Frequently Asked Questions
What is BMI?
BMI (Body Mass Index) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in metres squared.
What is a healthy BMI?
A BMI of 18.5 to 24.9 is considered a 'healthy weight'. Below 18.5 is underweight, 25 to 29.9 is overweight, and 30 or above is considered obese.
Is BMI accurate for everyone?
BMI is a useful screening tool but it has limitations. It doesn't account for muscle mass, bone density, overall body composition, and racial and sex differences.
