Description: Episode 314
Weight-loss drugs Ozempic and Wegovy have been shown to slow down - or even reverse - the ageing process. In a trial of 84 people taking semaglutide, their biological age dropped by 3.1 years on average, with some organs becoming almost 5 years younger. Based on this new research, this finding could make these some of the most impactful anti-ageing drugs on the market. So how are they doing it?
