BMI Calculator

Calculate Your Body Mass

Body Mass Index or BMI is a calculation that indicates your weight status by measuring height for weight. BMI is used for adults over 20 years old and falls into one of the following categories: 

BMI Clinical Guidelines                       Weight Status Classification   
 Below 18.5  Underweight
 19.0 - 24.9  Normal
 25.0 - 29.9  Overweight
 30.0 - 34.9  Class I Obesity (Mild)
 35 - 39.9  Class II Obesity (Moderate)
 > 40  Class III Obesity (Extreme)

BMI is closely correlated with body fat. However, there are limitations to this measurement. It may overestimate body fat in athletes and those that have short stature with a muscular build.

If your BMI falls in the normal range, good for you! Keep practicing healthy nutritional habits along with physical activity to prevent weight gain – especially as you age.  If you are not happy with your BMI classification, call us at 678-781-3021.
