Our range of weight loss treatments are scientifically proven to help you lose weight, but what does that really mean? Let’s look at the main ways weight loss medications work alongside your body and not against it.
The active ingredients in some medications can suppress your appetite and the result is that you’ll start to feel less hungry. Those annoying food cravings? Gone!
By slowing down how long it can take food to pass through your system, the active ingredients in some medications can help you feel fuller for longer. You’ll feel more satisfied after eating.
When food passes through your digestive system, some medications act by reducing the amount of fat that is then absorbed into the body, by as much as 25-30%.
It’s important to remember that adopting a healthier diet & lifestyle will also play a key role in the success of your weight loss journey. Our expert team are with you at each step.
Clinical studies focusing on the active ingredients used in the Mounjaro (Tirzepatide) and Wegovy (Semaglutide) weight loss injections have shown consistent weight loss results of up to 22.5% and 15% respectively. These results were achieved when the medications were combined with adjustments in diet & lifestyle.
Weight loss medications are designed for the long-term, but you should notice changes throughout your journey and in the early stages.
The medication will start working inside your body once you take it, even if you don’t notice a difference straight away.
Notice changes in your weight and lifestyle as your body works with the medication.
You should be experiencing controlled weight loss and leading a healthier lifestyle.

They are science-backed weight loss options that have been designed to support long-term weight loss. They’re an alternative option for people who don’t want to self-inject.
