Starting my medical journey at 16 and becoming one of the youngest doctors in the country, studying and training at the Mayo Clinic, Harvard Business School, Singularity University and other prestigious institutions, becoming a board certified surgeon and accumulating over two decades of practice, I have discovered that a mere 20% of health knowledge yields 80% of the results. That's why this podcast is all about cutting through the noise on how to turn back the aging clock. I interview world-renowned medical practitioners, doctors, experts, and thought leaders, offering you a step-by-step guide and actionable advice to proactively avoid disease and optimize your health. Plus, I share weekly solo episodes giving you quick, digestible protocols for successfully extending your healthspan.","last_synced_at":"2026-06-09T18:18:24.162936+00:00","page_url":"https://stenobird.com/podcast/extend-podcast-with-darshan-shah-md-7064213"},"episode":{"title":"152.

As research evolves, the conversation is shifting from simple cholesterol numbers toward deeper drivers of cardiometabolic dysfunction. In this episode of Extend, we sit down with Nick Norwitz, metabolic health researcher and physician scientist, to unpack the science behind cholesterol, insulin resistance, and cardiovascular risk. We break down the difference between LDL and ApoB, why insulin resistance may be a stronger predictor of heart disease, how statins work beyond cholesterol lowering, and what emerging research reveals about metabolic health, biomarkers, and individualized risk. We also explore how curiosity driven experimentation, data tracking, and deeper metabolic literacy can help people move beyond simplistic cholesterol narratives and better understand their own cardiometabolic health. Nick Norwitz is a physician scientist and metabolic health researcher who graduated valedictorian from Dartmouth College before earning a PhD in Human Metabolism from the University of Oxford and an MD from Harvard Medical School. Following a personal battle with inflammatory bowel disease, he became a leading voice in metabolic health education and the author of the widely read newsletter StayCuriousMetabolism.com .
