About BMI (Body Mass Index)
BMI is a measure of body fat based on height and weight. It's a useful screening tool to identify potential weight problems, but it doesn't directly measure body fat or account for factors like muscle mass, bone density, or overall body composition.
How BMI is Calculated
Metric Formula: BMI = weight(kg) ÷ height(m)²
Imperial Formula: BMI = (weight(lbs) ÷ height(in)²) × 703
Limitations of BMI
- Doesn't distinguish between muscle and fat mass
- May not be accurate for athletes with high muscle mass
- May not be suitable for elderly people or children
- Doesn't account for body fat distribution
- May not be accurate for certain ethnic groups
Important: BMI is a screening tool and should not be used as the sole indicator of health. Always consult with a healthcare provider for a comprehensive health assessment.
