I’m Rangan Chatterjee, a medical doctor who qualified from Edinburgh Medical School in 2001.

My mission is to help create a more compassionate world by empowering you to be the architect of your own health and happiness, by simplifying complex health information and inspiring meaningful lifestyle change.

I’m passionate about transforming modern healthcare and showing how lifestyle can be our most powerful form of medicine.

I first showcased my philosophy to the public in 2015 in the BBC One documentary Doctor In The House. In that series, I was able to show how many different conditions like type 2 diabetes, anxiety, depression, menopausal symptoms and irritable bowel syndrome could be massively improved and often fully reversed by making small changes to the way we live our daily lives. The show was shown in 70 countries around the world and offered a template to the world as to what modern healthcare could look like in the future.

In January 2026, I released the Channel 4 documentary Live Well With The Drug-Free Doctor where I explored the theme of over-medication and showcased three conditions – type 2 diabetes, chronic pain and depression – which can often be fully reversed without the use of medication.

That is the foundation of my entire philosophy which I detail in my 6 Sunday Times bestselling books on topics like nutrition, movement, sleep, breath work, stress management, habit formation, behaviour change and happiness. I also teach healthcare professionals how to apply these principles with their patients in the Royal College of GPs accredited course I co-founded in 2018, Prescribing Lifestyle Medicine, which has now been delivered to thousands of healthcare professionals around the globe.

For 8 years, I have hosted Europe’s most listened to health podcast Feel Better, Live More which has had more than 350 million listens and helps millions of people around the world improve the quality of their lives on a weekly basis. 

After 23 years of seeing patients, I decided to step away from active clinical practice to focus on transforming the practice of healthcare, teaching healthcare professionals and educating the public as to how they can improve their health and wider lives. I am a Professor of Health Education & Communication at Chester Medical School and have recently co-founded, Do Health, a personalised health companion, that I believe will be the future of preventative health in the UK and many countries around the world.

No matter who you are or what challenges you face right now, I promise that you have the ability to make meaningful changes that last.

Making lifestyle changes is always worth it because when you feel better, you live more.

And, always remember, it starts with you.
