Weight loss drugs may increase human longevity but that's because they reduce the mortality of folks at the lower end of the lifespan distribution (i.e., unhealthy individuals), not because they delay the aging process. That's still valuable, but if this is the best intervention we have, it reflects poorly on current aging science. At best, weight loss drugs are targeting aging accelerants, not aging per se. To truly increase longevity, we need interventions that reduce mortality for everyone by targeting aging.
We talk a lot about brain aging as if it’s inevitable. It’s not. In my latest podcast conversation with @DrRagnar—author of The Stimulated Mind—we unpack what’s actually working for brain longevity and what isn’t. A few takeaways that stood out to me: • The...
The question is no longer if we can intervene in aging. It’s how safely and how many times
I thought this was an excellent, balanced article on the current state of unapproved peptides from a safety and regulatory perspective by @AnjeanetteDamon in @propublica https://t.co/DbA8cdvTY5 The fundamental problem is that we don't have quality data on safety or efficacy for...
As a medical school professor, the protein recommendation I was taught -- 0.8 g/kg body weight -- is actively harming older adults. New data proves it. A 2025 Frontiers in Nutrition trial randomized 126 elderly women with sarcopenia into two groups...
I think that it is easier to measure Peakspan than Healthspan. And something we should study hard. I don't want just healthspan - I want to be at my peak. Not for myself but for all of you - we...
Longevity testing starter pack: 1. VO2 max/Cooper test - cardiorespiratory fitness 2. Grip strength - muscle mass and strength 3. Blood pressure - cardiovascular disease risk 4. DEXA scan - muscle and bone density 5. Blood panel - a dozen most common blood markers 6. Waist...
Meet Dr. Mark Woodward, undergrad and grad from Stanford, PhD from Harvard, Many years at Google as part of Google brain. One day he realizes that we need the enabling technology to pause biological time for patients that are about...
I've measured my body a lot. I'm about to dwarf what we've done by building real-time continuous multi-omic monitoring and intervention. Cars drive themselves. Software writes itself. I'm building Autonomous Health. First for me, then for you. > Peptides...
What's your biological age? Experts explain the benefits and risks of at-home tests https://t.co/NSr8O4EGnU via @nbcnews
Here's my take on your paper: Cellular senescence or "zombie cell" events happen when a cell experiences too much genetic or epigenetic noise, caused by cellular damage (e.g. DNA breaks) or telomere erosion Your study of a Lewis Lung Carcinoma (LLC) mouse...
Could a plant-based diet make your bones weaker? In this meta-analysis that looked at 529,672 participants (average ages of 46–63; 57% women, 43% men), both vegetarian diets and vegan diets were associated with a HIGHER risk of hip fracture: https://t.co/3u18PxPmrk...
I think I need to be fired. I've done 232 dry sauna sessions. Last week I confirmed, for the first time (by swallowing a pill), whether the core temperature threshold that gates the primary cellular repair mechanism was actually being reached in...
CRAZY IF TRUE PAPER: A new study in mice reports that resveratrol intake by old male mice (or directly treating their sperm) changes the metabolism of embryos & pups, "potentially through alterations in sperm telomere length and epigenetic modifications"...
As a medical school professor, I have watched vitamin D research for decades. This trial finally delivers causal evidence. The VITAL randomized controlled trial -- the gold standard -- followed nearly 1,000 adults aged 50+ for 4 years and found that...
