Losing weight with Mounjaro is a real achievement, but keeping it off is often where the real challenge begins. While Mounjaro can help you lose weight more easily, long-term success is about maintaining healthy habits long after you’ve stopped taking the medication.

However, some people find this hard without the help of Mounjaro, and many find themselves slipping back into old habits. The good news is that, while weight regain is common, it isn’t inevitable. With the right strategies, you can give yourself the best chance of staying on track.

Key takeaways

  • The average patient regains up to 0.4 kg every month after stopping weight loss treatment.
  • Weight gain after stopping Mounjaro is completely normal, but it’s also preventable with healthy lifestyle choices.
  • Nutrition, physical activity, and stress management are essential to long-term success on your weight loss journey.
  • Minor weight fluctuations and plateaus are entirely normal. Success is defined by your long-term habits and cultivating a healthy, sustainable relationship with food.
  • To keep weight off successfully, consider using a maintenance dose of Mounjaro for long-term support.

Why weight gain after stopping Mounjaro is common

Maintaining weight loss after stopping Mounjaro can be difficult, and many of my patients find it challenging to stick to their new routines without support.

In fact, a study on weight regain after stopping weight loss treatment found that the average patient gained 0.4 kg of weight every month. That would mean if you lost 10 kg on Mounjaro, you would regain half of what you lost after a year. That’s a significant change in the long term, and it can be demotivating after months of progress.

Those switched to placebo experienced a 14% weight regain and those continuing tirzepatide experienced an additional 5.5% weight reduction during the 52-week double-blind period.

Can you maintain your weight after stopping Mounjaro?

While many struggle with weight gain after stopping treatment, it’s entirely possible to maintain your progress.

By focusing on sustainable lifestyle adjustments, you can bridge the gap between medication support and independent weight management that you can maintain in the long term. In this article, I explore the practical steps you can take to make this transition smoother.

People who develop and maintain long-term habits while they’re using Mounjaro are far more likely to keep the weight off after stopping treatment.

To give yourself the best chance of success, consider the following doctor-approved tips.

1. Prioritise lean protein

Research shows that protein can help with weight loss (and weight management) in a few key ways:

  • Keeps you satisfied: high-protein meals increase levels of hormones that signal fullness (e.g. GLP-1). This can keep you fuller for longer and prevent you from overeating.
  • Reduces hunger: protein also reduces levels of the hunger hormone (ghrelin), potentially curbing cravings.
  • Increases metabolism: around 20–30% of the energy found in protein is used to process and digest it, meaning less of it is stored as fat.

Making sure your diet contains plenty of high-protein foods can make it easier to stay within a healthy calorie range. For more nutrition advice, you can read our article on Foods to avoid during weight loss treatment.

2. Stay physically active

Physical activity is important when it comes to losing weight, but it’s equally important for keeping it off.

Whether you lift weights, run, swim, or walk, keep up with a consistent routine to help maintain your new weight after stopping Mounjaro.

3. Monitor your weight

It can be easy to lose focus after losing weight with Mounjaro, but small weight increases can add up to noticeable fat gain over time.

By occasionally monitoring your weight, you can spot any changes before they become significant. But remember, it’s important not to obsess over this. The scale doesn’t tell the full story, and there are other factors to consider.

4. Control your portions

Exercise is important, but the most significant factor for weight management is your diet.

Managing your portion sizes makes it easier to keep within a healthy daily calorie intake and can prevent unwanted weight gain. Read my article on How many calories you need to lose weight for more information.

5. Manage sleep and stress

High levels of stress and poor sleep can impact hormones that regulate appetite and metabolism, making it harder to manage your weight.

  • Stress: stress can increase cortisol, the stress hormone. This can cause you to store more fat on your body. To avoid this, try stress-relieving activities like mindfulness, yoga, or simply doing something you enjoy.
  • Poor sleep: not getting enough sleep can disrupt hormones that keep hunger in check. Try to get at least 7-9 hours of sleep every night to help manage your weight.

6. Set realistic expectations

Weight loss is rarely a straight line. Keep in mind that plateaus or small weight fluctuations are entirely normal.

Setting sustainable, long-term goals will help you build habits that last, making it easier to maintain your weight going forward.

What should I do if I start regaining weight?

Some weight gain after stopping treatment is entirely normal. However, continued weight gain can risk undoing the progress you made while taking Mounjaro.

To avoid this, make sure to stick to the healthy habits you developed during treatment. If you’re still having trouble, we’re here to help. Our doctors can help determine the best course of action.

Mounjaro maintenance dose

A maintenance dose of Mounjaro is the lowest dose that effectively helps you maintain your weight loss results in the long term.

For some people, this could be the lowest dose, while others may be better suited for the 15 mg dose. No matter the dose, Mounjaro can be part of a healthy long-term weight management plan for many people.
