TRANSPARENCE ET MÉTHODOLOGIE DU PRODUIT
Chaque calculateur sur Real BMI repose directement sur des équations mathématiques publiées, des données de référence de santé publique et des algorithmes transparents.
Real BMI est une application web indépendante créée et maintenue par Bhawanshi Dosi. Chaque outil de ce site est documenté ci-dessous avec sa formule exacte, son autorité de source, ses paramètres et ses limites.
Tous les calculs utilisent la littérature scientifique évaluée par des pairs et des équations publiées (Mifflin-St Jeor, Boer, Devine, US Navy).
Les résultats sont évalués par rapport aux repères officiels de l'Organisation Mondiale de la Santé (OMS) et du CDC.
Les données sont calculées instantanément dans votre navigateur via JavaScript — aucune donnée de santé n'est stockée en ligne.
Chaque calculateur précise clairement ce qu'il mesure et ce qu'il ne mesure pas, sans prétention clinique abusive.

Metric: kg / m² | Imperial: (lbs / inches²) × 703
WHO Technical Report Series 854 / CDC Adult BMI Standard
Height, Weight
Body Mass Index score & WHO Category
Measures total mass relative to height; does not distinguish muscle mass from adipose fat tissue.
kg / m² with WHO Western Pacific Ethnic Thresholds
WHO Western Pacific Region & IOTF Consultation (2000)
Height, Weight, Asian Ethnic Ancestry
Regional Asian BMI Classification (Cutoff at 23.0 kg/m²)
Applies to Asian populations due to higher visceral fat ratio at lower BMI levels; screening tool only.
Mifflin-St Jeor: 10W + 6.25H - 5A + S (+5 male / -161 female)
American Journal of Clinical Nutrition (Mifflin MD et al., 1990)
Age, Sex, Height, Weight
Resting Energy Expenditure (kcal/day)
Estimates resting metabolic rate; does not account for thyroid variance or extreme muscle mass variations.
BMR × Activity Multiplier (1.2 to 1.9 PAL Factors)
FAO/WHO/UNU Human Energy Requirements Expert Consultation
BMR, Physical Activity Level (PAL)
Total Daily Energy Expenditure (kcal/day)
Relies on self-reported activity categories; actual daily thermogenesis fluctuates based on NEAT.
Devine / Hamwi / Miller / Robinson Heights Equations
Standard Clinical Pharmacotherapy Formulas (Devine BJ, 1974)
Height, Sex
Reference Weight Bracket (kg / lbs)
Provides historical clinical dosing baselines; does not represent individual body composition targets.
US Navy Logarithmic Circumference Equations
Naval Health Research Center (Hodgdon & Beckett, 1984)
Height, Neck, Waist, Hip (women)
Estimated Body Fat Percentage (%) & Category
Estimates body volume based on circumference; less precise than DEXA or hydrostatic weighing.
Boer Equation (Men: 0.407W + 0.267H - 19.2 | Women: 0.252W + 0.473H - 48.3)
Boer P. (1984) Estimated Lean Body Mass Equations
Height, Weight, Sex
Estimated Fat-Free Mass (kg / lbs)
Mathematical approximation based on total mass and height; does not measure organ vs muscle breakdown.
Energy Difference Scenarios = TDEE - Selected Deficit
NIH / NIDDK Guidelines & Energy Balance Models
BMR, TDEE, Example Energy Difference
Daily Calorie Reference Baseline (kcal/day)
Mathematical energy differential model for planning reference; not a prescriptive medical weight loss plan.
Body Weight (kg) × Activity Multiplier (0.8g/kg RDA to 2.2g/kg ISSN)
International Society of Sports Nutrition (ISSN Position Stand)
Body Weight, Activity Level, Fitness Focus
Daily Protein Intake Reference Range (grams/day)
Provides educational reference ranges based on activity benchmarks; renal health considerations apply.
Acceptable Macronutrient Distribution Ranges (AMDR)
Institute of Medicine (IOM) Dietary Reference Intakes
Daily Calorie Intake, Goal Macro Split
Carbohydrate, Protein, Fat Distribution (grams)
General nutritional planning framework; individual dietary needs vary based on metabolic conditions.
