What is a GLP-1 agonist?

A GLP-1 agonist (GLP-1 receptor agonist) is a class of medications that mimic the GLP-1 (glucagon-like peptide-1) hormone naturally produced in your gut after eating. These medications have transformed weight loss treatment, producing 15-22% body weight loss — results previously only achievable with bariatric surgery. GLP-1 agonists are FDA-approved for both type 2 diabetes and chronic weight management.

How do GLP-1 agonists work?

GLP-1 agonists work through multiple mechanisms simultaneously:

  • Appetite suppression — Activate GLP-1 receptors in the hypothalamus, reducing hunger and increasing fullness
  • Delayed gastric emptying — Slow the rate at which food leaves the stomach, prolonging satiety
  • Insulin stimulation — Boost insulin release when blood sugar is high (helpful for diabetes)
  • Glucagon suppression — Reduce glucagon production, preventing excess glucose release from the liver
  • Reduced food noise — Many patients report a dramatic decrease in constant thoughts about food

GLP-1 vs dual agonists vs triple agonists

GLP-1 agonists are evolving rapidly. Here's the current landscape:

  • GLP-1 agonists — Target only the GLP-1 receptor. Examples: semaglutide, liraglutide, dulaglutide. Up to 15% weight loss.
  • Dual agonists (GLP-1/GIP) — Target both GLP-1 and GIP receptors. Example: tirzepatide (Zepbound, Mounjaro). Up to 22.5% weight loss. See our semaglutide vs tirzepatide comparison.
  • Triple agonists (GLP-1/GIP/glucagon) — Target three receptors. Examples: retatrutide (in development). Expected to produce 25%+ weight loss. See our retatrutide guide.
