Body mass index (BMI)
What is Body Mass Index (BMI)?
BMI is a measure of body fat based on a person's weight and height. It is calculated by dividing weight in kilograms by height in meters squared. A BMI between 18.5 and 24.9 is considered healthy, while a BMI over 30 is considered obese. BMI is a useful tool for assessing overall health, but it is not a perfect indicator and should be used in conjunction with other measures.
