One of the questions I am being asked more and more is very simple: “Can I come off Mounjaro without putting all the weight back on?”
The answer is that weight regain after stopping Mounjaro is common, but putting every pound back on is not inevitable. What matters enormously is what happens around that transition. In my work with clients, I don’t see coming off Mounjaro as something that begins with the final injection. I believe the preparation needs to start while somebody is still taking it.
What happens when you stop Mounjaro?
Mounjaro is the brand name for tirzepatide, a medication that acts on GIP and GLP-1 receptors. Among its effects, it regulates appetite and increases feelings of fullness, which can make eating considerably less feel remarkably easy compared with previous attempts to change weight. NICE describes reduced hunger and fewer food cravings as important effects of tirzepatide.
And then comes the question I hear repeatedly: what happens when that support is no longer there?
The research gives us good reason to take the transition seriously. In the SURMOUNT-4 trial, people initially received tirzepatide for 36 weeks. Those subsequently switched to placebo regained a substantial proportion of the weight they had lost over the following year, whereas those who continued tirzepatide maintained and added to their initial weight reduction.
A more recent analysis of that study, published in JAMA Internal Medicine, looked more closely at what happened to 308 participants after tirzepatide was withdrawn. After one year, 82.5% had regained at least a quarter of the weight they had initially lost. Approximately half had regained at least half of their initial weight loss, while 17.5% regained less than a quarter. A small proportion continued to lose weight.
Those figures matter, but so does the way we interpret them. They do not show that everybody who stops Mounjaro puts all their weight back on. They show that regain is common, that the amount varies considerably between people, and that the period after treatment deserves far more attention than simply reaching a target weight.

Does food noise come back after Mounjaro?
For many people, one of the most extraordinary effects of Mounjaro has nothing to do with the number on the scales. It is the sudden quietening of what has become known as “food noise” — persistent thoughts about food, eating, what to eat next or the effort involved in resisting it.
When appetite begins to increase again, some people find those thoughts become more noticeable too. This can be particularly difficult if somebody has interpreted the absence of food noise as evidence that their previous relationship with food has somehow permanently disappeared. Current British Dietetic Association guidance for people taking weight-management medication specifically includes food noise and longer-term changes to help prevent weight regain after stopping treatment.
This is where I think we need to distinguish between appetite and eating behaviour.
Mounjaro can have a powerful effect on appetite and food intake. But if somebody previously ate because they were stressed, lonely, angry, bored, exhausted or simply because food had become their habitual way of changing how they felt, losing their appetite does not necessarily resolve the reason that behaviour developed in the first place.
That is why I work on emotional eating while somebody is still taking Mounjaro, rather than waiting to discover what happens afterwards.

The transition should start before you stop
This is the central principle behind my Mounjaro Transition™ work.
If somebody has spent months eating considerably less because their appetite has been suppressed, I don’t want the first serious conversation about how they are going to live without that support to take place after their final injection.
While the medication is still helping, we have an extraordinary opportunity to establish what needs to remain afterwards. That includes eating structure, the quality of the food somebody is eating, emotional eating, alcohol, movement, skeletal muscle, sleep and stress.
It is interesting that the official guidance is increasingly recognising the importance of what happens afterwards too. NICE now specifically recommends advice and continuing support for people stopping weight-management medication, because maintaining behavioural changes can help prevent weight regain and weight cycling.
Protecting muscle matters too
The conversation around Mounjaro has understandably concentrated on kilograms lost, but body composition matters enormously.
When somebody is eating considerably less, simply making the number on the scales smaller is not enough. I want to know what is happening to their skeletal muscle as well as their body fat.
Current British guidance for people using weight-management medication specifically addresses adequate protein, preserving muscle mass and movement alongside longer-term maintenance.
This becomes particularly important when somebody is thinking about maintaining their results. Muscle is metabolically active tissue. Maintaining it also matters for strength, function and how the body looks and feels — particularly from midlife onwards.
I explain this in more detail in How to Avoid Muscle Loss on Mounjaro, Ozempic or Wegovy.
What should you eat when coming off Mounjaro?
I want somebody to understand how to eat.
For me that means establishing a sensible structure to the day; eating proper food; including adequate protein; eating plenty of vegetables, salad, fruit, pulses, seeds and other fibrous carbohydrates; understanding where starchy carbohydrates fit; and looking realistically at alcohol and the foods that somebody tends to eat when they are not physically hungry.
It also means eating enough of the right foods. The objective isn’t to recreate the dramatically reduced appetite somebody may have experienced on Mounjaro through sheer willpower. It is to establish a way of eating that can actually belong to them.

