How to Keep the Weight Off When You Stop Taking Ozempic, Mounjaro or Other GLP-1 Medications
GLP-1 and related medications such as Ozempic (semaglutide) and Mounjaro (tirzepatide) have changed the landscape of weight management.
For many people, these medications can make weight loss achievable in a way that it hasn't been before, despite attempts at diet, exercise or lifestyle changes. They can significantly reduce appetite, increase feelings of fullness and change the constant drive to think about or seek out food.
But, we are noticing there are more and more people who are either considering this approach, or already taking GLP-1 medications, asking:
What happens when you stop taking them?
Research tells us that weight regain after stopping GLP-1 and related medications is common. That doesn't mean taking them was a mistake, or that regaining weight is inevitable.
It does mean that building the nutritional and dietary habits and behavioural foundations of a healthy lifestyle is key. While taking these medications, and seeing the benefits of reduced appetite and lessened cravings for certain foods, this is the perfect opportunity to make changes to your diet and lifestyle, so that when the medication is reduced or stopped, the healthy habits remain.
Why does weight return after stopping GLP-1 medications?
GLP-1 medications don't simply rely on willpower to help people eat less. They influence biological systems involved in appetite, satiety and digestion.
When the medication is withdrawn, those effects diminish. Hunger increases, fullness may not last as long, and some people notice the return of the "food noise" that had previously become much quieter.
Clinical research reflects this.
In the STEP 1 extension study, participants who stopped semaglutide regained approximately two-thirds of their previous weight loss over the following year. A withdrawal trial of tirzepatide similarly found substantial weight regain among people switched from tirzepatide to placebo. These findings demonstrate how strongly our biology can influence weight regulation and why long-term support matters.
Importantly, these studies do not mean everyone will regain all the weight they lose. They highlight the need to think beyond the number on the scales and consider what will support your health and weight over the longer term.
Don't wait until you stop the medication to think about maintenance
Ideally, preparation for life after GLP-1 medication begins while you are taking it.
When appetite is significantly reduced, it can be tempting to simply enjoy not being hungry and eat very little.
But eating less isn't necessarily the same thing as eating well.
A smaller volume of food means there are fewer opportunities to obtain adequate protein, essential fatty acids, vitamins, minerals and fibre. If food quality isn't prioritised, nutritional intake can become inadequate even while weight is dropping.
This is why the goal during GLP-1 treatment shouldn't simply be calorie deficits from asking “how little can I eat?”
A better question is: How can I use this period while on GLP-1 medications to establish a healthy way of eating and living that supports my long term health? Because for many people, they will achieve their weight loss goal and no longer need to take these medications. And there are some less than desirable effects of these medications to, so for many, the idea of staying on them long term is not appealing, despite the weight loss.
Protect muscle while you lose weight
One particularly important consideration during significant or rapid weight loss is maintaining lean muscle mass. Muscle mass is not just for appearance, it is connected to a range of health and longevity markers.
Adequate protein intake and resistance training exercises are important components of a healthy weight-loss program. Muscle isn't simply about strength or appearance. Maintaining muscle supports physical function, metabolic health and healthy ageing.
When your appetite is very low, however, getting enough protein can become incredibly difficult.
A naturopath or appropriately qualified health practitioner can assess what you are actually eating and help you develop realistic ways of obtaining adequate protein and nutrients within a smaller overall volume of food.
Look after your digestive system
GLP-1 medications affect the gastrointestinal tract and can slow down your digestive system. Nausea, vomiting, diarrhoea, abdominal discomfort and constipation are among the recognised side effects.
For some people, eating considerably less can also mean consuming less fibre and fluid, which may compound problems with the regularity of bowel movements.
Rather than accepting ongoing digestive symptoms as simply part of losing weight, it can be helpful to assess your overall diet, hydration, fibre intake and gastrointestinal health.
Individualised naturopathic support may include looking at food quality and fibre intake, bowel habits, gut health and the nutritional adequacy of your diet, while persistent or significant gastrointestinal symptoms should be discussed with the medical practitioner prescribing your medication.
Build an eating pattern before hunger returns
One of the benefits people commonly describe on GLP-1 medications is less ‘food noise”. Its as if the volume is turned down on any thoughts related to hunger, or any preoccupation with food.
Again, this can provide an opportunity to establish a different relationship with food.
Rather than waiting until appetite increases again, you can practise:
eating regular, nutritionally balanced meals
prioritising protein, vegetables, fibre and whole foods
recognising physical hunger and fullness cues
preparing simple healthy meals that are easy to maintain
finding foods you genuinely enjoy that also support your health
reducing reliance on highly processed convenience foods
establishing portions and routines that will be sustainable long term.
The goal isn't to have an increasingly restrictive diet. It is to create a way of eating you can realistically continue.
Exercise needs to become part of the picture too
If weight loss is occurring primarily because the medication has reduced how much you eat, it is possible to reach your goal weight without substantially changing your physical activity.
But that can leave an important part of long-term weight management unaddressed.
Walking, cardiovascular activity, mobility and particularly resistance or strength training can help support cardiovascular health, metabolic health, muscle mass, strength, mood and long-term physical function.
Again, it is much easier to establish these habits before stopping the medication than to suddenly overhaul your lifestyle once hunger has already returned.
What if emotional or habitual eating was part of the problem?
Not all eating is driven by physiological hunger cues.
Most of us will also eat - or overeat - when we are stressed, tired, bored, lonely, celebrating, socialising or out of habit because eating at a particular time or in a particular situation has become automatic.
GLP-1 medications can reduce appetite considerably, but they don't necessarily resolve all of the subconscious associations and behaviours around food.
This is where approaches such as hypnotherapy may complement nutritional and naturopathic support. Hypnotherapy can be highly effective for exploring and changing habitual and often subconscious patterns and associations around food, while helping establish new behaviours around eating, movement and self-care.
Rather than relying solely on motivation or willpower, the aim is to make healthier behaviours increasingly familiar and automatic.
Consider your metabolic health, not just your weight
Weight is only one marker of health.
Before, during and after GLP-1 treatment, it can be useful to consider factors such as blood glucose regulation, insulin resistance, cholesterol and triglycerides, blood pressure, nutritional status, digestive health and body composition.
Depending on your individual circumstances, pathology testing can help identify areas requiring attention.
At PNMC, our Naturopaths and holistic and integrative Nurse Practitioner can help look at the broader picture and consider what your body needs during weight loss and beyond.
A more sustainable approach to life after GLP-1 medications
There is no single strategy that guarantees someone will maintain all of their weight loss after stopping a GLP-1 medication.
For some people, ongoing medical treatment may be appropriate. Decisions about reducing or discontinuing prescribed medication should always be made with the prescribing medical practitioner.
But if you are considering coming off medication, it makes sense to prepare your body and your lifestyle for what comes next.
That might mean addressing nutritional deficiencies, protecting muscle mass, supporting digestive and metabolic health, learning how to build balanced meals, developing a sustainable exercise routine, and working on the emotional and subconscious patterns that influence eating.
The medication may have helped create the conditions for weight loss.
The next step is creating the conditions that help you maintain your health.
At Perth Natural Medical Clinic, our naturopaths, holistic and integrative Nurse Practitioner and hypnotherapist can work alongside your existing medical care to help you build a personalised approach to nutrition, metabolic health and sustainable lifestyle change.
