#255: The Wild and Crazy Science on How to Age in Reverse with Dr. Kara Fitzgerald
It’s true: getting older is inevitable and our chronological age can only move in one direction. But we also have a biological age, which scientists can measure by assessing how our genes are expressed through epigenetics.
This week on The Dhru Purohit Podcast, Dhru sat down with Dr. Kara Fitzgerald to talk about the exciting new research that shows that our biological age can actually move in reverse and her groundbreaking, clinical trial that proved it’s possible.
Dr. Fitzgerald received her doctorate of naturopathic medicine from the National College of Natural Medicine in Portland, Oregon. She is on faculty at the Institute for Functional Medicine, and is in private practice in Sandy Hook, Connecticut. Her study Potential Reversal of Epigenetic Age Using a Diet and Lifestyle Intervention: A Pilot Randomized Clinical Trial is the first of its kind to show biological age reversal in humans.
