Hormonal

GLP-1 receptor agonists (GLP-1RAs) treat obesity by activating central and peripheral GLP-1 receptors to increase satiety, delay gastric emptying, and modulate energy expenditure, resulting in significant weight loss.

GLP-1 receptor agonists are a class of medications that mimic a gut hormone to signal fullness to the brain and slow digestion. They are prescribed for obesity and type 2 diabetes. Common examples include Semaglutide (Ozempic/Wegovy) and Liraglutide (Saxenda). These drugs require a prescription and often involve starting at a low dose to manage side effects like nausea. They are part of a long-term management strategy for obesity, not a quick fix.

GoodSupportsHIGH confidence
GLP-1R agonists have a hypoglycemic effect second only to insulin and have the advantages of low risk of hypoglycemia, significant weight loss effect, and cardiovascular benefits... GLP-1 from the gut can also transmit information upward to the central nervous system via the vagus nerve, which in turn inhibits vagus activity and stomach emptying, increasing satiety.

Why this rating

The paper reviews multiple approved drugs (Semaglutide, Liraglutide, Tirzepatide) with clinical trial data, though it is a review rather than a single primary RCT.
