About BMI

Body Mass Index (BMI) is a numerical value calculated from your weight and height. It provides a simple way to categorize individuals as underweight, normal weight, overweight, or obese.

BMI Categories:

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

Note: BMI is a screening tool but not a diagnostic of body fatness or health. It doesn't account for muscle mass, bone density, or overall body composition.
