Giles Yeo got his PhD from the University of Cambridge in 1998, after which he joined the lab of Prof Sir Stephen O’Rahilly, working on the genetics of severe human obesity. Giles Yeo is now a programme leader at the MRC Metabolic Diseases Unit in Cambridge and his research currently focuses on the influence of genes on feeding behaviour & body-weight. In addition, he is a graduate tutor and fellow of Wolfson College, and Honorary President of the British Dietetic Association. Giles is also a broadcaster and author, presenting science documentaries for the BBC’s ‘Horizon’ & ‘Trust Me I’m A Doctor’. His first book ‘Gene Eating’ was published in December 2018, and his second book ‘Why Calories Don’t Count’ comes out in June 2021. Giles was appointed a Member of the Order of the British Empire (MBE) in the Queen’s 2020 birthday honours for services to ‘Research, Communication and Engagement’.


My group’s aim is to understand the molecular mechanisms underlying the central control of food intake and body-weight.
