Join geneticist and neuroscientist Giles Yeo as he discusses how we use genetics as a tool to understand the biological variation in appetite control. Giles Yeo is a neuroscientist and geneticist at the University of Cambridge. He is a Principal Research Associate and group leader at the University Metabolic Research Labs, studying brain control of food intake and bodyweight.
