Hormonal

GLP-1 receptor agonists (GLP1RAs) such as semaglutide and liraglutide induce significant weight loss (5-15%) and improve metabolic markers by delaying gastric emptying, suppressing appetite via central nervous system signaling, and enhancing glucose-dependent insulin secretion.

GLP-1 medications like semaglutide and liraglutide are highly effective for weight loss (5-22%) and metabolic health. They work by slowing digestion and signaling fullness to the brain. Start with the lowest dose to minimize nausea, which usually improves over time. Combine with a calorie-controlled diet and exercise for best results. Oral versions exist but may have different absorption requirements.

GoodSupportsHIGH confidence
GLP1RAs are known to directly interact with GLP-1 receptors in the circumventricular organs of the hypothalamus, the hind-brain and certain regions of the brain adjacent to ventricles that are considered to promote satiety and weight loss... Liraglutide delays the emptying of the stomach, reduces appetite, inhibits glucagon secretion and enhances insulin secretion in a glucose-dependent manner.

Why this rating

The paper cites multiple randomized controlled trials and FDA approvals, though it is a review article summarizing existing data rather than primary trial data itself.
