More Information

The BMI as a measurement of health has significant limitations. For instance, it does not take into account genetic history or habits such as smoking and drinking. However, it is useful in connection with several other measurements to determine your risk for certain diseases including diabetes and heart disease. It is important to consult with a doctor before basing any nutritional decisions on the results of this calculator.

What is the BMI?

The BMI (Body Mass Index) was developed by a Belgium statistician by the name of Adolphe Quelet in the mid-19th-century. It is an internationally recognized measurement of weight status, though the table which relates the numeric value to the actual weight status varies in several countries. We use the categories established by the US Department of Health and Human Services.
