What is BMI?

Body Mass Index (BMI) is a numerical value derived from an individual's weight and height, serving as a simple method to categorize weight status and estimate body fat. It is a widely used screening tool that helps to identify potential weight-related health issues in adults and children. While BMI does not directly measure body fat, it provides a quick and easy assessment that can highlight weight categories associated with increased health risks such as underweight, normal weight, overweight, and obesity.

The Formula Behind BMI

The Body Mass Index is calculated using the following formula:

BMI = weight (kg) / height (m)^2

For those using imperial units, the formula is:

BMI = (weight (lbs) / height (in)^2) x 703

This formula provides a single number that can be interpreted using standard categories to assess whether an individual's weight is within a healthy range.

Why is BMI Important?

BMI is important because it offers a quick estimate of an individual's body fat levels. While it doesn't measure fat directly, it correlates with direct measures of body fat and serves as a simple, inexpensive, and non-invasive screening tool for categorizing weight status. Health professionals use BMI to identify individuals who may be at risk for health problems related to excessive weight or obesity, including diabetes, heart disease, and certain types of cancer.
