BMI (BODY MASS INDEX)

Body Mass Index (BMI) Chart for Adults

Body Mass Index is a number calculated from a person’s weight and height. BMI is one way to tell whether you are at a healthy weight, overweight, or obese..

• A BMI of 18.5 to 24.9 is in the healthy range.
• A BMI of 25 to 29.9 is overweight.
• A BMI of 30 or greater is considered obese.

Because BMI does not show the difference between fat and muscle, it does not always accurately predict when weight could lead to health problems. For example, someone with a lot of muscle – such as a body builder – may have a BMI in the overweight or obese range, but still be healthy and have little risk of developing diabetes or having a heart attack.
