Philosophy of the Plan

Our genes are NOT our destiny. With targeted nutrition, we can decide whether we are living our best life: Whether we’re turning our best genes ON and our worst genes off.

It’s that simple. And the choice is entirely ours. But most of us DON’T take control over our longevity, our healthspan. In the US, most people spend the last 16 years of their lives (16 years!!) with multiple chronic diseases and on multiple medications. In that time, we turn over our hard-earned money to drug companies, hospitals, and extended care facilities so that we can “live” but not really participate in life. It doesn’t have to be this way.

You can live better for longer by turning our best genes ON and our worst genes OFF. This is the science of epigenetics. (epi- above, genetics – our genes) Specifically, we do this by packing each fork full of food with “epinutrients”. These are nutrients that support optimal gene expression via a process called DNA methylation.

“Finally a well-explained, dynamic, science-backed guide to optimizing your health by affecting the core of what makes all of us tick—our genes. I’ve been using Dr. Fitzgerald’s program in my practice for years and I’m so pleased this information is now accessible to all.”

Mark Hyman, MD

Fourteen-time New York Times bestselling author and founder and director of The UltraWellness Center

“A lifestyle program has never been more worthwhile or more revolutionary than Dr. Fitzgerald’s in Younger You. She shows how the simple things like nutrition, exercise, and daily routines can profoundly affect your quality of life—and that it’s never too early or too late for the whole family to start thinking about optimizing their epigenetic expression.”

Sara Gottfried, MD

New York Times bestselling author of The Hormone Cure

“Dr. Fitzgerald has published groundbreaking research that proves that we can change the aging of our body through a specific lifestyle intervention program. Now she has made this program available for all of us to benefit from in this extraordinary book. This is a ‘must’ for anyone interested in what they can do in slowing the aging process naturally.”

Dr. Jeffrey Bland

President, Personalized Lifestyle Medicine Institute



Younger You

Reduce Your Bio Age and Live Longer, Better
Based on the groundbreaking study that shaved three years off a subjects’ age in just eight weeks, discover a proven, accessible plan to prevent diseases and reduce your biological age.

It’s true: getting older is inevitable and your chronological age can only move in one direction. But you also have a biological age, which scientists can measure by assessing how your genes are expressed through epigenetics. Exciting new research shows that your bio age can actually move in reverse—and Dr. Kara Fitzgerald’s groundbreaking, rigorous clinical trial proved it’s possible. By eating delicious foods and establishing common-sense lifestyle practices that positively influence genetic expression, study participants reduced their bio age by just over three years in only eight weeks!
Now Dr. Fitzgerald shares the diet and lifestyle plan that shows you how to influence your epigenetics for a younger you.

The Clinic

Both in-person and telehealth consultations. When working with our physicians, in-person appointments allow us to diagnose and directly treat you. While we don’t take insurance, you may be able to submit costs to insurance for reimbursement and to tax deduct what isn’t covered by insurance.

Telehealth appointments are also available. Although our physicians cannot diagnose or treat you, it is possible to complete a highly detailed investigation, including a history with laboratory analysis, and personalized wellness roadmap. All our nutrition consultations are performed via telehealth.
