Body Mass Index (BMI) is a simple numerical measure that calculates an individual's body fat based on their weight and height. It is widely used as a screening tool to categorize individuals into weight status groups, such as underweight, normal weight, overweight, and obesity, which helps in assessing health risks and guiding interventions. BMI serves as a foundational metric in various health assessments, including evaluations of nutrition status and the planning of appropriate lifestyle modifications for health improvement.
