Understanding BMI and Health

What is BMI?

Body Mass Index (BMI) is a screening tool used to determine if you are underweight, normal weight, overweight, or obese. It's calculated using your weight and height and provides a general indication of whether you have a healthy weight for your height.

How is BMI Calculated?

BMI = weight (kg) / height (m)². For imperial units: BMI = (weight in pounds × 703) / (height in inches)². This simple formula provides a standardized way to assess weight categories across different populations.

BMI Limitations

BMI doesn't distinguish between muscle and fat mass, so athletes or very muscular individuals may have high BMIs despite being healthy. It also doesn't account for fat distribution, age, or ethnicity differences in body composition.
