Frequently asked questions
What is a healthy BMI range?
For most adults, a BMI between 18.5 and 24.9 is considered healthy. BMI is a general indicator and doesn't account for muscle mass.
Is BMI accurate for everyone?
BMI is a rough screening tool. Athletes and very muscular people may read as overweight despite low body fat. Consult a professional for a full assessment.
