What Are GLP-1 Medications and How Do They Work?

What Are GLP-1 Medications?

GLP-1 (glucagon-like peptide-1) receptor agonists are a class of medications originally developed for type 2 diabetes that have shown remarkable results for weight loss.

How They Work

GLP-1 medications mimic a natural hormone your body produces after eating. This hormone:

• Signals fullness to your brain, reducing appetite

• Slows stomach emptying, helping you feel satisfied longer

• Regulates blood sugar, reducing cravings

Types of GLP-1 Medications

Semaglutide (Ozempic/Wegovy class) targets GLP-1 receptors and produces an average of 15% body weight loss.

Tirzepatide (Mounjaro/Zepbound class) targets both GLP-1 AND GIP receptors, producing 20-25% average weight loss — the strongest results in clinical trials.
