Frequently Asked Questions
What is a healthy BMI range?
A BMI between 18.5 and 24.9 is generally considered normal weight. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is classified as obese.
How is BMI calculated?
BMI is calculated by dividing your weight in kilograms by the square of your height in meters: BMI = weight(kg) / height(m)^2.
Is BMI accurate for everyone?
BMI is a useful screening tool but has limitations. It does not account for muscle mass, bone density, age, or sex. Athletes may have a high BMI but low body fat.
