What happens to your weight when you stop a GLP-1?

1 min readScience-based

GLP-1 medications work while you take them. When people stop, studies show a large share of the lost weight tends to come back. Understanding why helps you plan for it.

Why weight comes back

When the medication stops, appetite returns, so it is easy to eat more than before. If you also lost muscle on the way down, your metabolism is now lower, which means you burn fewer calories at rest. Lower burn plus higher appetite is a recipe for regain.

Muscle is your insurance

This is the practical reason to protect muscle while you lose weight, not just for how you look. More muscle means a higher resting metabolism, which makes maintaining your new weight easier when the medication is no longer doing the work for you.

  • Keep eating enough protein, even after you stop.
  • Keep training. Resistance work is what holds onto muscle long term.

The weight-loss phase is when you decide how easy maintenance will be. Muscle kept now pays off later.

Know where you stand

Check how much of your weight is lean mass with the FFMI calculator, and keep logging through and after your medication in the muscle tracker.

This guide is general wellness information, not medical advice. Talk to your clinician before stopping any medication, and a nutrition coach about keeping your results.
