Frequently Asked Questions
What is BMI?
BMI (Body Mass Index) is a measure of body fat based on height and weight. It applies to adult men and women. BMI = weight (kg) / height (m) squared.
What is a healthy BMI?
A BMI between 18.5 and 24.9 is considered normal/healthy weight. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
Is BMI accurate?
BMI is a useful screening tool but has limitations. It does not distinguish between muscle and fat mass, so very muscular people may have a high BMI despite low body fat. For a complete health assessment, consult a healthcare professional.
