What a plateau looks like
On a chart, a plateau is a flat stretch in your trend line that lasts for weeks. It isn't one high weigh-in: single weights still go up and down inside it.
A 2025 joint advisory on nutrition with GLP-1 medicines, from four US medical and nutrition societies, describes weight loss on these medicines as generally faster at first, then slowing and leveling off.1 So a slower stretch can be part of the usual pattern. It isn't a verdict on you.
Why a weekly trend says more than one weigh-in
Weight moves from one day to the next. In a study of more than 1,400 adults in a European weight-maintenance trial, weight tended to rise a little at weekends and fall again during the week.2
One morning's number says little on its own. Weighing at a similar time of day helps, and the trend over a few weeks says more than yesterday's weigh-in.
Onederland's Progress chart draws a smooth trend through your weigh-ins, so a flat stretch shows as a flat line rather than a scatter of ups and downs.
Put your weight beside your dose steps
The Zepbound and Wegovy labels begin with a low dose and raise it in steps, so a chart often shows several dose changes.34 The Zepbound tracker page lists that label's steps.
With your trend and your doses on one timeline, it's easier to describe what happened: whether the flat stretch began on a steady dose, after a dose step, or around a missed or late dose.
A plateau isn't a reason to change your dose on your own. Your prescriber decides your dose. Talk to your prescriber before changing your dose.
What to note for your prescriber
A few notes make the conversation easier: when the flat stretch started, your dose and any dose changes, missed or late doses, and side effects that changed how much you ate.
It can help to note what else changed too: sleep, activity, stress, a new medicine, an illness or a change in routine.
Onederland can export a PDF report of your doses, weight, food, sleep and activity for the range you choose, to bring to an appointment.
Food, protein and activity
The joint advisory lists enough protein and strength training among its priorities for people on GLP-1 medicines, to help preserve muscle while weight comes down.1 Our guide to protein on a GLP-1 covers what it says.
A flat line is information
The scale is one way to see change. Notes on how you feel, your energy, how clothes fit and your side effects belong in the picture you share with your care team too.
