Ozempic and Wegovy - the brand names for semaglutide - were first created to treat diabetes, but have proved to be highly effective at combating obesity, with patients on the highest doses of the weekly injections shedding up to a fifth of their body weight.
Now medical firm Abbott has launched a line of high-protein, low-fat milkshakes in the US that are designed to maintain muscle mass among people taking weight-loss drugs, and which experts hope could soon be available in the UK.
According to Abbott, its Protality beverages, which cost about £3 each, will be crucial for semaglutide patients, while other firms have also launched other products to combat the loss of muscle.
Weight-loss drugs including Ozempic, while effective at combating obesity, also have muscle-wasting side effects
Last year Weight Watchers launched an app which provides nutrition tips to people taking semaglutide - the firm now also arranges access to private clinicians who can prescribe it. Some companies are even developing medicines to take alongside the injections which can counteract muscle loss.
