Weight Loss Transformation
Mounjaro has completely changed my relationship with food. The constant cravings and food noise have disappeared, and I finally feel in control and more confident than ever.
Understanding How Mounjaro Helps You Lose Weight
Mounjaro works by mimicking GLP-1, a natural hormone made in your gut that helps control appetite and digestion.
By acting like GLP-1, this treatment can support significant weight loss through two key effects:
- Reduces appetite: Helps regulate hunger signals, making it easier to eat less.
- Slows digestion: Helps you feel fuller for longer after meals.
Together, these effects naturally lead to eating fewer calories, which results in weight loss.
Following a reduced-calorie diet alongside treatment can enhance your results even further.
How Effective is Mounjaro?
When using Mounjaro KwikPens to reduce appetite, patients typically lose between 16% and 22.5% of their starting body weight by the end of treatment. This makes Mounjaro the most effective GLP-1 medication currently available.
These results are seen in patients who remain on the highest therapeutic dose of 15mg.
- Patients who stabilise at 10mg lose an average of 21% of their body weight.
- Patients who reach and maintain 15mg can lose around 22.5%.

Our clinical team is UK-based and fully registered with the General Pharmaceutical Council. Ask our Pharmacist?:
How can I manage side effects?
Most side effects, like nausea or bloating, improve with simple changes. Try to avoid fatty, oily or processed foods, and drink plenty of water throughout the day. Many gastrointestinal side effects are linked to diet, so eating lighter, balanced meals can make a big difference. If symptoms persist, our pharmacy team can offer further advice.
Can I transfer from another pharmacy?
Yes, absolutely. If you’re already using Mounjaro and want to continue with us, we can make the process simple. Just complete a short consultation and let us know you’re transferring and we’ll handle the rest.
Which exercise is best for weight loss whilst taking Mounjaro?
The best exercise is the one you enjoy and can stick to. A mix of walking, resistance training, and light cardio often works well. Even small changes, like taking the stairs or increasing your step count, can make a big difference when combined with Mounjaro.
