The short answer. Plan for some regain. Roughly 60% of the weight lost on GLP-1s can come back within a year of stopping, and it tends to return as fat. What you can change is how far the number moves and what it's made of: keep protein intake high and resistance training consistent, while measuring fat and muscle (not just weight).
Stopping is a decision to make with your prescriber. This isn't about whether or when to stop, or how to taper your dose. It's about what you can do around that decision, so the progress you worked for is the progress you keep.
How much weight comes back after stopping a GLP-1?
More than most people expect. A 2026 analysis found that roughly 60% of the weight lost on GLP-1s can come back within a year of stopping, with regain projected to level off near 75%. In one trial, most people who switched to a placebo regained a quarter or more of what they had lost.
Some regain is normal, and pretending otherwise doesn't help. The hunger the medication was quieting comes back, and your body has spent months (or years) eating less. Expect the number to move. The real questions are how far, and what it's made of.

What does the weight come back as?
Mostly fat. Researchers report that regained weight is primarily fat, not the muscle that was lost.
The pattern is older than any of these medications. After a study of rapid weight loss in the 1940s, researchers documented that fat returned first and overshot its original level before lean tissue rebuilt. Later analysis found the same fat-first pattern across both loss and regain.
Same number on the scale, completely different bodies. Three pounds of fat settling onto a frame carrying less muscle is not the same as three pounds of muscle added on purpose. A regular scale can't tell them apart.

Why does muscle matter for keeping it off?
Muscle is one of the biggest drivers of metabolism. Keeping it and building it back are the highest-leverage moves you can make to combat the rebound. That's why the work starts before the last dose.
What to do before your last dose
- Talk to your prescriber about the plan. How and when to stop is their call, made with you. Everything below supports it.
- Take a starting measurement. Record your weight, body fat and muscle before you stop, so you can see what changes afterward instead of guessing.
- Lock in the protein habit while appetite is still quiet. Three protein anchors a day is far easier to keep once it's already routine. Here's how much protein you need on a GLP-1.
- Keep resistance training going, or start it now. It doesn't need a gym. Sessions at home are enough to protect your muscle.
What to do after you stop
- Expect hunger to come back, and plan for it. When the medication stops, the job it was doing, quieting hunger, transfers to you. Regular meals built around protein make that easier than willpower alone.
- Keep protein and training steady. They're the two habits the medical advisories recommend, and they matter most now.
- Measure the same way every morning and read the weekly average. Daily readings wobble. The four-week trend is what you act on.
- Watch what the number is made of, not just the number. A creeping weight with muscle holding is a very different picture from a creeping weight with body fat rising.
What to watch on the scale
Weight up, muscle up, body fat % steady or down
Usually means: Some of the gain is muscle you're building.
What to do: Keep going.
Weight up, body fat % up, muscle flat or down
Usually means: The regain is mostly fat.
What to do: Look at protein and training first, and talk to your prescriber if it keeps climbing.
Weight steady, body fat % down
Usually means: Your body is changing while the scale stands still.
What to do: Keep going. The scale is the wrong judge here.
One heavy week, then back to normal
Usually means: Usually water.
What to do: Ignore it and read the trend.
A trend isn't a diagnosis. It's a reason to act, or a reason to keep going.
Where Orvi fits
Orvi was built for the whole arc, including the step-down. The Orvi Protect & Grow System runs in order: the Protect System's protein target and home sessions while the weight comes off, then the Grow System's gym plan once it settles, with a review every 4 weeks that ends in one decision. Stepping down, the Grow System's last chapter, is written for the day a dose decision arrives. It never sets or alters a dose; that's your prescriber's decision. It supports what your prescriber decides; it doesn't replace their guidance.
Same number, completely different bodies. The Orvi Body Scan is how you tell them apart.
