What is BMI?

Body Mass Index (BMI) is a number calculated from a person’s weight and height. BMI provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems. BMI is not diagnostic of the body fatness or health of an individual. Talk to your healthcare provider about what your BMI means and if you are at a healthy weight.

18.5 – 24.9	Normal	Your weight is within the normal range for adults of your height. Maintaining a healthy weight is important because it may reduce the risk of chronic diseases associated with overweight and obesity.
