How the pen affects your appetite

Updated Jul 18, 2026

Semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro) mimic hormones your gut already produces after you eat. They do three things at once: they send satiety signals to the brain, curb hunger, and slow gastric emptying. That’s why you start feeling done with food sooner, feel satisfied with less, and don’t get that random urge to eat.

This is a tool, not a switch. What you eat and how you train during these weeks determines whether the weight you lose is fat or muscle too. That’s where Vivi comes in: tracking your protein, workouts, and side effects with you.

This is information to help you understand what you’re going through, and it does not replace your doctor. Only they can adjust the pen, the dose, and the treatment plan.
