BMI = weight in kg / height in meters²

Example: A person weighing 73 kg and 1.78 m tall would have a BMI of approximately 23.

Important Note

While BMI is a useful screening tool, it does not directly measure body fat and has limitations. Factors like muscle mass, bone density, age, and ethnicity can affect BMI accuracy.

Key Limitations:

  • 1.Muscle vs. Fat: Athletes with high muscle mass may have high BMI despite low body fat.
  • 2.Age Differences: Older adults may have more body fat at the same BMI compared to younger people.
  • 3.Gender Variations: Women typically have more body fat than men at equivalent BMI values.
  • 4.Ethnicity Factors: Different ethnic groups may have varying health risks at similar BMI levels.
