What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The BMI formula is weight in kilograms divided by height in meters squared (kg/m²). It provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.

BMI Categories

  • Underweight: BMI less than 18.5
  • Normal weight: BMI 18.5-24.9
  • Overweight: BMI 25-29.9
  • Obesity Class I: BMI 30-34.9
  • Obesity Class II: BMI 35-39.9
  • Obesity Class III: BMI 40 or greater

BMI Limitations

While BMI is a useful screening tool, it has limitations:

  • Doesn't distinguish between muscle and fat mass
  • May not be accurate for athletes with high muscle mass
  • Doesn't account for age, sex, or ethnicity differences
  • Not suitable for pregnant women or children

Maintaining Healthy Weight

To maintain a healthy weight:

  • Eat a balanced diet rich in fruits, vegetables, and whole grains
  • Engage in regular physical activity (150+ minutes per week)
  • Stay hydrated and get adequate sleep
  • Monitor your weight regularly but don't obsess over daily fluctuations
  • Consult healthcare providers for personalized advice

  • BMI Calculator is completely free and secure to use
