BMI (Body Mass Index) is a measure of body fat based on height and weight. It helps assess if a person is underweight, normal, overweight, or obese.
BMI is calculated as weight (kg) divided by height (m) squared:
BMI = weight / (height * height)
BMI = weight / (height * height)
According to WHO:
- Underweight: Below 18.5
- Normal weight: 18.5 – 24.9
- Overweight: 25 – 29.9
- Obese: 30 and above
- Underweight: Below 18.5
- Normal weight: 18.5 – 24.9
- Overweight: 25 – 29.9
- Obese: 30 and above
BMI itself is calculated the same for both sexes. However, body fat distribution differs, so interpretation may vary slightly.
