In this episode of The Longevity Leaders, Dr. Kara Fitzgerald dives deep into her groundbreaking work on how we can slow—and even reverse—biological aging through the lens of epigenetics. She explains the difference between chronological and biological age and reveals that what we eat and how we live can influence our gene expression for the better. She also introduces a program, backed by peer-reviewed research, that demonstrates how simple diet and lifestyle changes can roll back biological age by three to four years in just eight weeks.
Dr. Fitzgerald unpacks the role of certain nutrients found in colorful vegetables, herbs, spices, and quality proteins like liver and eggs. She also emphasizes how powerful everyday habits can help optimize gene expression. This episode is a hopeful reminder that aging is not entirely out of our hands and that functional medicine’s foundational wisdom is finally being validated by cutting-edge science.
