Mounjaro Muscle Loss: How to Avoid Ozempic Butt in 2026

Mounjaro has helped thousands of people across the UK lose significant amounts of weight, improve their health and regain confidence.

However, as more people use GLP-1 medications such as Mounjaro and Wegovy, a new term has emerged online: "Ozempic Butt".

While it may sound humorous, it highlights an important aspect of rapid weight loss that many patients overlook.

The good news is that muscle loss is not inevitable, and there are practical steps you can take to protect your muscle mass while achieving excellent weight loss results.

What Is Ozempic Butt?

"Ozempic Butt" is not a medical diagnosis.

The term refers to the appearance of flatter, less firm buttocks that some people notice after losing weight quickly.

This change occurs because weight loss can reduce:

1. Body fat.
2. Muscle mass.
3. Soft tissue volume.

As a result, some people notice changes in body shape, particularly around the buttocks, thighs and face.

Importantly, this is usually linked to rapid weight loss rather than being a direct side effect of Mounjaro itself.

Does Mounjaro Cause Muscle Loss?

Research suggests that some muscle loss can occur during weight loss, regardless of whether weight is lost through:

1. Dieting.
2. Exercise.
3. Weight loss surgery.
4. GLP-1 medications such as Mounjaro.

Studies suggest that up to one-third of total weight loss may come from lean mass rather than fat alone.

This is why preserving muscle while losing fat has become an increasingly important topic among obesity specialists.

Why Muscle Matters

Many people focus only on the number on the scales.

However, muscle plays a crucial role in overall health.

Maintaining muscle helps:

1. Improve metabolism.
2. Support mobility.
3. Maintain strength.
4. Improve balance.
5. Reduce injury risk.
6. Support healthy ageing.
7. Improve long-term weight maintenance.

Losing fat while preserving muscle is generally considered the ideal outcome.

New Research Offers Hope

Researchers are currently investigating a new medication called apitegromab.

The treatment works differently from Mounjaro and is designed to reduce muscle breakdown.

In an early clinical study involving adults taking Mounjaro:

1. Participants receiving apitegromab preserved more muscle mass.
2. They maintained approximately 55% more lean mass.
3. Fat loss continued alongside muscle preservation.
4. Weight loss remained effective.
5. Overall body composition improved.

Although the results are promising, the medication is still being studied and is not currently available for routine prescribing in the UK.

How to Protect Muscle While Taking Mounjaro

The good news is that there are proven ways to reduce the risk of muscle loss while using Mounjaro.

1. Increase Your Protein Intake

Protein provides the building blocks needed to maintain muscle.

Try to include protein with every meal.

Good options include:

1. Chicken.
2. Fish.
3. Eggs.
4. Greek yoghurt.
5. Lean beef.
6. Lentils.
7. Chickpeas.
8. Tofu.

Many experts recommend aiming for a protein source at every meal.

2. Prioritise Strength Training

You do not need an expensive gym membership.

Strength training can include:

1. Bodyweight squats.
2. Resistance bands.
3. Push-ups.
4. Step-ups.
5. Dumbbell exercises.
6. Yoga.
7. Heavy gardening.
8. Stair climbing.

Aim for at least two strength-focused sessions per week.

3. Avoid Crash Dieting

Mounjaro naturally reduces appetite.

Some patients accidentally eat far too little.

Extremely low calorie intake may increase the risk of muscle loss.

Instead, focus on:

1. Balanced meals.
2. Adequate protein.
3. Regular hydration.
4. Sustainable eating habits.

4. Stay Active

Regular movement helps preserve muscle and improve overall health.

Examples include:

1. Walking.
2. Cycling.
3. Swimming.
4. Hill walking.
5. Resistance training.

Consistency is more important than intensity.

Why Mounjaro Is Still One of the Best Weight Loss Treatments Available

The possibility of muscle loss should not discourage suitable patients from seeking treatment.

Mounjaro remains one of the most effective weight loss medications currently available.

Patients often experience:

1. Reduced appetite.
2. Less food noise.
3. Improved portion control.
4. Significant weight loss.
5. Better blood sugar control.
6. Increased confidence.
7. Improved quality of life.

The key is to combine treatment with healthy lifestyle habits that support long-term success.
