What is BMI?
Body Mass Index (BMI) is a simple screening measure that relates your weight to your height. It's a quick way to flag whether weight might be a health concern — it doesn't account for muscle mass, bone density, or body composition, so it's best used as a starting point rather than a diagnosis.
Formula
BMI = Weight (kg) ÷ Height (m)²
Categories (WHO standard): Underweight < 18.5 · Normal 18.5–24.9 · Overweight 25–29.9 · Obese ≥ 30.
