Most‑Tracked Biomarkers

If you track everything, you learn nothing.

Start with metrics that (1) respond to change, (2) matter to health, and (3) can be measured consistently.

The Short List

Metric Why biohackers track it How to measure What commonly moves it
Sleep timing + total sleep time Drives energy, mood, appetite Diary or wearable Light timing, caffeine timing, stress, late meals
Resting heart rate (trend) Stress/illness/training load signal Wearable or manual Sleep, training load, illness, alcohol
Blood pressure High-signal CV risk marker Home cuff Weight trend, sodium/alcohol, sleep, training
Weight trend + waist Body comp proxy Scale + tape Intake consistency, activity, sleep
HbA1c Long-term glucose control Lab Diet pattern, training, sleep
Lipids (ApoB/LDL‑C) Atherosclerosis risk signal Lab Diet pattern, body comp, meds (clinician)
hs‑CRP Inflammation signal (context) Lab Illness, adiposity, training load, sleep

How to Use This Page

  1. Pick one primary metric that matches your goal: Biohacking Goals
  2. Add 1–3 supporting metrics (to detect confounding)
  3. Run a single-variable experiment: N‑of‑1 Experiments
