Body Mass Index (BMI) Calculator
The Body Mass Index (BMI) is a widely used screening tool that helps to categorize whether a person's weight is healthy in proportion to their height. While not a diagnostic tool, it can indicate potential weight-related health risks for the general population.
How to Use the Calculator:
Enter your weight in kilograms (kg) and your height in centimeters (cm) into the fields below. Click "Calculate BMI" to see your BMI score and its corresponding weight category.
Understanding Your BMI:
BMI is calculated using a simple formula: BMI = weight (kg) / (height (m))^2. The resulting number falls into one of several categories:
- Underweight: Less than 18.5
- Normal weight: 18.5 – 24.9
- Overweight: 25.0 – 29.9
- Obesity: 30.0 or greater
Important Considerations:
While BMI is a useful screening tool, it has limitations. It does not directly measure body fat or distinguish between muscle and fat. For example:
- Athletes and very muscular individuals may have a high BMI due to muscle mass, not excess fat, and might be classified as overweight or obese even if they are very lean.
- Elderly individuals may have a normal BMI but have lost muscle mass and gained fat, which isn't reflected.
- Different ethnic groups may have different healthy BMI ranges.
- Body composition (the proportion of fat to muscle) is a more accurate indicator of health than BMI alone.
Therefore, BMI should be used as a general guide. For a comprehensive assessment of your health and weight status, it's always best to consult with a healthcare professional who can consider other factors like waist circumference, body fat percentage, diet, physical activity levels, and family history.
