Frequently Asked Questions
What is a healthy BMI range?
A BMI between 18.5 and 24.9 is considered normal weight. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is classified as obese.
How is BMI calculated?
BMI = weight (kg) / height (m) squared. For imperial units, the formula is BMI = (weight in lbs × 703) / (height in inches squared).
Is BMI accurate?
BMI is a useful screening tool but has limitations. It does not distinguish between muscle and fat, so athletes may have a high BMI without excess body fat. Consult a healthcare provider for a complete assessment.
