The most rigorous and hedged of the figures graded here — his exercise-longevity and lipid/ApoB science hold up well on independent evidence, largely free of COI. The clearest exception is aggressive whole-body cancer screening, which is both his weakest scientifically supported claim AND the one most tied to Biograph.
Evidence vs. their claims
Across 26 testable claims, where the weight of independent evidence lands — on their side, or against them. Their own research network is excluded as evidence.
Read relative to their stance: when they dispute a claim and the evidence supports that claim, it counts as against them. Each row shows their stance, so you can see which way the evidence cuts.
Conflicts of interest
- Co-founder & Chief Medical Officer of Biograph (longevity diagnostics/screening company) — directly benefits from his aggressive cancer-screening recommendations
- Founder of Early Medical, a concierge longevity practice; book/podcast are a funnel toward paid patients
- Paid advisor/investor in AG1, LMNT, and other supplement/wellness brands
- Notably: publicly reversed his own earlier fasting/TRE advocacy after losing lean muscle mass — a rare documented 'changed my mind' case
Stated factually. Conflicts do not by themselves make a claim wrong; they are context for weighing it.
