Understanding Your BMI Results

Body Mass Index (BMI) is a widely used screening tool that can indicate whether you may have a healthy or unhealthy weight. It's calculated using your height and weight to work out if your weight is healthy.

Important Considerations About BMI

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

  • Doesn't distinguish between weight from muscle and weight from fat
  • May overestimate body fat in athletes and muscular individuals
  • May underestimate body fat in older persons and those who have lost muscle
  • Doesn't account for different body types and ethnic variations
  • Not suitable for pregnant women
