Understanding BMI

What is BMI?

Body Mass Index (BMI) is a measure of body fat based on height and weight. It's calculated using the formula: BMI = weight (kg) / height (m)²

BMI Categories (WHO Standards)

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

BMI Limitations

BMI doesn't distinguish between muscle and fat mass. Athletes with high muscle mass may have a high BMI but low body fat. Always consult healthcare professionals for comprehensive health assessment.
