About BMI
Body Mass Index (BMI) is a simple measure using your height and weight to work out if your weight is healthy. The BMI calculation divides an adult's weight in kilograms by their height in metres squared.
Limitations
BMI is not used to definitively diagnose body fatness or health, but rather to screen for potential weight categories that may lead to health problems. Factors like muscle mass, age, gender, ethnicity, and body composition are not considered.
