Stopping GLP-1 Medication: Rebuilding Your Relationship with Food

If you have been prescribed a GLP-1 medication and you and your prescriber are planning to stop it, one of the biggest changes can be your relationship with food. After months of a quiet appetite, hunger and food thoughts coming back can feel unsettling. This guide is about rebuilding trust in your hunger and fullness, eating in a way that feels like care rather than control, and looking after your body through the change. It is written for people already on treatment, working with their prescriber.

What changes when the medication stops

These medicines work by quietening appetite and slowing digestion. When they stop, those effects wear off, and hunger and fullness signals move back towards where they were.

The research is fairly consistent. On average, people regain much of the weight they lost after stopping, although individual experiences vary widely. A 2026 review of the research found that weight regain after stopping weight-management medicines is common, and faster than after behavioural programmes, and its authors called for a more comprehensive approach than medication alone.

Australian Prescriber puts it simply: when treatment is stopped, regaining weight is the norm. That is physiology, not a lack of willpower, and knowing it in advance takes some of the fear out of it. It also means the most useful thing to plan for is not a number, but how you want to eat and feel once your appetite returns.

Protecting muscle before and after

Muscle is lost along with fat during weight loss. Australian Prescriber notes a particular concern: weight that is regained may come back proportionally more as fat than as muscle. It recommends that people are supported to build and maintain muscle both while on treatment and once they have stopped.

The usual approach is enough protein spread across the day plus regular resistance activity, such as bodyweight exercises, bands or weights. The evidence that this fully protects muscle during GLP-1 treatment is still mixed, but it is low-risk and widely recommended, and it is much easier to start while you are still on the medication than afterwards.

Protein foods that tend to be easy to fit in include eggs, Greek yoghurt, milk, cheese, fish, chicken, lean meat, tofu, tempeh, lentils and beans. Resistance activity does not need a gym: a few sessions a week of squats, wall push-ups, step-ups or resistance bands all count, and a physiotherapist or exercise physiologist can help you start safely if you have joint or health concerns.

Rebuilding your relationship with food

For many people, the hardest part of stopping is the return of hunger and food thoughts after months of quiet. That is your body’s normal signalling coming back online, not something going wrong. A few principles help:

• Treat hunger as information, not a threat. Eat when you are hungry rather than waiting until you are ravenous, and notice when you have had enough.
• Keep a regular eating rhythm. Skipping meals and then getting very hungry makes it harder to eat in a way that feels good.
• Let all foods fit. Strict rules and banned foods tend to backfire, often setting up a cycle of restriction and overeating that is hard on both body and mind.
• Build meals you enjoy around protein, vegetables and higher-fibre foods, which tend to be satisfying, and leave room for the foods that matter to you socially and culturally.
• Keep up the activity habits you have built, particularly strength work, for how they make you feel rather than as a way to earn food.

If you notice yourself wanting to cut back hard, skip meals to compensate, or feeling anxious or out of control around food, please talk to someone about it. That is common after a big change in appetite, and it deserves support. Ausclin also offers eating disorder support, and we will talk it through gently and without judgement.

There is some early evidence that staying active helps. In one small trial, people who had supervised exercise alongside their medication were better able to maintain their health gains a year after stopping than those who had the medication alone. It was small, used an older medicine and tested exercise rather than diet, so treat it as encouraging rather than proof, but it fits the wider advice.

Dietitians Australia recommends that people prescribed these medicines are supported with nutrition and lifestyle counselling before, during and after stopping.

Working with your prescriber on the transition

Stopping is a decision to make with your prescriber, not alone. The reasons people stop vary, from side effects to cost to reaching a goal, and the right approach differs. There is no clear guidance yet on the best way to taper, so be wary of any plan that promises one.

It can also help to line up nutrition support for the weeks around stopping, so there is a plan in place when your appetite changes rather than afterwards.

Questions that are worth taking to that appointment:

• Why are we stopping now, and what are the options?
• Do any of my other medicines need reviewing when this one stops?
• What should I watch for in the first few months, and when should I come back?
• Would blood tests be useful before or after stopping?
