Did you know that the secret behind modern weight-loss and diabetes drugs like Ozempic and Wegovy came from a venomous lizard? Scientists discovered that the Gila monster's saliva contains a peptide that acts as a super-stable version of our own hunger-regulating hormone, GLP-1. While we only make GLP-1 for about 90 seconds after eating, the lizard's version stays active for much longer, providing the perfect blueprint for the life-changing medicine.
