What is BMI and Why is it Important?
Body Mass Index (BMI) is a measure that uses your height and weight to work out if your weight is healthy. It is a widely used screening tool to identify potential weight-related health problems. While it has its limitations, it can be a useful starting point for understanding your overall health.
How to Use the BMI Calculator

- View Your Results: The calculator will instantly display your BMI, your weight status category, and your healthy weight range.
Limitations of BMI
It's important to remember that BMI is not a perfect measure of health. It does not distinguish between fat and muscle mass, which means that very muscular individuals (like athletes) may have a high BMI but be perfectly healthy. It also doesn't account for factors like bone density, body composition, and ethnic differences in body fat. Therefore, it should be used as a general guide and not as a definitive diagnostic tool.
