Frequently Asked Questions

BMI (Body Mass Index) is calculated using the formula:

BMI = weight (kg) / [height (m)]²

For imperial measurements:
BMI = (weight (lbs) / [height (in)]²) × 703

While BMI is a useful screening tool:

• Doesn't differentiate between muscle and fat
• Doesn't account for body composition
• Should be used with other health indicators

Always consult a healthcare professional for health assessments.
