Frequently Asked Questions
BMI (Body Mass Index) is a value derived from a person's weight and height. It's calculated by dividing your weight in kilograms by the square of your height in meters. For imperial units, the formula is [weight (lb) / height (in)²] × 703. BMI is used as a screening tool to indicate whether a person has a healthy body weight for their height.
BMI is a useful screening tool, but it has limitations. It doesn't distinguish between weight from muscle and weight from fat, so very muscular individuals might have a high BMI without having excess fat. It also doesn't account for where fat is stored in the body, which can affect health risks. BMI should be used alongside other health assessments and not as the sole indicator of health.
According to standard BMI guidelines, a BMI between 18.5 and 24.9 is considered to be in the "normal" or healthy weight range. Below 18.5 is classified as underweight, 25.0 to 29.9 as overweight, and 30.0 and above as obese.
