Preventive health has long been under-prioritised and under-discussed. In this episode, we sit down with Dr. Karan Rajan — NHS surgeon, #1 Sunday Times bestselling author, and one of the UK’s most trusted health communicators — to explore the habits, decisions, and knowledge that can transform your long-term health. From tackling health misinformation and the basics of disease prevention, to wearable technology, fertility, and his own personal battle with high cholesterol and fatty liver disease, Dr. Rajan cuts through the noise with the kind of clarity that is rare in an age of conflicting advice. Whether you have ever wondered what you should actually be doing to protect your health, or what the future of preventive healthcare looks like, this is exactly where you start.
