BMI Calculator: Understanding Your Body Mass Index
Body Mass Index (BMI) is a crucial health metric calculated as:
Advanced BMI Considerations for Accurate Health Assessment
Athletes may show "overweight" BMI due to muscle density. Our Body Fat Percentage Calculator provides more accurate body composition analysis.
Asian populations may have higher health risks at lower BMI. Older adults may need slightly higher BMI (up to 27) for optimal health.
Metabolic Health Calculators
Our BMR (Basal Metabolic Rate) and TDEE (Total Daily Energy Expenditure) calculators use scientifically validated equations:
Mifflin-St Jeor Equation (Most Accurate):
Men: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
Women: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161
TDEE = BMR × Activity Factor
Body Fat Percentage: Key to Fitness Goals
Essential fat vs storage fat - our Navy Method calculator estimates body composition using:
Men: 86.010 × log10(abdomen - neck) - 70.041 × log10(height) + 36.76
Women: 163.205 × log10(waist + hip - neck) - 97.684 × log10(height) - 78.387
Note: All calculators use evidence-based formulas and are regularly updated according to latest medical research on nutrition and fitness.
