Understanding BMI Categories

The Body Mass Index (BMI) is a widely used tool to assess if you are at a healthy body weight for a person of your height. The standard BMI categories are:

  • Underweight: BMI < 18.5
  • Normal weight: BMI between 18.5 and 24.9
  • Overweight: BMI between 25 and 29.9
  • Obese: BMI ≥ 30

Important Notes

BMI is a useful screening tool, but it does not diagnose body fatness or health. It has limitations because it does not account for muscle mass, bone density, overall body composition, and racial and sex differences.

For a more comprehensive health assessment, consult with a healthcare professional who can consider your individual circumstances and provide personalized advice.
