Can Mounjaro help you to lose weight quicker?

We know how demotivating it can be when you’re trying to lose weight and progress seems slow. While it’s tempting to want to lose weight quickly, it’s rarely easy to maintain rapid weight loss. Instead, it’s crucial you focus on your longer-term goals. With Mounjaro Kwikpen, you may experience noticeable weight loss within the first few weeks from taking medication along, but diet and exercise play a big role too. Adopting a healthy lifestyle is essential to optimise your results and help you maintain your new weight.

Studies show you’re more likely to keep excess weight off for good if you lose a little consistently over time, rather than crash dieting for rapid and dramatic weight loss. Mounjaro can be a great tool for supporting long-term, maintainable weight loss results. The 72-week SURMOUNT-1 study found adults on a 5mg dose lost on average 16% of bodyweight while those on 15mg lost 22.5%.

How does Mounjaro speed up weight loss?

Mounjaro works by activating receptors in your body and brain that tell you that it’s time to stop eating. It does this by stimulating insulin release and helping control blood sugar levels. These two things can make you feel less hungry and curb food cravings, so you eat smaller portions and feel fuller. It can also help speed up your metabolism and help your body burn fat faster. Because you eat less, Mounjaro and other weight loss injections can support healthy weight loss and make it easier to stick to a calorie-controlled diet.

Diet and exercise still play a part

While Mounjaro will help speed up your weight loss it’s not a magic fix and you’ll need to follow a healthy lifestyle to improve your overall wellbeing and maintain your results. A balanced diet will provide essential nutrients for your body and help you avoid empty calories which could slow your progress.

When you lose weight, you naturally lose muscle as well as fat but exercising, particularly weight-bearing activities, can help conserve muscle mass. Regular exercise will also boost your energy levels and support your overall health – read our weight loss guides to help you stay on track.

Remember to drink plenty of water too. Mounjaro slows down your digestion and if you’re dehydrated it can increase some of the side effects, like nausea and constipation.

While alcohol’s not completely off the table, it can affect how much weight you lose. Some studies suggest it can also reduce alcohol cravings so you may not want to drink at all.

What do studies say about Mounjaro and Weight Loss?

Studies have shown people taking Mounjaro can expect to lose a significant amount of weight. How much exactly will depend on your personal circumstances including how overweight you are to begin with, any health conditions, sticking to a calorie-controlled diet, exercise, dosage and length of time you use weight loss injections.

During the SURMOUNT-1 study, overweight or obese adults with at least one weight-related complication (not diabetes) lost on average 16% on a 5mg dose, 21.4% on a 10mg dose and 22.5% on a 15mg dose over 72 weeks. Depending on dosage at least 89.4% lost 5% of their bodyweight compared to 27.9% on the placebo.

The SURMOUNT-2 study for overweight or obese people with diabetes produced similar results with 13.4% average weight loss on a 10mg dose and 15.7% on 15mg compared to a 3.3% loss on the placebo.

It is essential that you speak to a licensed medical professional before starting any weight loss medication. They can provide personalised, expert guidance, assess potential risks and ensure that your chosen treatment is safe and suitable for your health needs.

So, to answer your question...

Lots of people notice changes within a few weeks when they start losing weight with Mounjaro, especially when combined with a healthy diet and active lifestyle. Weight loss injections can lead to significant, steady weight reduction over time but it’s important to focus on consistency rather than rapid results. Mounjaro works best when paired with a sensible eating plan and regular exercise. While not an overnight solution, it offers a sustainable way to lose weight and keep it off for good.
