Everything you need to know

Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults.

BMI Categories:

  • Underweight: BMI is less than 18.5
  • Normal weight: BMI is 18.5 to 24.9
  • Overweight: BMI is 25 to 29.9
  • Obese: BMI is 30 or more

Note: BMI is a screening tool, but it does not diagnose the body fatness or health of an individual.
