About BMI
Body Mass Index (BMI) is a value derived from the mass and height of a person. It provides a simple numeric measure of a person's thickness or thinness.
BMI Categories:
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5 to 24.9
- Overweight: BMI 25 to 29.9
- Obese: BMI 30 or greater
Note: BMI is a screening tool but not a diagnostic of body fatness or health. Athletes may have a high BMI due to increased muscle mass rather than fat.

What is BMI?
BMI (Body Mass Index) is a simple calculation that uses your height and weight to estimate body fat. Developed by Adolphe Quetelet in 1832, it's now the standard medical screening tool for weight categories.
