What is BMI?

BMI (Body Mass Index) is a simple calculation based on weight and height. It is commonly used as a general screening measure, but it does not directly measure body fat and should not be used as a medical diagnosis.

BMI Categories

  • Under 18.5 — Underweight
  • 18.5 to 24.9 — Normal weight
  • 25 to 29.9 — Overweight
  • 30 or above — Obesity

BMI categories are general reference ranges and may not apply equally to every person.
