True health goes beyond prescriptions and tracking scores. Dr Rangan Chatterjee reveals how modern medicine often creates dependency, why stress can mirror the effects of poor diet, and how ownership, self-trust, and daily stillness can rebuild lasting wellbeing. Every meaningful change begins with agency.
“Biohacking is about agency and empowerment. So much of modern medicine is about dependency and disempowerment.” – Dr Rangan Chatterjee
Dr Rangan Chatterjee is one of the UK’s most recognised medical voices and a leading figure in lifestyle medicine. He is the host of Feel Better, Live More, the most listened-to health podcast in the UK and Europe, reaching over eight million listeners each month. He is the author of six international bestsellers, including Make Change That Lasts, and the creator of BBC One’s Doctor in the House, viewed in more than 70 countries.

In this conversation, Tim and Rangan explore:
➡︎ Agency and Empowerment: Why medicine often creates dependency, how consultation styles shape patient outcomes, and the simple reframing that restores ownership of health.
➡︎ Stress and Blood Sugar: How emotional and psychological load can elevate glucose levels as powerfully as food, and what practical steps bring them back into balance.
➡︎ Wearables with Purpose: How continuous glucose monitors and other trackers help when used for insight, not identity, and why self-awareness matters more than data.
➡︎ The Hidden Cost of Optimisation: How chasing perfect metrics can disconnect us from relationships, purpose, and the joy that sustains long-term health.
➡︎ Daily Practice and Self-Trust: The 3 Ms, Mindfulness, Movement, and Mindset, as the foundation for consistency, balance, and meaningful progress.
