Body Mass Index (BMI)

Body Mass Index (BMI) is a widely used measure to assess an individual's body weight relative to their height. It provides a simple numerical value that helps categorize individuals into weight groups, such as underweight, normal weight, overweight, or obese. This classification can be useful for identifying potential health risks associated with weight.

The World Health Organization (WHO) provides the following standard BMI categories:
Underweight: BMI < 18.5
Normal weight: BMI 18.5–24.9
Overweight: BMI 25–29.9
Obesity: BMI ≥ 30
