What happens when you stop GLP-1?
Medically reviewed
GLP-1s are pharmacological appetite suppressants, not metabolic resets. When the medication clears, hunger signaling and gastric emptying return toward baseline. The STEP-4 extension trial documented mean regain of about 11.6% of body weight within a year of discontinuation — roughly two-thirds of the original loss.
A planned exit (slow taper, strong protein floor, resistance training, sleep, and stress management) reduces regain. Some people stay on lower maintenance doses indefinitely; others cycle. This is a decision to make with your prescriber, not unilaterally.
