Body Mass Index (BMI) is a numerical value of your weight in relation to your height. It's a common tool used to categorize a person as underweight, normal weight, overweight, or obese.

While BMI is useful for identifying potential weight problems in adults, it doesn't diagnose body fatness or health. It's best used as a screening tool alongside other assessments by your healthcare provider.

BMI Calculation Formula:

For Metric System:

BMI = Weight (kg) / [Height (m)]²

For Imperial System:

BMI = [Weight (lb) / Height² (in)] × 703

Limitations of BMI:

  • Does not directly measure body fat
  • May overestimate body fat in athletes and muscular individuals
  • May underestimate body fat in older adults or those who have lost muscle mass
  • Doesn't account for differences in bone density, muscle mass, or ethnic variations
  • Not suitable for pregnant women, growing children, or the frail elderly
