Dr. Kara Fitzgerald on How to Become a Younger You by Reversing Your Biological Age
You can lower your bio age

In today’s episode of Passion Struck with John R. Miles, I interview Dr. Kara Fitzgerald about her groundbreaking work in understanding how you can reverse your biological age and become a younger you. | Brought to you by Gusto. Go to (  for three months free.

Quote from Dr. Kara Fitzgerald from the Passion Struck podcast: "We are in this revolution in medicine, that's as revolutionary as the Industrial Revolution. We're able to see what's happening at the genetic level, we can look at genetic expression."

Dr. Kara Fitzgerald, ND, IFMCP, is the first-ever recipient of the Emerging Leadership Award from the Personalized Lifestyle Medicine Institute in recognition of her work on DNA methylation. Dr. Fitzgerald directs a large, integrative in-person and virtual clinical practice in Connecticut. She is engaged in clinical research on the DNA methylome using a diet and lifestyle intervention developed in her clinic. Her first study was published in the journal Aging. Earlier this year, she published Younger You: Reduce Your Bio Age and Live Longer, Better, an application-based program based on the study.

What is Biological Age?

There is a link between aging and chronic disease, and it has everything to do with epigenetics and their effect on aging. Biological age looks at specific patterns of a critical epigenetic mark called DNA methylation. These DNA methylation patterns can reliably predict how fast our body is aging. Methylation is as essential to our bodies as breathing and is happening in our bodies and within our cells all of the time. Therefore, if you can give yourself the DNA methylations of a younger you, you can reset your biological aging process.

It’s up to you. It’s up to how you live your life, which influences what genes are on and what genes are off. This is wildly important for us to understand and embrace this reality. Because we have to take responsibility for our health, we absolutely do.

What I Discuss With Dr. Kara Fitzgerald About Her Book About How to Reverse Your Biological Age

Dr. Kara Fitzgerald and I discuss how she challenges the long-held concept that we are helpless due to the decline in our physical health as we age. She provides the consequences of living the standard American life and the alternatives that can change our destiny as it relates to how we age and, more importantly, how we can reset our clock and reduce our biological age.

  • Why do most adults spend the last 16 years of their lives suffering from chronic conditions and taking multiple medications?
  • Why reversing biological age is key.
  • Why it’s epigenetics and not your genetics that determines your level of health and age
  • How is epigenetic expression greatly influenced by DNA methylation?
  • How do our diet and lifestyle choices impact DNA methylation?
  • The results of her research and a groundbreaking clinical trial showed a reduction of biological age by three years.
  • Why it is our daily choices and routines that add years to your life or reduce them
  • Her diet and lifestyle program which increases healthspan and reduces your biological age.

More From My Interview With Dr. Kara Fitzgerald On How to Become a Younger You

During our interview, I asked Dr. Kara Fitzgerald about the revolution in medicine and its impact on epigenetics and biological age.

Younger You by Dr. Kara Fitzgerald about reverse aging and biological age

Dr. Fitzgerald explains, “So this extraordinary ability to see is by Naturopathic training is this deep appreciation of how we evolved and what works best with us: how we eat, how we should eat, how we should live, how we interact with our fellow humans, et cetera. This very grounded, traditional naturopathic education layered onto the training and the ability to see how this influences our lives.

So then flash forward to biological age. We measure the biological age by looking at what genes are on and off, which is amazing. This is the field of epigenetics above the genes. It’s the interaction of biochemical markers that turn genes on and off. Those biochemical markers are influenced by how we live our lives. So here’s our genes. They’re not changing. We got what we got. They don’t influence our health like we think that they do. They don’t influence longevity like we think they do.

These are huge points that we have to underline if you think you’re going to live long and fabulous because your parents did or your grandparents did. Your genes might be a 10 to 20% effect on your longevity. Likewise, if your family was horribly sick, nope, you don’t necessarily inherit that. It’s up to you. It’s up to how you live your life, which influences what genes are on and what genes are off.

This is wildly important for us to understand and embrace this reality because we have to take responsibility for our health. We absolutely do.”
