The science of weight loss – and why calories don’t count! | Prof. Giles Yeo

Think weight loss is all about eating less and moving more? Think again. In this episode, Prof. Giles Yeo reveals why calorie counting isn’t just inaccurate—it could actually make weight management harder. He explains why the popular “calories in, calories out” method doesn’t add up and explores how factors like genetics, brain signals, and gut health play a major role in shaping our weight. Giles Yeo is a Professor of Molecular Neuroendocrinology at the University of Cambridge and Honorary President of the British Dietetic Association. His research focuses on the influence of genes on feeding behaviour and body weight. Giles is also the author of ‘Gene Eating’ and ‘Why Calories Don’t Count’. Giles shares the surprising impact of ultra-processed foods on how we process calories and why losing weight often feels like a battle against our own biology. With decades of research in his back pocket, Giles shares science-backed advice to help you break free from yo-yo dieting, read calorie labels smarter, and embrace a more balanced, plant-rich diet for long-term health. 🥑 Make smarter food choices.
