Metabolic biohacking is highly measurable — but also easy to overcomplicate. Pick one metric, stabilize sleep and movement, then adjust nutrition or timing.
- Primary: HbA1c (longer-term), fasting glucose (context-dependent), or CGM metrics if used.
- Secondary: sleep timing, steps/activity, meal timing.
- Optional: waist circumference (trend), resting HR.
Run a 2‑week “meal timing” experiment:
- Keep diet composition stable.
- Move the last meal earlier by 2–3 hours.
- Track sleep quality and next‑morning appetite/energy.
