Frequently asked questions
What is a healthy BMI?
18.5–24.9 is the healthy range for adults. Under 18.5 is underweight, 25–29.9 is overweight, 30+ is obese. BMI is a screening tool, not a diagnosis.
How is BMI calculated?
BMI = weight (kg) ÷ height (m)². In imperial: BMI = (weight lbs ÷ height inches²) × 703.
Is BMI accurate for athletes?
BMI doesn't distinguish between muscle and fat, so athletes may have a high BMI despite low body fat. Use body fat % or waist circumference for a fuller picture.
