How To Reverse Your Biological Age with Dr. Kara Fitzgerald

Jan 19, 2022

Dr. Kara Fitzgerald, a naturopathic doctor and functional medicine expert, shares groundbreaking insights on reversing biological age. She discusses how simple lifestyle and dietary changes can potentially take years off your biological age in just weeks. Emphasizing the significant role of methylation, she reveals how specific nutrients, like B vitamins, can influence health outcomes. The conversation touches on the concept of longevity escape velocity, urging viewers to rethink aging as a treatable condition rather than a decline, making health optimization achievable for everyone.

Episode notes

INSIGHT

Reversing Biological Age

Biological age, unlike chronological age, can be reversed.
This reversal is achievable through changes in the epigenome, which regulates gene expression.

INSIGHT

Methylation Explained

Methylation, a biochemical process, regulates gene expression.
Methyl groups are transferred by S-adenosylmethionine (SAMe) to impact various bodily functions.

ANECDOTE

The Agouti Mouse Study

Dr. Hyman describes Randy Jirtle's experiment with agouti mice.
Genetically identical mice had different health outcomes based on methylation factors.

What if I told you it was possible to reverse your age by three years, in just eight weeks? Well, it is, and today you can learn how. Perhaps the greatest part of this exciting news is that the changes we can make to reverse biological aging are pretty simple and very accessible. The amazing doctor behind this groundbreaking research is my good friend, colleague, and long-time collaborator Dr. Kara Fitzgerald.

Dr. Fitzgerald is on the faculty of the Institute for Functional Medicine, is an IFM Certified Practitioner, and lectures globally on Functional Medicine. She runs a Functional Medicine Clinic Immersion program for professionals and hosts a podcast series, New Frontiers in Functional Medicine, and an active blog on her website. Her clinical practice is in Sandy Hook, Connecticut. 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 the reversal of biological aging and was published this past April in the journal Aging. Her new book, Younger You, as well as her 3 Years Younger Program, have just been released.
