Peter Attia has become the physician other physicians quote when the topic turns to longevity, and across his appearances on The Tim Ferriss Show and Huberman Lab he rarely repeats himself. Each conversation cracks open a different corner of his practice: cancer screening math on one show, hormone replacement therapy on another, a full teardown of the supplement industry on a third. We pulled every episode of his in our library and ranked them by how much new, specific information actually got said out loud.
Below are all five appearances, most information-dense first, with the guest and topic noted so you can find the angle you actually want. If you only have time for one, start at the top. If you're already deep into the longevity rabbit hole, the ApoB and hormone episodes fill in gaps the others skip.
Dr. Peter Attia — Longevity Drugs, Alzheimer's Disease, and More
This is Attia at his most freewheeling, running through Ferriss's 'excited about / changed my mind about / absurd' format across nearly three hours. He explains why Grail's liquid biopsy cancer screening excites him more than almost anything else in medicine, breaks exercise into four pillars starting with stability, and lays out the data on rapamycin extending mouse lifespan by 11-19% in the NIH's rigorous testing program. He also walks through his own close reading of the psilocybin-vs-Lexapro NEJM trial, arguing it was underpowered rather than a true negative. Listen if you want the widest-angle view of his thinking, plus a mini-course in how to actually read a clinical study.

Built around his book, this episode gets personal fast: Attia describes the DEXA scan that showed how much muscle a decade of extreme fasting had cost him, and how he rebuilt 13-14 pounds of lean mass in a year through protein timing and hypertrophy work. The centerpiece is his finding that moving from the bottom 25% of fitness to just the 25th-50th percentile cuts all-cause mortality roughly in half, a bigger effect than any drug he's found. It closes with a rare, vulnerable account of the 47 self-affirmations he wrote in rehab. Best for listeners who want the Outlive thesis straight from the source, muscle math and all.

Huberman gets Attia into clinic mode here, and the biomarker detail is the deepest of any episode on this list: ApoB as the sole number he treats for cardiovascular risk, why power lifting beats running for bone density, and a blunt call-out of the mishandled Women's Health Initiative study as 'the biggest screw up' in recent medicine. He also details his own testosterone protocol and why 80% of his patients over 45 end up on a statin. This is the one to send anyone asking which blood tests actually matter.

Attia works systematically through the leading causes of death (atherosclerosis, cancer, neurodegeneration, and now fentanyl-driven accidents) before pivoting to something he rarely discusses in this much depth: his own rock-bottom stays in rehab facilities in 2017 and 2020, decades of unexplained rage, and the therapy exercise that finally quieted his inner self-talk. He also discloses he's been on a PCSK9 inhibitor since 2015. Worth it for the emotional-health section alone, which most longevity content skips entirely.
Read the full episode notesSupplements for Longevity & Their Efficacy | Dr. Peter Attia
Attia and Huberman spend two-plus hours methodically dismantling the case for NAD-boosting supplements, tracing the science from sirtuin overexpression in yeast through resveratrol's collapse and NR's failure in the Interventions Testing Program. Their conclusion: 'the answer appears to be unambiguously no' on lifespan extension, with Attia flatly stating he doesn't take them himself. He contrasts this with rapamycin, which he does take and calls his personal turning point in the field. Send this to anyone currently buying NMN.
