BMI, or Body Mass Index, is a measure of body fat based on a person’s height and weight. It is calculated by dividing a person’s weight (in kilograms) by their height (in meters squared). This measurement is used to determine if a person is underweight, normal weight, overweight, or obese. While BMI is not a direct measure of body fat, it is a useful tool for assessing overall health and identifying potential health risks associated with weight. A BMI within the range of 18.5 to 24.9 is considered healthy, while a BMI above 25 is considered overweight and a BMI above 30 is considered obese. However, it is important to note that BMI is not always an accurate indicator of health, as it does not take into account factors such as muscle mass and body composition.