Emotional eating doesn’t disappear because appetite does
This is the part of the conversation I think is too often missed.
Somebody can lose a considerable amount of weight without ever addressing why they ate when they weren’t hungry. If Mounjaro makes that behaviour temporarily much easier to resist, that can be enormously helpful. But it also gives us a window in which to understand it.
In my work as an eating psychology coach, I look at the circumstances surrounding non-hunger eating. When does it happen? What feeling tends to precede it? What has food historically provided at that moment? What other patterns have become attached to particular times, places, people or emotions?
The objective isn’t simply to produce somebody who is better at saying no to food. It is to reduce the need to use food for a job it was never really designed to do.
I explore some of the origins of these patterns in Why Do I Eat When I’m Not Hungry? The Answer May Have Started in Childhood.
How I work with clients through their Mounjaro transition
There isn’t one transition that is right for everybody, which is why I work with each client individually.
As their medication changes, we look carefully at what is happening to appetite, food noise, hunger, eating behaviour and body composition. We can then work on the nutrition and behaviours alongside that changing level of support, rather than somebody reaching their final injection and suddenly finding themselves on their own.
The transition is therefore not simply about reducing a dose. It is about balancing the change in medication with the changes we are making to somebody’s everyday life. What happens to their hunger? Is food noise beginning to return? Are old emotional-eating patterns becoming more noticeable? Are they eating sufficiently well? What is happening to their skeletal muscle? How are they coping with weekends, restaurants, alcohol, holidays and stressful periods?
Dose changes themselves need to remain consistent with the medical instructions supplied with Mounjaro and any relevant clinical advice; the UK patient information leaflet states that patients should not change their dose unless instructed by their doctor. My work is the practical transition around that process: helping somebody establish the eating, behavioural and body-composition changes that need to work alongside it and, crucially, afterwards.
Can you keep the weight off after Mounjaro?
There is no responsible way to promise somebody that they will never regain weight after stopping Mounjaro. The research simply doesn’t support such a guarantee.
But the research doesn’t tell us that everybody inevitably puts all their weight back on either. The 2026 analysis showed considerable variation between individuals after tirzepatide withdrawal: 82.5% regained at least a quarter of their previous loss, but 17.5% regained less than a quarter, and a small proportion continued losing weight.
My interest is in what we can actually influence.
What are you eating? Have you protected your skeletal muscle? What happens when you’re stressed? What happens when you’re tired? Has alcohol quietly crept back in? Do you understand your emotional eating? What does your normal week look like? Have you built habits that work in restaurants, on holiday, at weekends and when life becomes difficult?
Those are not questions to begin asking six months after Mounjaro. They are the work to do while it is still helping you.
Mounjaro should be part of the story, not the whole story
For some people, Mounjaro has been transformative. I don’t diminish that for a second. But I don’t want somebody’s confidence in maintaining their body to exist entirely inside an injection pen.
The medication can create an extraordinarily useful period in which appetite is quieter and change may feel easier. I want to use that period intelligently.
That means working on nutrition, eating psychology, body composition, skeletal muscle and the practical realities of somebody’s life before the pharmacological support changes.
Because ultimately, when somebody reaches the point where they are ready to come off Mounjaro, I want them to arrive there with considerably more than a lower number on the scales. I want them to understand their body, their eating and the behaviours that need to support them afterwards, so that they have a proper plan for what comes next.
If you are taking Mounjaro, Ozempic or Wegovy and would like individual support preparing for long-term maintenance, my Mounjaro Transition™ Programme is designed specifically for this stage.
