¶ Baseline & Measurement Setup
The #1 biohacking mistake is changing too much too fast.
A baseline turns “I feel better” into a measurable claim you can verify.
¶ Baseline Checklist (2–4 Weeks)
Track the boring stuff first — it explains most variability.
¶ Daily (minimal)
- Sleep: bedtime, wake time, total sleep time (and a subjective sleep quality score).
- Activity: steps (or minutes of intentional movement).
- Stimulants: caffeine amount + cutoff time.
- Nutrition: meal timing + any outliers (late meals, alcohol, unusually high carbs).
- Subjective: energy (1–10), mood (1–10), stress (1–10).
¶ Weekly
- Body weight (trend, not day-to-day noise).
- Resting heart rate (trend) and blood pressure (if you have a cuff).
- Training volume summary (minutes of cardio, strength sessions).
¶ One-time setup
- A clear goal (pick one primary outcome to optimize): see Biohacking Goals.
- A tracking cadence: what you’ll measure daily vs weekly vs monthly.
- A safety plan: see Red Flags.
¶ The Measurement Stack (Minimal → Advanced)
| Tier | What you measure | Typical tools | What it’s good for |
|---|---|---|---|
| Tier 0 | Sleep/time, steps, weight, BP (optional), subjective scales | Phone + scale + (optional) BP cuff | Most of the signal with almost no friction |
| Tier 1 | HR/HRV trends, sleep consistency | Wearable (ring/strap/watch) | Detecting stress, recovery, and sleep regularity changes |
| Tier 2 | Labs (metabolic + lipids + inflammation) | Lab panels 1–2×/yr | Verifying longer-term physiological shifts |
| Tier 3 | Continuous sensors + body comp imaging | CGM, DEXA, VO₂max testing | Deep dives and high-resolution experiments |
Accuracy note
Wearables are usually best for trends (changes over time), not absolute truth. Use consistent placement and don’t over-interpret sleep staging.
¶ Core Labs (Common Starting Point)
This is not medical advice and it is not a prescription for testing. It’s a pragmatic “starting list” many people use to anchor biohacking decisions — your clinician may add/remove items based on age, symptoms, medications, and risk factors.
¶ Common baseline panel
- CMP (comprehensive metabolic panel)
- CBC (complete blood count)
- Lipids (consider ApoB if available)
- HbA1c and/or fasting glucose
- hs‑CRP (inflammation signal)
- TSH (thyroid screening context-dependent)
- Vitamin D (especially if low sun exposure)
¶ Optional, based on goals
- Ferritin, B12, folate (fatigue/anemia pattern checks)
- Fasting insulin (insulin resistance context)
- Omega‑3 index (dietary fats; availability varies)
- Sex hormones (symptoms and clinical context matter)
Screening guidance exists — use it
If your “biohacking” is really screening for disease risk (diabetes, hypertension, cardiovascular risk), anchor decisions in evidence-based screening recommendations and discuss results with a clinician. In the US, the USPSTF publishes updated recommendations for common screenings (e.g., diabetes, hypertension, statin use for primary prevention).[1][2][3]
¶ Retest Cadence (Rule of Thumb)
- Acute effects (days): sleep timing, caffeine timing, light exposure → track daily.
- Weeks: training blocks, stress interventions → track daily + weekly review.
- Months: body composition, lipids, HbA1c → retest on month-scale (or per clinician).
- Slow markers: epigenetic clocks → think many months to a year.
¶ Practical “Do/Don’t”
Do
- Track one primary outcome and 1–3 supporting metrics.
- Write a stopping rule before you start (e.g., adverse symptoms, BP threshold, abnormal labs).
- Keep a simple change log (date, intervention, dose/parameters, adherence).
Don’t
- Add a stack of 6 new things at once.
- Change diet, training, sleep, and supplements simultaneously if you’re trying to learn.
- Ignore symptoms or abnormal labs because “it’s probably fine.”
