Biological Maintenance

Energy baseline and sleep-window planning with conservative limits.

Public health tools here focus on formula-based energy and sleep planning with clear assumptions. Use them as planning context, not diagnosis, treatment, or emergency guidance.

Start here

  • Metabolic Floor — Your BMR and TDEE — the starting point for every other calorie target.
  • REM-Sync — Optimal bedtime or wake-time windows.

Featured tools

Metabolic Floor · BMR / TDEE

Calculate your Basal Metabolic Rate and Total Daily Energy Expenditure using Mifflin-St Jeor. Power-consumption view with cut / maintain / bulk zones.

REM-Sync · Sleep Cycles

Find the optimal bedtime or wake time based on 90-minute sleep cycles. Wake at the end of a cycle, not the middle.

Frequently asked questions

› How accurate is BMR vs resting metabolic rate? Comparison

Mifflin-St Jeor is ±10% vs indirect calorimetry for a healthy adult. Lab RMR testing narrows the band if precision matters.

› Do these tools diagnose health problems?

No. They estimate planning numbers from published formulas. Use a qualified clinician, lab result, or official emergency guidance when the stakes are medical.
