KeptGoing back on a GLP-1 after a break
- Restarting is common. In a 2026 study of more than 60,000 people, 41.5% of those who stopped a GLP-1 restarted within a year, and 58% within two years.
- Going back on is not a failure. GLP-1 use is often on and off, for reasons like cost, supply, side effects and coverage.
- How to restart (including which dose) is a decision for your prescriber. Many people restart at a lower dose.
- Keep your history. Your weight before, during and after the break tells you, and your prescriber, how you respond.
If you stopped a GLP-1 and are now going back on, you're in good company. Use of these medicines turns out to be far more on-and-off than most people assumed.
How common restarting is
Researchers presenting at ENDO 2026 looked at insurance claims for more than 60,000 adults who started a GLP-1. About 4 in 10 had stopped within a year. Of those who stopped, 41.5% restarted within a year and 58% within two years. In the study's words, use is "more start-and-stop than most people assumed".
What to expect
- Your prescriber decides the restart dose. After a break, many people go back on at a lower dose rather than where they left off, because side effects can return. Don't restart at your old dose without talking to them.
- Appetite usually settles again. Many people notice food noise quieting within the first weeks back on.
- The weight you regained during the break may come off more slowly at first. Give it a few weeks before judging.
How to track a restart
- Don't start a new log. Keep your whole history: before the medicine, your lowest point, the break and now. The pattern is useful information.
- Mark the restart date. It makes the effect of each phase easy to see.
- Set a goal for this phase. For many people, it's getting back to their previous low and then holding it.
- Plan for the next change now. If you might step down, switch or stop again later, decide now what you'll watch and where your line is.
Kept has a "Back on" mode: your history stays, the restart becomes a new phase on your chart, and Kept % carries on from your original loss.
Common questions
Is it normal to go back on a GLP-1 after stopping?
Yes. In a 2026 study of more than 60,000 people, 41.5% of those who stopped restarted within a year and 58% within two years. Cost, supply, side effects and coverage changes all lead to breaks.
Can I restart at my old dose?
Ask your prescriber. After a break, many people restart at a lower dose because side effects can come back. Kept doesn't give dosing advice.
Will I lose the weight again after restarting?
Many people do lose weight again after restarting, though results vary and the first weeks can be slower. Tracking your weekly average from the restart date shows how you're responding.
Do I have to start over in Kept if I go back on?
No. Kept keeps your full history and marks the restart as a new phase, so you can see the whole picture.
