In plain words

What the trial is, and whether it could suit you

The goal of this clinical study with research procedures is to learn how stopping and restarting tirzepatide (a medication that helps regulate blood sugar and appetite) affects brain activity, behavior, and health in adults ages 18-70 who are currently taking tirzepatide. Specifically, the study aims to examine how a short pause in tirzepatide affects hunger, mood, sleep, and daily functioning; how stopping and restarting tirzepatide alters brain chemistry and brain responses to food-related images; and how these changes relate to health measures such as quality of life and emotional well-being. There is no comparison group; instead, researchers will assess changes within each participant across three time points: while taking tirzepatide, after stopping it for 3-4 weeks, and after restarting it for 6-8 weeks. Participants will attend three in-person visits lasting approximately 3-4 hour
