Do you really need to lose weight? The BMI Calculator below will figure out your body mass index category (underweight, normal weight, overweight, or obese). This body mass index calculator is based on the standard BMI measurement that takes your weight and height and basically tells you if you have an unhealthy body weight. It works for adults, both men and women above age 19. It is a good indicator of the amount of body fat you have, which is directly related to the risk of various diseases and early death.
Body Mass Index (BMI) is a heuristic measure of body fat based on height and weight that applies to both adult men and women. It does not represent an accurate percentage of body fat, and does not take into account the individual's bone density or muscle mass.
