Why We Get Sick: The Hidden Epidemic at the Root of Most Chronic Disease and How to Fight It

Aug. 20, 2021

Benjamin Bikman, PhD is an internationally renowned scientist and pathophysiology professor at Brigham Young University in Provo, Utah. Currently, his professional focus is to better understand the origins and consequences of metabolic disorders, including obesity and diabetes, with a particular emphasis on the role of insulin. He frequently publishes his research in peer-reviewed journals and presents at international science and public meetings.

On this podcast, Ben talks with NBT Scientific Director Megan Hall about insulin resistance: what causes it, how it develops in the body, and the downstream effects of this all-too-common condition. Ben discusses the role of insulin as a regulator of human metabolism and its relevance in the development of most chronic diseases. He also offers a simple and effective prescription for optimal metabolic health and healthy ageing.
