The ‘weight loss revolution’ changing the world

Available for over a year

During Sunday's Super Bowl in California, a flurry of ads from drug manufacturers and telehealth companies implored viewers at home to "ask their doctor” about a class of weight loss drugs, known as GLP-1s. These medications — like Mounjaro and Wegovy — have become ubiquitous. In just a few short years, they’ve transformed the way we live, move, and eat, whether we take them or not. And access and demand are only increasing, as pill forms of the drugs come onto the market. But where did they come from? And how are they reshaping our world? Today, we speak to Giles Yeo, a professor of molecular neuroendocrinology at the University of Cambridge, about the so-called weight loss revolution.
