“People think I’m anti-physics. I’m not anti-physics. Calories don’t give you the information to improve your diet.” Dr Giles Yeo is a geneticist at Cambridge University specialising in obesity and how our brain controls food intake. He’s also the author of ‘Why Calories Don't Count’ and ‘Gene Eating’. In this episode Giles and I dig into the science of genetics and hunger hormones and why some people struggle with their weight more than others. I also challenge him on the notion that calories don’t count. Stay tuned to find out: ➡︎ How over 1000 genes are involved in body weight and controlling your appetite ➡︎ Why obesity isn’t a moral failing and should be thought of as a disease ➡ The huge variety in how different ethnicities are impacted by obesity ➡︎ What exactly “calories don’t count” really means ➡︎ Why fad diets should be ignored and how to find the diet that works for YOU Connect with Giles: Instagram: https://www.instagram.com/gilesyeo/ X: https://x.com/GilesYeo Grab Giles’ book here: https://amzn.eu/d/hoAnVLr For more useful science for your everyday life, grab my best selling book “This Book May Save Your Life”: https://geni.us/DrKaranBook An OG Podcasts production. #DrKaran #MedicalScience #HealthEducation #HealthTips Don't miss an episode!
