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 metres squared.
BMI is a useful measure of overweight and obesity. It is calculated the same way for both adults and children but is interpreted differently for children.
BMI Limitations
BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat mass, so athletes may have a high BMI despite being healthy.
Other factors like age, sex, ethnicity, and muscle mass can influence the relationship between BMI and body fat. Consult a healthcare provider for a complete assessment.
