About BMI

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.

BMI Categories

Underweight BMI < 18.5
Normal weight BMI 18.5 - 24.9
Overweight BMI 25 - 29.9
Obese BMI ≥ 30

Limitations

BMI may not be accurate for athletes (high muscle mass), pregnant women, or the elderly. It's a screening tool but not a diagnostic of body fatness or health.
