About this course

Methylation is the primary mechanism of epigenetic expression and also a novel way to measure ageing. For the first time, this process has been researched in relation to the effects of diet and lifestyle modifications. In this course, Dr Kara Fitzgerald shares the clinically-useful learning from this pioneering study that she led.

In this presentation, Kara Fitzgerald delivers an exciting update on the process of methylation and its effects on epigenetics. Her recently completed study, published in the journal "Ageing", was able to reverse biological age in older adult men by 3.24 years in just eight short weeks as compared to the control group. This is the first randomised, controlled clinical trial to show specific diet and lifestyle interventions reverse epigenetic ageing in healthy adult males.

What is even more exciting, the trial did not use any expensive supplements or risky biohacking to produce their results. The only interventions were straightforward dietary changes and simple lifestyle practices.

Ageing is the number one risk factor for chronic disease and this seminal study is pioneering a new understanding in natural medicine. Learn the latest on methylation, epigenetics, ageing and chronic disease.

Dr Kara Fitzgerald N.D

Kara Fitzgerald, ND, received her doctor of naturopathic medicine degree from the National University of Natural Medicine in Portland, Oregon. She completed the first Counsel on Naturopathic Medicine-accredited post-doctorate position in nutritional biochemistry and laboratory science at Metametrix Clinical Laboratory (now Genova Diagnostics) under the direction of Richard Lord, PhD. Her residency was completed at Progressive Medical Center, a large, integrative medical practice in Atlanta, Georgia.

Dr. Fitzgerald is the lead author and editor of Case Studies in Integrative and Functional Medicine and is a contributing author to Laboratory Evaluations for Integrative and Functional Medicine and the Institute for Functional Medicine (IFM)’s Textbook for Functional Medicine. With the Helfgott Research Institute, Dr. Fitzgerald is actively engaged in clinical research on the DNA methylome using a diet and lifestyle intervention developed in her practice. The first publication from the study focuses on reversal of biological aging and was published 04-12-2021 in the journal Aging. A consumer book and application-based program with DNA methylation assessment are scheduled for release 01-2022.

Dr. Fitzgerald is on the faculty at IFM, is an IFM Certified Practitioner and lectures globally on functional medicine. She runs a Functional Medicine Clinic Immersion program for professionals, and maintains a podcast series, New Frontiers in Functional Medicine and an active blog on her website, Her clinical practice is in Sandy Hook, Connecticut.
