Calculate your Body Mass Index (BMI)
According to the American Cancer Society, body mass index, or BMI, is a way to help you figure out if you are at a healthy weight for your height. BMI is a number based on your weight and height. In general, the higher the number, the more body fat a person has. BMI is often used as a screening tool to decide if your weight might be putting you at risk for health problems such as heart disease, diabetes, and cancer. BMI is used to broadly define different weight groups in adults 18 years or older. The same groups apply to both men and women.
