BMI Info


Body Mass Index or BMI is a calculation tool for indicating weight status. It is a measure of weight for height. 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.

The BMI Formula: weight (lb) / [height (in)]2 x 703

If your BMI falls in the normal range, good for you! Keep practicing healthy nutritional habits along with physical activity to prevent weight gain as you age.
