Dr Rangan Chatterjee is a practising NHS GP, bestselling author, and television presenter who champions preventive healthcare through simple, sustainable lifestyle changes. Known for his BBC series *Doctor in the House* and his acclaimed TEDx talk, he now presents Channel 4's *Live Well with the Drug Free Doctor* and regularly addresses major healthcare events including The Longevity Show, where he advocates for proactive, personalised medicine that empowers people before disease develops. His latest book, *Happy Mind Happy Life*, focuses on stress management as the cornerstone of wellbeing. Audiences leave his sessions with practical tools to transform their health, energy, and vitality through accessible, evidence-based strategies that prioritise prevention over prescription.

Over two decades of clinical practice have positioned Rangan Chatterjee at the forefront of a healthcare revolution, one that prioritises prevention over prescription and seeks to address the root causes of illness long before symptoms emerge. His conviction that lifestyle medicine should form the cornerstone of modern healthcare has transformed how thousands of patients, practitioners, and audiences understand their relationship with wellbeing. Trained in immunology and a member of both the Royal College of Physicians and the Royal College of General Practitioners, he continues to practise as an NHS GP whilst challenging conventional medical thinking through his media work, writing, and speaking. His TEDx talk, *How to Make Diseases Disappear*, has reached hundreds of thousands of viewers worldwide, and his BBC series *Doctor in the House* introduced millions to his philosophy that simple, sustainable changes can reverse chronic disease. Now presenting Channel 4's *Live Well with the Drug Free Doctor*, set to air in 2026, he examines the UK's reliance on long-term prescribed medication and explores whether alternative approaches can offer greater benefit for patients trapped in cycles of symptom management.

His clinical expertise is matched by a prolific body of work that translates complex science into accessible, actionable guidance. As a bestselling author, Rangan has written extensively on the four pillars of health: relaxation, food, movement, and sleep. His latest book, *Happy Mind Happy Life*, focuses on stress management as the foundation of mental and physical wellbeing, arguing that stress is the single most influential factor affecting health outcomes today. He is also a member of the Institute of Functional Medicine, reflecting his commitment to understanding the interconnected systems that govern human health. His keynote presentation at The Longevity Show 2026 challenged the misconception that modern healthcare truly prioritises health, advocating instead for proactive, personalised medicine based on measuring key metabolic biomarkers and intervening decades before disease develops. This vision has earned him recognition as a trailblazer in preventive healthcare, respected by patients, peers, and policymakers alike.

Rangan equips audiences with practical tools to reclaim control over their health, energy, and vitality. Whether addressing corporate teams, healthcare professionals, or public wellness events, he delivers evidence-based strategies that can be implemented immediately, from morning routines that reduce stress to nutritional changes that stabilise mood and metabolism. His approach is neither prescriptive nor punitive; instead, he empowers individuals to make incremental shifts that compound into lasting transformation. Audiences leave his sessions with clarity about what truly drives wellbeing, inspired by a future where healthcare intervenes before illness takes hold and where simple daily habits become powerful medicine. His message is urgent, hopeful, and profoundly relevant to anyone seeking to thrive in an era where chronic disease has become the norm.
