Keeping it off
Your weight after stopping a GLP-1: fluctuations, trends and a steady zone
The short version
- Day-to-day weight changes by a kilo or more with water, salt, sleep and hormones.
- A 7-day average shows the real trend.
- A small steady zone above your lowest weight tells you when, and only when, to act.
- Weighing is optional. If it doesn't help you, other signals work too.
Why the scales jump around
A salty meal, a drink, a short night, a hard workout or your menstrual cycle can move the scales by a kilo or more overnight. None of that is fat. When appetite returns after stopping a GLP-1, you may also carry a little more food and water day to day. Reacting to every number is exhausting and tells you very little.
Use a 7-day average
If you weigh yourself, do it at the same time a few mornings a week and look at the average across seven days. The average smooths out the noise and shows which way things are really heading.
Set a steady zone
Pick a small range, for example up to 2% above your lowest weight. While your 7-day average sits inside it, you're holding steady, whatever single days say. If the average sits above it for a couple of weeks, that's your cue to go back to basics for a week, not to panic. See how to keep weight off.
If you'd rather not weigh yourself
You don't have to. How your clothes fit, how hungry you feel, your energy and whether your routines are holding are all useful signals. Steadie's safe mode hides weight completely and builds your weekly score from habits and check-ins instead.

Common questions
Is it normal to gain weight after stopping Mounjaro?
Yes, some regain is common as appetite returns. Look at the trend over weeks, not single days, and lean on protein, strength exercise and regular meals.
How often should I weigh myself after stopping?
If it helps you, a few mornings a week at the same time, looking at the 7-day average. If it doesn't help, you can skip it.
