About this episode

Haylie Pomroy interviews Dr. Lubov Nathanson about the impact of lifestyle on gene expression and the concept of epigenetics.

In today's episode, Haylie Pomroy sits down with Dr. Lubov Nathanson, Director of the Genomics Group at the Institute for Neuro Immune Medicine, to break down one of the most misunderstood and misused words in health right now: epigenetics. Dr. Nathanson explains the difference between genetics, the fixed sequence of nucleotides in our DNA, and epigenetics, the vast set of factors that regulate which genes are expressed without changing the sequence itself. She walks through why the overwhelming majority of chronic diseases are not single-gene disorders but polygenic conditions. Her core message is as clear as it is empowering: genetics loads the gun, epigenetics pulls the trigger. If you have ever said "it runs in my family" and believed that settled it, this episode is for you. Tune in to Fast Metabolism Matters.
