Inside the venom of a desert lizard, scientists found a molecule that does something the diet industry spent 50 years failing to do. It quietly switches off hunger.
That molecule is now the most talked about drug on the planet, and it's sitting in the fridges of millions of people who couldn't explain how it works if you paid them.
Dr Tom Buckley, 30 years in medicine and a professor at Sydney University, has looked at the evidence and called these drugs revolutionary.
But what about "Ozempic face"? What if the wait comes back after you stop? Who should never touch these drugs? Dr Tom and Andrew get into the science so you finally have all the answers you need.
