Insulin resistance, excess weight, fatty liver, infertility, and elevated androgen levels – these are clinical features common to two conditions that we wouldn’t necessarily think to connect: polycystic ovary syndrome (PCOS) and hemochromatosis. Interestingly, excess iron is a common finding…
Team DrKF sat down with Dr. Fitzgerald to pose some questions about the “state of the state” of longevity research, current controversies and future directions, and where she sees her work fitting into it. When it comes to defining and…
Dr. Fitzgerald is an internationally-recognized expert clinician, as well as nationally-bestselling author, who is actively engaged in clinical research on epigenetics and longevity using a diet and lifestyle intervention developed in her research and practice.
She has published two clinical studies on the potential bioage-reversing effects of an 8-week DNA methylation-supportive diet and lifestyle in middle-aged men and women in the journal Aging. She continues to lead the conversation around interventions for healthy aging and their extensive potential in improving individual and population level disease burdens, while also providing evidence-based and practical advice that cuts through the hype.
Dr. Fitzgerald is on faculty at the Institute for Functional Medicine (IFM), is an IFM Certified Practitioner, and lectures globally on functional medicine, longevity, and epigenetics to practitioners and consumers.
She maintains an award-nominated podcast series ranked in the top 1% of global podcasts by Listen Score, New Frontiers in Functional Medicine, and an active blog and Clinic Immersion webinar series through her website, www.drkarafitzgerald.com.
