly effective for weight loss and blood sugar control. Semaglutide 2.4 mg taken once weekly (either orally or by injection) resulted in an average loss of 15.3 kg over 68 weeks in clinical trials. This is significantly more effective than placebo. These drugs work by increasing satiety, slowing digestion, and improving insulin function. They are suitable for adults with obesity or type 2 diabetes.

GoodSupportsHIGH confidence
GLP-1 receptor agonists (GLP-1 RAs) are a new class of antihyperglycemic drugs that enhance appropriate pancreatic β-cell secretion, pancreatic α-cell (glucagon) suppression, decrease liver glucose production, increase satiety through their action on the central nervous system, slow gastric emptying time, and increase insulin action on peripheral tissue. ... semaglutide in higher doses promotes weight loss and can be used as a drug to treat obesity.
