Ep. 525 We’ve Been Misled About Metabolic Health – The Shocking Truth About Cholesterol, GLP-1 & Aging with Dr. Nick Norwitz

I am thrilled to reconnect with Nick Norwitz today. Nick is a researcher and educator with a mission to make metabolic health a mainstream concern. He graduated valedictorian from Dartmouth College, completed his PhD in metabolism at the University of Oxford, and earned his MD at Harvard Medical School. He has become known as a clinical researcher and metabolic health educator, speaking and writing on various topics, including brain health, microbiome, mitochondrial function, cholesterol, and more.  In our conversation, we discuss the challenges of providing evidence-based medicine, and Nick shares his personal story of overcoming inflammatory bowel disease with a ketogenic diet. We explore the research on statins reducing endogenous GLP-1 production, highlighting the importance of staying curious. We also clarify the different types of type 2 diabetes, the effects of biomolecular aging, and different perspectives on Lp(a).  Nick always provides thoughtful and valuable insights on a range of topics. His Substack is one of my favorites, sharing several ways to enhance your learning process, as a clinician or a layperson. IN THIS EPISODE, YOU WILL LEARN: How his struggle with inflammatory bowel disease led Nick to realize that the evidence-based care of western medicine is not always the best type of care, and how a ketogenic diet saved his life How a recent study highlighted several major physical issues statins cause, yet it went largely unnoticed in medicine and the media The need for clinicians to inform their patients about the potential side effects of their medications How physicians tend to ignore evidence in favor of one-sided messaging that erodes trust and undermines informed care The importance of remaining curious and acknowledging that what you learned initially might be incorrect How technological advances will make personalized medicine the future of healthcare The limitations of traditional one-size-fits-all randomized controlled trials The sub-phenotypes of type 2 diabetes How enzyme inhibitors (like statins) disrupt the gut microbiome How metabolic health and oxidative stress affect Lp(a), and how vitamin C can potentially reduce its impact Bio: Nick Norwitz Nick Norwitz, MD, PhD, is a researcher-educator whose mission is to “Make Metabolic Health Mainstream.” He graduated Valedictorian from Dartmouth College, majoring in Cell Biology and Biochemistry, before completing his PhD in Metabolism at the University of Oxford and his MD at Harvard Medical School.  Nick has made a name for himself as a clinical research and metabolic health educator, speaking and writing on topics ranging from brain health, the microbiome, and mental health to muscle physiology, mitochondrial function, and cholesterol and lipids.

I am excited to reconnect with Dr. Tom Dayspring today. He joined me before for an extremely popular seven-part podcast series where we tackled topics related to lipids and the physiological shifts that occur as we transition from perimenopause into menopause. Dr. Dayspring graciously agreed to return today for an Ask Me Anything episode, where we explore how lipids change as we navigate the perimenopause-to-menopause transition and discuss the significance of bioindividuality, inflammation, vascular health, and endothelial function in the context of changing estrogen levels. Dr. Dayspring also clarifies how visceral fat affects lipid levels, and we discuss testing for cardiovascular disease, the relevance of particle size, LPIR scores, and physical markers of insulin resistance.  Stay tuned for today’s valuable and fascinating conversation.
