What is BMI?
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in meters squared.
It's used as a screening tool to indicate whether a person is underweight, normal weight, overweight, or obese based on tissue mass (muscle, fat, and bone).
While BMI is useful for most people, it does have limitations:
- It may overestimate body fat in athletes and muscular individuals
- It may underestimate body fat in older persons and those who have lost muscle mass
- BMI doesn't account for differences in body composition, ethnicity, gender, and age
