What hormones does Mounjaro mimic or influence?

Mounjaro works for weight loss by mimicking two natural hormones in the body—GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide)—which both help control appetite by sending signals to the brain’s hunger centre, the hypothalamus, making you feel less hungry and more satisfied with smaller meals. By acting like these hormones, Mounjaro not only reduces your desire to eat but also slows down how quickly your stomach empties, so you feel full for longer after eating. This dual action helps create a calorie deficit, which is key for losing weight, and may also improve how your body handles insulin, though its main role in weight loss is through appetite control.

• Mounjaro mimics GLP-1 and GIP, two hormones involved in appetite regulation.
• These hormones signal the brain to reduce hunger and increase feelings of fullness.
• Slower stomach emptying means you stay satisfied longer, helping you eat less.
• Improved insulin regulation may occur, but appetite control is the main way Mounjaro aids weight loss.
