In this episode, Dr. Ronesh Sinha, a physician, author, and educator based in Silicon Valley, shares his many insights into metabolic illness that he has gleaned from his South Asian patient population. In this conversation we focus on hyperinsulinemia, insulin resistance, metabolic dysregulation, inflammation, blood pressure, obesity, etc. and ways to address them with nutrition, sleep, exercise, stress management, and more. We also take a deep dive into insulin resistant phenotypes, evolutionary theory and geographic determinants of insulin resistance which provides insight into the genetic architecture and pathophysiology of metabolic syndrome. Additionally, we discuss the surprisingly interrelated topic of stress, and how we might be inadvertently passing this on to our children, leading to mental and physical sickness down the road.
We discuss:

- Mechanistic explanations of insulin resistance (there may be more than one) [35:15];
- Theories on origins and evolutionary reasons for insulin resistance [40:00];
