Intelligent Medicine

Dr. Kara Fitzgerald is the author of a landmark study that demonstrates conclusively that lifestyle impacts, not just disease, but the aging process itself. It does so via epigenetic modification, the mechanism by which environmental factors orchestrate the expression of genes. Dr. Fitzgerald has incorporated her findings in a new book "Younger You: Reduce Your Bio Age and Live Longer, Better." She details how diet, sleep, exercise, stress reduction, and avoidance of toxic chemicals can slow, and even reverse, our biological clocks. The key is DNA methylation, which can be assessed via commercially-available saliva test kits. Dr. Fitzgerald lists specific supplements that may augment the benefits of a low-carb, plant-rich diet incorporating high-quality animal protein. Her pioneering research validates the far-reaching benefits of natural lifestyle interventions.
