Body Mass Index (BMI) is a measurement used to evaluate an individual's body weight relative to their height. It is calculated by dividing a person's weight in kilograms by the square of their height in meters. BMI serves as a screening tool to categorize individuals into groups such as underweight, normal weight, overweight, or obese. While it is not a direct measure of body fat, BMI can indicate potential health risks associated with weight, such as heart disease, diabetes, and high blood pressure. The ideal BMI rate typically falls within the range of 18.5 to 24.9, which is considered normal weight. However, it is important to recognize that BMI has limitations and may not accurately reflect body composition for individuals with high muscle mass or certain health conditions.
