Ozempic has changed the way we treat diabetes. But it is its ability to aid rapid weight loss that has captured the world's attention.

Hack unpacks Ozempic with best-selling author Johann Hari, obesity expert Dr Kathryn Williams...and a couple of bodybuilders too.

Guests:

Johann Hari, author

Dr Kathryn Williams, obesity expert, University of Sydney
