Calculatorist Health Editorial Team
Health Calculator Reviewers
The Health Editorial Team maintains 7 health/fitness calculators and 1 pregnancy calculator. The team's reviewers cross-check every formula against the originating clinical study or guideline — Mifflin-St Jeor (1990) for BMR, US Navy circumference method for body fat percentage, WHO BMI cut-offs with the South Asian-specific tighter range note, Naegele's rule for due date estimation. Every calculator's disclaimer explicitly states it is a screening or planning tool, not a diagnostic instrument or medical advice. The team treats calculator outputs as starting points for conversations with qualified physicians, dietitians, or gynaecologists.
Areas of expertise
- Body composition: BMI (WHO + South Asian cut-offs), body fat % (US Navy method)
- Energy needs: BMR via Mifflin-St Jeor, TDEE with activity multipliers, macros split
- Ideal weight ranges: Devine, Hamwi, Robinson formulas
- Pregnancy: Naegele's rule (LMP + 280 days), conception dating, ovulation window
- Hydration: weight-based water intake estimation
Editorial standards
- Formulas sourced from peer-reviewed publications (Mifflin-St Jeor 1990 in Am J Clin Nutr, etc.)
- Indian-specific clinical adjustments (e.g., South Asian BMI threshold) cited explicitly
- Disclaimers state clearly: calculators are screening tools, not diagnostic
- Pregnancy and fertility calculators emphasise that ultrasound dating is more accurate than LMP-based estimates

Review cadence
Annual review against current WHO/ICMR guidelines. Updates when major clinical guidelines change (rare; typically every 3-5 years).
