In this episode of the Flipping 50 podcast, host Debra Atkinson welcomes Dr. Kara Fitzgerald, an award‑winning functional‑medicine clinician and author of Younger You. The conversation opens with a sponsor plug for Blue Sky CBD sleep gels, then moves into Dr. Fitzgerald’s journey into epigenetics and the development of her 8‑week diet‑and‑lifestyle program that has been shown in a controlled clinical trial to reverse biological age by more than three years. She explains the science of DNA methylation, how environmental factors such as food, exercise, stress, and community influence gene expression, and why these changes matter for longevity and disease risk. Practical recommendations are shared: a protein‑rich, polyphenol‑dense, mushroom‑inclusive diet (with both animal‑based and vegetarian options), a minimum of 30 minutes of exercise five days a week at 60‑80 % perceived exertion, and the importance of resistance training and HIIT while avoiding over‑training. The hosts discuss the nuanced debate around animal versus plant protein, the role of joy, oxytocin, and social connection in epigenetic resilience, and tools for tracking progress—including the Oura Ring, biological‑age testing, and a free online quiz. Throughout, Dr. Fitzgerald emphasizes individualization, the need for sustainable habits, and the promise of epigenetic diagnostics beyond biological age.
