⚠️ BMI is a guidance indicator: it does not distinguish muscle from fat and ignores age or build. It is not a medical diagnosis — consult a health professional.
Frequently asked questions
How is BMI calculated?
Weight in kilograms divided by height in meters squared. Example: 70 kg and 1.75 m → 70 ÷ (1.75 × 1.75) = 22.9.
What are the WHO BMI ranges?
Below 18.5: underweight; 18.5–24.9: normal; 25–29.9: overweight; 30 or above: obesity.
Does BMI work for athletes?
With caveats: muscle weighs more than fat, so a very muscular person can score "overweight" while being fit. It is a population guide, not an individual diagnosis.
