Long-term health notes from Lucas
Lucas reads about health the way a ledger-keeper tracks accounts — carefully, over time, with notes. He shares what he finds: what the research actually says, what changes on a longer view, and what he is currently paying attention to.
01 / A note from Lucas
I started keeping health notes the way I keep financial records: methodically, with dates, in a format I can return to later and still understand. Most health writing moves too fast. A study appears, a headline gets written, a conclusion is drawn before the replication is in. I wanted a slower read.
So I built a ledger. Not a protocol, not a plan — just a structured record of what I read, what changes over time as more evidence accumulates, and what I am currently paying attention to. Each dispatch is an entry in that ledger, shared.
I do not issue recommendations. I track observations. The ledger is the point.

02 / What the ledger tracks
LHL-01
What the research on sleep quality says, revised as it changes. Not sleep hygiene tips — the underlying mechanics and what the longer studies show.
LHL-02
Evidence on food and metabolic health at the ten-year timescale. What flipped, what held, what the meta-analyses actually found when revisited.
LHL-03
Grip strength, VO2 max, resting heart rate, muscle mass over decades. How each ages, what the research says about the levers worth pulling early.
LHL-04
Stress physiology, attention, cognitive reserve across age. The intersection with physical health — increasingly the more interesting side of the ledger.
From the reading desk.
The interesting question is not what is good for you. It is what is still true about health in ten years. That question requires a ledger, not a headline.

03 / Past entries
What the long-term sleep studies revised in 2024
Six hours vs. eight — and why the framing was always wrong.
Zone 2 training: where the research stands now
Three years of updated cardiology meta-analyses, compressed into a ledger entry.
Grip strength as a longevity signal: what the literature actually says
How one simple measure became the most replicated predictor of healthspan.
On reading health research: a short guide to not being fooled by yourself
Confounders, surrogate endpoints, and why n=1 is both useless and necessary.
Protein intake in middle age: where consensus has moved since 2020
The updated RDA argument and why most recommendations still lag the evidence.
Good health reading is slow reading. The question is not what is optimal. It is what the evidence looks like without the press release.

Free. Irregular.
Health notes, updated as the evidence changes. No urgency, no protocol. Just Lucas reading carefully and writing it down.
