Hollywood has gone into overdrive trying to guess which celebrities are using weight loss drugs. Elon Musk, Oprah Winfrey, Amy Schumer, and Rebel Wilson have all talked openly about taking them - and there have been loads of rumours swirling around Kim Kardashian.

These drugs are often known by their brand names Ozempic and Wegovy, made by the Danish company Novo Nordisk. Who are these drugs meant for and how effective are they? Kevyah Cardoso from the What in the World team explains. We also hear from someone who is taking these weight loss drugs.

麻豆社 health and science correspondent James Gallagher describes how these drugs, known as semaglutides, work. And TikTok doctor Dr. Austin does some myth busting for us, including if Ozempic babies are a thing.

A black market has grown up to supply people who want to use so-called 'skinny jabs' for cosmetic reasons. 麻豆社 journalist Pria Rai tells us about her investigation.
