We've all heard the saying that our genes determine our destiny. If your parents died in their early seventies, that means you are more likely to die in your seventies. A family history of chronic disease means you're more likely to get it.

Even obesity is blamed on our family tree. Well, our guest today, Dr. Kara Fitzgerald says it's not genetics that determines our age and level of health, it's our epigenetics. Research shows by using diet and lifestyle modification, we have the innate ability to reverse our biological age.

Dr. Fitzgerald is a doctor of naturopathic medicine and an Institute for Functional Medicine Certified Practitioner.

She's the lead author and editor of case studies and integrative and functional medicine and became the first-ever recipient of the Emerging Leadership Award from the Personalized Lifestyle Medicine Institute, as a leading voice in the intersection of nutrition epigenetics and aging. Her new book is called "Younger You: Reduce Your Bio Age and Live Longer and Better."
