In today’s episode, we have Karan Sarin, author of Sick Nation, breaking down why India is facing a silent metabolic epidemic.

The conversation goes deeper into the coming dementia crisis in India, insulin resistance as a hidden driver of PCOS, and why erectile dysfunction can be an early warning sign of metabolic damage. We also discuss how chronic stress quietly destroys metabolic health, veg vs non-veg diets from a metabolic lens, and the three most important levers to fix metabolic health.

This episode is essential for anyone serious about long-term health, energy, and disease prevention.
