How does Mounjaro® work for weight loss?

Mounjaro contains tirzepatide, which is a dual GIP and GLP-1 receptor agonist. That means it mimics two natural hormones that help regulate blood sugar, appetite, and digestion. By slowing gastric emptying and increasing feelings of fullness, Mounjaro helps reduce food intake and support weight loss.
In clinical studies, people taking the highest dose of Mounjaro lost up to 20.9% of their body weight over 72 weeks.
You may be eligible for Mounjaro if your BMI is 30 or above, or 27+ with a weight-related health condition (such as high blood pressure or PCOS). You can speak to a Juniper prescriber by clicking the ‘Am I eligible?’ button to find the right treatment for you.
How soon will I see results with Mounjaro®?
On average, you can expect to lose between 5-10% at 3 months, 10-15% at 6 months and 15-20% at 12 months. It’s important to keep in mind that these weight loss rates have been carefully estimated based on published data that show weight loss outcomes at 72 weeks5
.Juniper members lose 40% more weight after 16 weeks than clinical trials of the medication show4. This means you’ll get better results sooner with Juniper’s support.
Is Mounjaro® safe?
When prescribed appropriately and monitored by a healthcare professional, Mounjaro (tirzepatide) is considered safe and effective for many people.Like all medicines, it can cause side effects, most commonly nausea, diarrhea, constipation, or decreased appetite — especially when you’re first starting or increasing the dose. These effects are usually mild and improve over time.
More serious risks are rare but can include pancreatitis or gallbladder issues. Your prescriber will review your medical history, current medications, and risk factors to make sure Mounjaro is a safe option for you.
Clinical trials (such as the SURMOUNT-1 study, published in the New England Journal of Medicine in 2022) have shown that tirzepatide is both effective and well-tolerated for most participants.
With Juniper, you’re not on your own — our care team provides regular check-ins, dose adjustments, and support for side effects to ensure you’re safe and comfortable throughout your treatment.
What are the side effects of Mounjaro?
Common side effects include nausea, diarrhoea, decreased appetite, vomiting, constipation, and indigestion. These often improve over time. Your Juniper membership includes unlimited access to a UK-registered prescriber who is on hand to monitor symptoms, side effects and weight plateaus, plus answer any questions you have about the medication.
More serious but rare side effects may include pancreatitis, gallbladder issues, or allergic reactions.
Always report any concerning symptoms to your GP.
How do I know if I’m eligible for Mounjaro?
You may be eligible for Mounjaro if you meet certain health criteria. In general, this includes:
A BMI of 30 or above, or
A BMI of 27 or above with a weight-related health condition (such as high blood pressure, sleep apnoea, or PCOS).
At Juniper, eligibility is assessed by a qualified prescriber, who will look at your full health history, current medications, and lifestyle factors before recommending treatment.
Even if you meet the BMI criteria, your prescriber will confirm whether Mounjaro is safe and suitable for you, and discuss alternatives if another option may be a better fit.
With Juniper, you’ll also receive ongoing monitoring and support, so your treatment can be adjusted to your needs over time.

How does Mounjaro® work?
Mounjaro quiets the ‘food noise’ and constant hunger pangs so you can make informed decisions about food.
By delaying gastric emptying and encouraging smaller portion sizes, you naturally eat less without feeling deprived.
By targeting two hormone pathways, the medication targets stored fat rather than muscle, helping you burn fat more efficiently.
With decreased cravings and increased feelings of fullness, it’s easier to build healthier habits to lose weight and keep it off in the long term.

Are weight loss injections safe?
When prescribed by a qualified healthcare professional and monitored carefully, weight loss injections like Mounjaro are generally considered safe and effective.
Like all medicines, they can cause side effects. The most common are nausea, diarrhoea, constipation, or reduced appetite, especially when starting or increasing the dose. These usually improve as your body adjusts. More serious side effects are rare, but your prescriber will check your medical history to make sure treatment is safe for you.
At Juniper, you’re never on your own. Our care team provides regular check-ins, ongoing monitoring, and support for managing side effects, so you can feel confident and supported throughout your treatment. A Juniper prescriber will take the time to understand your situation and recommend the safest and most effective option for you.
Do I have to take weight loss medication forever?
Not necessarily. The goal is to use medication as a tool to help kickstart weight loss while building sustainable habits. Some people continue long-term, while others may stop once they’ve achieved their goals and developed new routines. Your Juniper prescriber will work with you to plan what’s right for you.
Can I cancel with Juniper any time?
Yes. With Juniper, there’s no long-term lock-in. You can cancel your membership at any time if you feel the programme isn’t right for you.

Your health journey is personal, and we’ll always respect your choice.
Isn’t the medication enough, why do I need Juniper’s programme?
Medication helps regulate appetite and makes weight loss easier, but lasting success depends on long-term lifestyle changes. Without support, many people regain weight after stopping treatment. Juniper’s programme is designed to help you:
- Build sustainable eating and movement habits
- Understand your triggers and patterns
- Get expert guidance when challenges arise
This combination of medical treatment + behavioural support is proven to be the most effective path to long-term weight management.
