Glucagon-like peptide-1 receptor agonists (GLP-1RA) such as liraglutide and semaglutide induce significantly greater weight loss and reduce hepatic fat content compared to lifestyle modification and first-generation anti-obesity drugs.

If you have obesity, Type 2 Diabetes, or fatty liver disease (MASLD), GLP-1 receptor agonists like semaglutide or liraglutide are currently the most effective pharmacological treatments for weight loss, outperforming lifestyle changes alone and older weight-loss drugs. They work by targeting brain centers to reduce appetite and also directly reduce liver fat. While they can cause side effects like nausea, their ability to improve metabolic health and liver disease makes them a superior option for many patients, though adherence to the regimen is critical.

GoodSupportsHIGH confidence
Certain GLP-1RA are superior to lifestyle modification and first-generation anti-obesity drugs in inducing weight loss. They also lead to a reduction of hepatic fat content and inflammation in people with biopsy-confirmed MASLD.

Why this rating

Based on a review of extensive literature including meta-analyses of RCTs and clinical trials, though it is a review paper rather than a single primary trial.
