GLP-1 (glucagon-like peptide-1) receptor agonists are a class of FDA-approved medications originally developed for type 2 diabetes management. These medications work by mimicking the GLP-1 hormone, which plays a key role in appetite regulation, blood sugar control, and metabolic function.
When used for weight management, GLP-1 medications help reduce hunger, increase feelings of fullness, and slow gastric emptying—making it easier to consume fewer calories without constant restriction. Combined with lifestyle modifications, GLP-1 therapy has been shown to produce meaningful, sustained weight loss in clinical settings.
