Mounjaro & Wegovy before and after: Our case studies

These stories come directly from our patients. Every journey is different, but each one shows what can happen when the right treatment is combined with the right support. We’re incredibly proud of what our patients have achieved. Here, we celebrate their progress and recognise their hard work as they inspire others with their journeys.

Our patients' Mounjaro results 

Liza has lost 4 stone and 3 pounds 

“I have gained so much confidence and a sense of control over my life again.” 

Why Liza started treatment 

Liza decided to start weight loss injections after struggling with her weight for years and finding that diets weren’t working for her anymore. 

“I decided to start weight loss injections because I’ve struggled on and off with my weight for years, trying every fad diet out there — and nothing worked.” 

Over time, her weight increased from 11 stone to 14.12 stone, partly due to mental health challenges and medication she had been prescribed for anxiety. After trying to lose weight between October and February without success, she decided to try Mounjaro. 

“That’s when I decided to apply for Mounjaro — it felt like the first option that might actually work for me.” 

Starting treatment 

Liza first started treatment in March through a private doctor, but later switched to myBMI after seeing other patients share their experiences online. 

“When I applied, the whole process was so easy and straightforward, and I was approved really quickly.” 

Liza’s results 

Since starting treatment, Liza has lost 4 stone 3.3 pounds in total over 27 weeks. 

Support during treatment 

During her journey she experienced some side effects, including constipation and stomach acid, but says the support she received made a big difference. 

“From myBMI, I’ve had amazing support with all of my side effects. Any time I’ve had a question, it’s been answered quickly and efficiently.” 

Lifestyle changes 

Alongside medication, Liza also made changes to her lifestyle, including staying in a calorie deficit, increasing protein intake, walking more, and introducing strength training. 

Confidence and wellbeing 

The biggest change for Liza has been how she feels physically and emotionally. 

“Physically I feel lighter. I can now walk up the stairs without killing myself.”

Lifestyle changes

Alongside treatment, Mick focused on improving his relationship with food and building healthier routines.

Confidence, energy and mental wellbeing

“My ability to manage stress in work and at home has been noteworthy. That's been huge.”

He says his confidence has increased significantly in everyday situations.

Life after losing weight

Mick says the transformation has had a noticeable impact on daily life with his family.

“Running around after young kids in your early 40s is so much easier.”

Mick’s advice for others

“Try surround yourself with facts. Do your research properly. Understand what the potential side effects are and just back yourself.”

Sonya has lost 38kg

“I am not hiding anymore.”

“Not being able to play with my kids and just feeling miserable all the time.”

Starting treatment with myBMI

Sonya first heard about myBMI through her sister, who was already using the service.

“My sister was using it and I told her I had talked to my doctor about going on a GLP-1 and she told me how good it was.”

“Surprised with how easy it was from start to finish. A couple of days from the initial consultation and I had it at my doorstep.”

Sonya’s results

Over 12 months, Sonya has lost 38.3kg.

Support during treatment

Sonya says the monthly consultations helped her stay informed throughout the process.

“With doing the consultations every month, it is handy to be able to ask questions about the stage you are at and what the next steps would be.”

Lifestyle changes

Alongside medication, Sonya noticed significant changes in her eating and exercise habits.

“My diet has become so much better. I do not obsess over the chocolate or crisp — I wouldn’t even think of them which is mad for me.”

“I have joined a sports club and a running club and my goal this year is to get to 10k.”

Confidence and wellbeing

Sonya says the biggest changes have been physical, emotional and social.

“Physically I can do so much more — running, walking — getting up off the floor after playing with my kids.”

“Socially, I am not hiding anymore.”

“I can think more clearly, sleeping better and getting out for fresh air has helped a lot with the mental side of things.”

Life after losing weight

One of the most surprising milestones for Sonya has been fitting into a size 10.

“Fitting into a size 10. I do not remember ever being a size 10.”

Friends, family and people around her have also noticed the transformation.

“Everyone who sees me are in shock. I have always been big as long as I can remember.”

Sonya’s advice for others

“Do not listen to what other peoples opinions are. It is your life — do it for YOU.”
