About the Guest: Professor Giles Yeo is a leading geneticist and obesity researcher, dedicated to bridging the gap between cutting-edge science and public understanding of why we eat the way we eat. Graduating from the University of California, Berkeley, before completing his PhD at Cambridge, where he has spent his career, Giles is one of the world's most credible voices in the biology of weight and appetite.

In his research at the MRC Metabolic Diseases Unit, he takes a rigorous, evidence-based approach to understanding how the brain controls food intake, body weight, and the genetic factors that drive obesity. Beyond the laboratory, he is a driving force in science communication, serving as a presenter for the BBC across flagship programmes including Horizon and Trust Me I'm a Doctor, helping bring complex nutritional science to millions worldwide. His commitment to cutting through diet misinformation is furthered by his bestselling books, including Gene Eating, which challenges the myths surrounding food, genetics, and personal responsibility.
