According to the CDC, Body Mass Index (BMI) is a number calculated from a person's weight and height to determine the overall fitness of an individual. BMI does not measure body fat directly, but is used as a diagnostic tool to identify potential obesity problems.
Move the tab on the red bar to the number of your height, the tab on the yellow bar to your weight, or enter your height and weight in the corresponding boxes. Then click the green BMI box. Your BMI will be calculated automatically.
Below 18.5 = Underweight
18.5 - 24.9 = Normal
25.0 - 29.9 = Overweight
30.0 and above = Obese
The CDC cautions that people who are overweight or obese are at higher risk for chronic conditions such as high blood pressure, diabetes, and high cholesterol. Anyone who is overweight should try to avoid gaining additional weight. Additionally, if you are overweight with other risk factors (such as high LDL cholesterol, low HDL cholesterol, or high blood pressure), you should try to lose weight. Even a small weight loss (just 10% of your current weight) may help lower the risk of disease. Talk with your healthcare provider to determine appropriate ways to lose weight.
