Video Summary

The webinar, hosted by ACOEM and presented by Dr. Ayesha Chaudhary, introduces lifestyle medicine as an evidence-based approach to preventing, treating, and sometimes reversing chronic disease while supporting longevity and physician wellbeing. Dr. Chaudhary emphasizes that genes account for only about 20% of lifespan; lifestyle and environment influence gene expression through epigenetics. She explains aging mechanisms such as reduced protein “cleanup” and sluggish autophagy, and reviews longevity-related pathways including AMPK activation (via exercise, fasting, coffee), and mTOR inhibition (influenced by diet and activity). She highlights research interest in metformin (TAME/TRIIM-type trials discussed) as a potential anti-aging therapy, though not FDA-approved for that use.<br /><br />Drawing on “Blue Zones” research (Sardinia, Ikaria, Nicoya, Loma Linda, Okinawa), she outlines shared habits: natural daily movement, plant-forward eating (beans as staples, limited meat), the Okinawan 80% fullness rule, stress downshifting rituals, strong social/faith/community ties, and a clear sense of purpose (ikigai). She reviews the six pillars of lifestyle medicine: nutrition, physical activity, sleep, stress management, social connection, and avoiding harmful substances. Evidence cited includes benefits of ~7,000 steps/day, restorative sleep, and lifestyle interventions improving diabetes risk, PSA trends in prostate cancer, and potentially dementia risk reduction. Q&A addressed alcohol guidance, certification, fasting/spermidine, employer ROI, burnout, and metformin use.
