Understanding BMI
Body Mass Index (BMI) is a simple measurement using your weight and height to work out if your weight is healthy. The BMI calculation divides an adult's weight in kilograms by their height in metres squared.
While BMI is a useful screening tool, it's important to note that it has limitations:
- • BMI may overestimate body fat in athletes and muscular individuals
- • BMI may underestimate body fat in older persons and those who have lost muscle
- • BMI doesn't distinguish between fat, muscle, and bone mass
- • BMI doesn't account for where fat is stored in the body
