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
