If you stop a GLP-1 medication, weight regain is common, and many people also notice more hunger and a return of “food noise” or cravings.[1][2][15][17] The amount regained varies, but randomized trials and meta-analyses show a clear rebound pattern after discontinuation.[4][7][15]
What the evidence suggests:
- In a review cited by Harvard Health, people who stopped GLP-1 obesity drugs regained nearly 1 pound per month on average, and many regained all the weight within two years.[2]
- A 2024 meta-analysis found an average regain of 5.63 kg after stopping GLP-1 receptor agonists, with worsening of blood sugar and other cardiometabolic measures.[4]
- Another systematic review reported a mean rebound of 4.13 kg after treatment withdrawal.[7]
- In trial data discussed by several sources, people stopping semaglutide regained about two-thirds of their prior weight loss within about a year.[6][12][17][18]
What you may feel after stopping:
- Increased appetite and stronger hunger cues.[1][2][6][10]
- Return of food noise and cravings.[2][10][13]
- Less feeling of fullness from normal portions.[2][10]
- In some people, higher blood sugar if the drug was being used for diabetes.[6][9][16]
- Some sources also report possible blood pressure or other cardiometabolic changes after stopping.[6][11][15]
A key nuance is that not every real-world study shows the same magnitude of regain. A 2026 Cleveland Clinic analysis found that average weight regain after stopping was not significant in their clinical practice data, likely because many patients restarted treatment or switched therapies.[3] That does not contradict the trial evidence so much as show that outcomes can differ when people continue some form of obesity treatment.[3][15]
In practical terms, GLP-1s are generally treated as long-term medications for a chronic condition, not a short course that “cures” obesity.[15][17] If you’re considering stopping, it’s worth planning with your clinician for appetite, weight, and blood sugar monitoring, plus a maintenance strategy.
