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.
