Frequently asked questions
What is BMI?
Body mass index: weight in kilograms divided by height in metres squared. It is a screening figure, not a diagnosis.
Is BMI accurate for athletes?
Not very. Muscle weighs more than fat, so muscular people can score as overweight. Waist measurement and body-fat percentage are better guides in that case.
What are the ranges?
Under 18.5 is underweight, 18.5 to 24.9 is the healthy range, 25 to 29.9 is overweight and 30 or more is obese, per WHO guidance.
