What happens if I stop my GLP-1?

Your appetite may get louder again. If it does, that is biology returning to the conversation—not evidence that you suddenly forgot everything you learned.

Weight regain is common after stopping, although the amount varies. If the medication also treats diabetes or another condition, stopping can affect more than weight. Make the plan with your prescriber before the supply runs out when possible.

What the often-quoted study actually found

In the STEP 1 extension, participants regained about two-thirds of the weight they had lost in the year after semaglutide was stopped. Structured lifestyle support also ended, and this was a follow-up subset of the original trial. The result is a reason to plan support, not a prophecy that every person will have the same experience.

Build the landing before the jump

Discuss why you’re stopping: cost, side effects, pregnancy plans, preference, or something else. The reason affects the options. Ask about alternatives, follow-up, what health measures to monitor, and when a change should trigger another appointment.

Keep meals regular, preserve a strength routine you can sustain, and arrange nutrition support if helpful. A 2021 randomized trial found that exercise combined with liraglutide supported weight-loss maintenance better than either alone after a low-calorie diet. It supports exercise as part of care; it does not prove exercise will prevent all regain after every GLP-1 is stopped.

There is no established taper that guarantees avoiding regain. Don’t invent your own spacing or partial-dose plan based on social media.

And if weight comes back? Contact your care team early. You deserve another plan, not a lecture.
