The use of weight loss injections in the UK is showing no signs of slowing down, but research into the short and long-term impact of taking these drugs is still emerging. While we know that GLP-1 medication (aka a weight loss jab) is effective at speeding up fat loss, new evidence is revealing the impact it can have on other parts of the body - namely, our muscles.
A new report by Les Mills, in collaboration with the ukactive Research Institute, found that when people use medications such as Ozempic, Wegovy and Mounjaro, 20 to 50% of the weight they lose is lean body mass – that's everything in your body apart from fat, including muscle.
