The term “BMI” stands for Body Mass Index. BMI is a numerical value derived from a person's weight and height, used as an indicator of body fat and overall health. It is calculated by dividing a person's weight in kilograms by the square of their height in meters. BMI categories are often used to assess whether an individual is underweight, normal weight, overweight, or obese. While BMI is a useful tool for population-level assessments, it does have limitations, such as not accounting for muscle mass or distribution of fat. Healthcare professionals often combine BMI with other health metrics for a comprehensive assessment.
