What does BMI stand for and what does it measure?

BMI stands for Body Mass Index, and it measures body fat based on an individual's height and weight. This index is a widely used tool because it provides a simple numerical measure that can help categorize individuals into different weight classifications, such as underweight, normal weight, overweight, and obesity. By using height and weight data, BMI allows healthcare providers to assess potential health risks associated with body weight.

The formula for calculating BMI is weight in kilograms divided by height in meters squared. This straightforward calculation helps to provide a quick screening tool that indicates whether a person has a healthy body weight in relation to their height, which is essential in evaluating overall health and potential disease risk.
