How to Maintain Your Mounjaro Weight Loss

Reaching your goal weight with the help of Mounjaro is a huge achievement that takes dedication and consistency.

But if you’ve used Mounjaro (tirzepatide) to help you lose weight, you may be wondering: “What now?”

To help you maintain after reaching a healthy weight, we explain how you can keep the weight off – whether you’re continuing treatment or transitioning off the medication.

What Happens When You Reach Your Goal Weight on Mounjaro?

When you reach your goal weight on Mounjaro, you can either:

• continue Mounjaro for weight maintenance, or
• maintain your weight without it.

Each option comes with its own set of benefits and considerations. And the right choice will vary from person to person.

Stay on Mounjaro to Maintain Weight

To maintain your weight, you can continue taking Mounjaro at a maintenance dose.

“Obesity is now being seen as a chronic health condition,” explains Abdal Alvi, Simple Online Pharmacy’s Clinical Director. “Medications like Mounjaro can be used in the long-term and there’s not actually a limit for how long you can use them for.”

Mounjaro, which uses the active ingredient tirzepatide, works by slowing down the rate of digestion. This helps you feel fuller for longer. Staying on Mounjaro will continue to support appetite regulation. This makes it easier to sustain the progress you’ve worked hard to achieve.

However, staying on Mounjaro long-term may come with continuing financial costs by repurchasing the medication regularly.

Also, taking Mounjaro for a long period of time may increase the risk of potential side effects. This means your healthcare provider will need to continue monitoring you.

Stop Taking Mounjaro

This may appeal to you if you’d prefer to manage your weight with lifestyle changes alone.

If you decide to stop Mounjaro, your doctor probably won’t stop prescribing it immediately. Instead, they’ll gradually decrease your dose over several weeks. This can help your body adjust to changes – both physically and mentally.

During this time, it is important to reinforce new lifestyle habits, like healthy meal planning and regular physical activity. This can help provide a strong foundation for long-term success without medication. You should monitor any changes in appetite or weight and share them with your clinician.

Will I Gain Weight When I Stop Taking Mounjaro?

You might be concerned about gaining weight after stopping Mounjaro. While this may happen for some patients, not every patient will regain weight.

Clinical studies suggest that stopping GLP-1 receptor agonists, like Mounjaro, can lead to an increase in appetite and gradual weight gain. One trial found that individuals who stopped Mounjaro regained a significant portion of the weight they had lost within a year. 

However, this does not mean that weight regain is inevitable. Many patients who transition off Mounjaro successfully maintain their weight with sustainable lifestyle changes. This includes a healthy diet rich in whole foods, physical activity and techniques to support yourself emotionally.

If you’re considering stopping Mounjaro, it’s essential to work closely with your healthcare provider to monitor your progress. Together, you’ll develop a long-term strategy for maintenance after Mounjaro.

And remember that regaining some weight is not a sign of failure.

How to Maintain Weight Loss After Mounjaro

How do you keep the weight off after stopping Mounjaro? By continuing the healthy lifestyle, eating and exercise habits you built during your weight loss journey.

It has been shown that if you stop Mounjaro, it is likely that you will gain at least some of the weight that you have lost back. However, patients who make healthy lifestyle changes have more success with long-term weight loss.

“The medication by itself can be very successful,” Abdal says. “But it should really be used alongside some key lifestyle changes. Such as introducing a balanced, nutrient-dense diet and increasing the amount of exercise and movement.”

“So if [patients] were to stop the medication, they will have established a long-term habit that’s going to allow them to keep that weight off.”

Healthy, Mindful Eating

It’s important to stick with a well-balanced, nutritious diet. During your weight loss journey, your provider will encourage you to eat a diet made up of whole foods. This means eating plenty of fruit and veggies, lean protein and healthy fats.

One particularly helpful method for implementing a balanced diet long-term, is mindful eating.

Mindful eating allows you to focus on being mentally aware and present while eating. By engaging your senses and listening to your body, you are more likely to slow down while eating. This makes you less likely to overeat, helping you maintain your weight loss results in the long run.

Physical Activity

Increasing your physical activity levels is also recommended alongside Mounjaro.

The NHS recommends adults do 150 minutes of moderate exercise per week, or 75 minutes of vigorous exercise.

Continuing regular exercise is a key part of a healthy lifestyle. Not only is it important for overall health, it will help prevent weight gain.
