What Is BMI?

Body Mass Index (BMI) is a measure of body fat based on your weight relative to your height. It applies to adult men and women and is used as a screening tool for weight categories.

BMI Categories

  • Below 18.5 — Underweight
  • 18.5 – 24.9 — Normal weight
  • 25.0 – 29.9 — Overweight
  • 30.0 and above — Obese

Limitations

BMI does not directly measure body fat and doesn't account for muscle mass, bone density, or body composition. Athletes may have a high BMI despite being healthy.
