David Sinclair

Professor of Genetics, Harvard Medical School · Author, Lifespan

Aging is an information problem — the body loses the epigenetic instructions that tell cells how to function. Sinclair's protocol targets NAD⁺ restoration, sirtuin activation, and mTOR suppression to slow the loss of that information and, in animal models, partially reverse it.

Tier I = multiple RCTs in humans · Tier II = human trials, early stage · Tier III = mechanism / animal studies only

Lifestyle Pillars

1Intermittent fasting (skips breakfast, eats in a 6–8 hour window)
2Vigorous exercise 3–5× per week including HIIT and resistance training
3Cold exposure — cold showers or ice baths 2–3× per week
4Avoids excess protein (mTOR suppression) — plant-forward diet
5Tracks biological age using epigenetic clock tests (Horvath, GrimAge)
6Minimises sugar and refined carbohydrates
7Prioritises 7–8 hours of sleep

Important Caveats

Metformin and statins are prescription medications. Sinclair's protocol is a self-experiment, not a clinical recommendation. The TAME trial (Targeting Aging with Metformin) is ongoing and will provide higher-quality evidence. Resveratrol bioavailability in humans remains debated; the SIRT1 activation mechanism is contested.
