    Ep. 525 We’ve Been Misled About Metabolic Health – The Shocking Truth About Cholesterol, GLP-1 & Aging with Dr. Nick Norwitz
    Dec 3 2025
    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.

  • Ep. 520 We Got Healthcare Wrong – The Biggest Flaws in Modern Medicine & How To Fix Them with Dr. Aaron Hartman

    Ep. 520 We Got Healthcare Wrong – The Biggest Flaws in Modern Medicine & How To Fix Them with Dr. Aaron Hartman
    Nov 17 2025
    Today, I am thrilled to reconnect with Dr. Aaron Hartman, a triple-board-certified physician who recently wrote the book "Uncurable." In today’s expansive conversation, we delve deeply into the structural flaws of traditional allopathic medicine. Dr. Hartman shares how his own clinical approach has evolved and recounts Anna’s story, explaining how her experience became a turning point in his professional growth. We highlight the importance of lifelong learning, patient advocacy, and the benefits of removing restrictions to allow providers to deliver patient-centered care. We examine the legacy of the Flexner Report, the rigidity it introduced to modern medicine, and the broad potential of GLP-1s beyond weight loss. We discuss the hidden factors that shape medical errors, the effects of insurance reimbursement, the challenges of existing in the current medical system, and how fear of liability influences clinical decisions. We also explore the triangle of health and the effects of unresolved trauma. This episode is packed with valuable insights, so you will likely want to revisit it more than once. IN THIS EPISODE, YOU WILL LEARN: How traditional allopathic medicine is structurally rigid and limits patient-centered care Dr. Hartman shares how patient advocacy and curiosity-driven learning fueled his clinical evolution. How the Flexner Report created a hierarchy that discourages innovation and integrity The therapeutic potential of GLP-1s beyond weight loss Why being open-minded as a clinician does not mean being reckless How insurance reimbursement models reward overdiagnosis and procedural volume instead of outcomes What the fear of litigation leads to, regarding defensive medicine and unnecessary testing How clinical decisions, overtesting, and overdiagnosis can inadvertently contribute to serious medical errors and harm patients What the triangle of health is, and how it underpins overall wellbeing Why unresolved trauma can cause physical illnesses Connect with Cynthia Thurlow Follow on X, Instagram & LinkedIn Check out Cynthia’s website Submit your questions to support@cynthiathurlow.com Connect with Dr. Aaron Hartman On his website Purchase a copy of Uncurable
