Dr Karan Explores Do Your Genes Make You Fat? With Dr Giles Yeo
💬 “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
