About BMI

Body Mass Index (BMI) is a value derived from a person's weight and height. It provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients.

BMI Formula

The mathematical formula to calculate BMI is:

BMI = weight(kg) / height²(m)

BMI Categories

BMI Range Category
Below 16.0 Severe Thinness
16.0 - 16.9 Moderate Thinness
17.0 - 18.4 Mild Thinness
18.5 - 24.9 Normal
25.0 - 29.9 Overweight
30.0 - 34.9 Obese Class I
35.0 - 39.9 Obese Class II

BMI has limitations as it doesn't account for factors like muscle mass, bone density, and overall body composition. Athletes may have a high BMI due to increased muscle mass rather than body fat.
