Longevity Genes, Blood Biomarkers of Aging, & Targeting Aging with Metformin with Dr. Nir Barzilai

Aging is inevitable, but can we influence how we age? In this episode of Longevity by Design, hosts Dr. Gil Blander and Ashley Reaver, MS, RD, CSSD, interview Dr. Nir Barzilai—the Director of the Institute for Aging Research at the Albert Einstein College of Medicine and the Director of the Paul F. Glenn Center for the Biology of Human Aging Research and of the National Institutes of Health’s (NIH) Nathan Shock Centers of Excellence in the Basic Biology of Aging—during which he discusses groundbreaking research on aging.

This is an enlightening discussion with Dr. Barzilai on factors influencing healthspan and lifespan, and the paradigm-shifting idea of targeting aging to extend healthspan and lifespan. He shares fascinating insights from his research on the influence of genetics and lifestyle on healthspan and lifespan, and blood biomarkers of aging. The conversation sheds light on the emerging evidence for medical interventions (gerotherapeutics) to extend healthspan and lifespan by targeting aging processes.

The episode wraps up with actionable insights for listeners interested in enhancing their healthspan and longevity. Dr. Barzilai discusses the importance of personalized health strategies, integrating cutting-edge research with everyday health practices while emphasizing the importance of a holistic approach. As a listener, you will leave equipped with knowledge and science-backed ways to navigate your personal health journey and help you live healthier longer.
