All About Body Mass Index
Body Mass Index (BMI) is a simple, widely used metric to estimate whether your weight matches your height. The formula was introduced by Belgian statistician Adolphe Quetelet in the 19th century.
BMI is calculated by dividing weight in kilograms by height in meters squared. Example: 70 kg and 175 cm → 70 ÷ 1.75² = 22.9.
The WHO classification: under 18.5 — underweight; 18.5–24.9 — normal; 25–29.9 — overweight; 30+ — obesity.

A BMI of 18.5 to 24.9 is considered normal. Below 18.5 indicates underweight; 25–29.9 indicates overweight; 30+ indicates obesity.
BMI is an approximate indicator. It does not account for muscle/fat ratio, age, or sex. For a precise assessment, consult a healthcare professional.
