Body Mass Index(BMI) can be used to indicate if you are overweight, obese, underweight or normal. It will, however, overestimate fatness in people who are muscular or athletic. It is not a good index for adolescents or children. Because of these problems with BMI, this calculator shows extra statistics to help inform and judge your paitent's body compared to others of the same height and age, including these weight and height charts.
Women tend to believe they look their best at values between 20 to 22 and men are usually satisfied with a BMI of 23 to 25. If BMI is between 17 to 22, life expectancy is longer than average.
