Body Mass Index (BMI) is one of the most widely used health metrics, but many people don't fully understand what it means or how to interpret it correctly.

What is BMI?

BMI is a simple calculation that uses your height and weight to estimate body fat. It's calculated by dividing your weight in kilograms by your height in meters squared.

BMI Categories

The World Health Organization defines BMI categories as follows:
