About BMI
Body Mass Index (BMI) is a measure of body fat based on height and weight. While useful as a general indicator, BMI doesn't account for muscle mass, bone density, or body composition.
BMI Formula:
- • BMI = weight (kg) / height² (m²)
- • BMI = (weight (lbs) / height² (in²)) × 703
Limitations:
- • Doesn't distinguish muscle from fat
- • May not apply to all ethnicities
- • Not suitable for pregnant women
- • Less accurate for elderly individuals
