Interview Questions
Can aging actually be reversed?
Sinclair explains that aspects of aging are programmable and, in animal models, partially reversible. His lab showed that epigenetic noise contributes to aging and that partial reprogramming with specific Yamanaka factors restored vision in old mice. He emphasizes this is not wholesale reprogramming to pluripotency, but targeted, cyclic protocols that reset cellular identity without tumorigenesis in controlled settings.
What practical steps support longevity according to his research?
He highlights evidence-backed pillars: regular exercise (especially intensity and muscle work), time-restricted eating and periods of low caloric intake, plant-forward diets with low sugar and refined starches, sufficient sleep, temperature stress (cold/heat), and avoiding smoking and excess UV. He discusses NAD+ and sirtuin pathways, noting lifestyle triggers are foundational while supplements require medical guidance and individual risk assessment.
What role do NAD+ boosters, resveratrol, and metformin play?
Sinclair has discussed research on NAD+ precursors (like NR/NMN) that elevate cellular NAD+ and support sirtuin activity, and resveratrol as a SIRT1-activating compound in certain contexts. He has spoken about metformin’s links to metabolic health and longevity signals, while stressing that non-diabetics should consult physicians and consider potential trade-offs with high-intensity training. He avoids making personal recommendations and underscores ongoing, evolving evidence.
Is there a single “longevity pill” on the horizon?
He cautions that no single pill replaces the synergy of lifestyle, prevention, and—eventually—combinations of therapeutics. He expects the future of longevity to blend behavioral interventions, biomarkers to track biological age, and targeted therapies (from epigenetic reprogramming to metabolic modulators) validated by rigorous clinical trials.
How does he measure progress toward a longer healthspan?
He advocates tracking objective markers: resting heart rate, VO2 max, strength, glucose control, lipid profiles, inflammation markers, sleep quality, and emerging biological age clocks (epigenetic and proteomic). He advises focusing on trends over time and pairing metrics with sustainable habits rather than quick fixes.
