Healthy Aging: Why Exercise Is Non-Negotiable and Protein Is Supporting Cast
New research reframes the protein-first aging model. Exercise is the irreducible core of healthy aging — protein helps, but it doesn't replace what movement does at the cellular level.
Protein Restriction for Kidney Disease: What the Evidence Actually Shows
Peter Attia reviews the MDRD trial and Cochrane data: the default CKD advice to restrict protein lacks the evidence base it's been given — and the biggest trial showed higher long-term mortality in the restriction group.
Aging Research Has Been Studying the Wrong Sex
The Reproductive Resilience Hypothesis, published in Cell, argues female biology holds the key to understanding longevity — but most aging research has treated it as experimental noise.
One Shot, Five Organs: FGF21 Gene Therapy Extends Mouse Healthspan by 20%
A single AAV injection of FGF21 extended median lifespan by over 20% in aged mice, protecting liver, kidneys, heart, muscle, and brain — and it worked after age-related decline had already begun.
Human Longevity's $599 Genomics for All: What Clinical-Grade DNA Sequencing Gets You Now
Human Longevity sequences all 6.4 billion base pairs at $599 — and an AI layer re-alerts you as science evolves. What it covers, who it's actually for, and why the re-analysis matters more than the price.
The Bathroom as a Longevity Clinic: What Vivoo's Passive Monitoring Stack Changes
Vivoo's urinalysis platform and toilet-integrated hydration monitor embed daily biomarker collection into existing routines. What it covers, why passive beats active testing, and where this sits in a complete longevity stack.
NMR Blood Testing: One Blood Sample, Four Different Risk Scores
A single NMR blood scan reveals heart disease, insulin resistance, inflammation, and mortality risk — the inventor explains why one draw beats a standard panel.
Metabolic Health: Why GLP-1s Were Never the Whole Answer
GLP-1 drugs sparked the metabolic health boom, but the platforms building around it are betting the real product is what happens after the prescription.
Niagen's NR Study: A 2.5-Year Drop in Muscle Epigenetic Age
A new peer-reviewed analysis links NR supplementation to a 2.5-year reduction in muscle epigenetic age — though the funding company calls the data preliminary.
Living Near a Data Center Without Wrecking Your Sleep
Data centers bring measurable noise, EMF, heat, and air exposure to nearby homes. A practical framework for measuring and mitigating each risk.
Timeline Wins $5.3M Judgment Against Fake Urolithin A Sellers
A federal court awarded Timeline $5.3M and permanent injunctions against 19 counterfeit urolithin A sellers — a case that signals the longevity supplement market is finally getting real enforcement.
Ultrahuman's Emerald Update Answers a Question Wearables Kept Ignoring
Ultrahuman's Emerald overhaul replaces spreadsheet-style metrics with a decision engine that tells you what to actually do next — plus a VO2 max algorithm validated to lab-grade accuracy.
Peter Attia's Framework for Environmental Threats to Longevity: Air, Noise, and Light
AMA #87 applies Attia's 80/20 principle to chronic environmental exposures — PM2.5, noise, and artificial light — and which interventions actually move the longevity needle.
Heat Training Boosts Hemoglobin — But Can It Make You Faster?
Heat training reliably raises hemoglobin mass by 2–5%. But 5 of 6 trials find no clear performance payoff in VO₂max or sport results. Here's what the evidence actually shows.
Dumbo Health Is Turning Sleep Into a Clinical Longevity Metric — Here's What That Means
Miami-based Dumbo Health launched Sleep Longevity: 51 blood biomarkers, wearable data, and physician care in one membership. The 90% of women with undiagnosed sleep apnea are the real target.
Scientists Reversed 'Permanent' Aging Damage in Human Tissue. Here's What Was Fixed.
A Nature Communications study showed an engineered enzyme (CMLase) removed advanced glycation end products from human arterial, skin, and lens tissue — reversing damage long considered irreversible.
Google's SensorFM: What a 1-Trillion-Minute Wearable Dataset Changes
Google's new foundation model for wearable sensors outperformed prior models on 34 of 35 health tasks — and what it means for the future of passive health monitoring.
Does Losing Sleep Mean Losing Lifespan? What the Meta-Analysis Can't Tell You
A new 79-study meta-analysis links short sleep to 14% higher mortality — but Peter Attia identifies a fundamental problem with the data. Here's what the observational evidence actually proves, and what the controlled research says instead.
The $10 Billion Probiotic Problem: What the Evidence Shows and What Works Instead
The probiotic market generates $10 billion per year despite evidence that most commercial supplements don't persist in the gut. Here's what the studies say—and five mechanistically stronger alternatives.
Dry Fasting for 5 Days: What the Biometrics Actually Showed
A measured 5-day dry fast tracked with continuous glucose, ketones, HRV, InBody scans, and grip strength. What the data showed — and what the dehydration artifact gets wrong.
99% of Probiotics Don't Colonize Your Gut. Here's What Actually Works.
The probiotic supplement market is projected to hit $10 billion by 2028 — and the evidence suggests most products fail to deliver meaningful gut benefits. A breakdown of what the science actually says and five evidence-backed alternatives to consider.
RLT Home TotalSpectrum Panels: Lab-Tested 7-Wavelength Review (2026)
A spectrometer test of RLT Home's ELITE panel measured 70.75 mW/cm² irradiance and 0.7 mG EMF at 12 inches, strong numbers for a full-body panel.
Home Infrared Sauna Buying Guide: The Three Specs That Actually Matter
The infrared sauna market spans $200 blankets to $15,000 cabins. Most buyers choose wrong by focusing on wood and aesthetics. Three specs determine whether a unit delivers results.
