Understanding BMI

What is BMI?

Body Mass Index (BMI) is a measure of body fat based on your weight and height. It is calculated as weight (kg) divided by the square of height (m²) in metric units, or weight (lbs) times 703 divided by the square of height (inches) in imperial units.

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 higher

Limitations of BMI

BMI is a general indicator of health but does not account for muscle mass, bone density, or overall body composition. Athletes or individuals with high muscle mass may have a higher BMI without being unhealthy. Always consult a healthcare provider for a comprehensive health assessment.
