What is BMI?
BMI, or Body Mass Index, is a simple numerical value calculated from your height and weight. It is one of the most widely used screening tools to categorize whether a person is underweight, at a healthy weight, overweight, or obese. While it doesn't directly measure body fat, it provides a useful starting point for understanding your overall health.

Limitations of BMI
BMI is a useful general guide but it does have limitations. It does not account for muscle mass, bone density, age, or gender differences. For example, a very muscular athlete may have a high BMI but very low body fat. Always consult a healthcare professional for a complete health assessment.
