Understanding Your BMI

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is:

BMI = weight (kg) / [height (m)]2

It's a useful screening tool, but it doesn't diagnose the body fatness or health of an individual.

BMI Categories:

  • Underweight: BMI less than 18.5
  • Normal weight: BMI from 18.5 to 24.9
  • Overweight: BMI from 25 to 29.9
  • Obesity: BMI 30 or greater

Consult with a healthcare professional for a more accurate assessment of your health status.
