How much is a 15-year-old girl supposed to weigh?
To know if one’s weight is ideal, CDC recommends using a BMI calculator. The BMI, or body mass index, is an indicator of body fat, and the calculator results are used to screen for overweight and obese children 2 years old and above. The BMI calculator is not a diagnostic tool of obesity because additional assessments are necessary to confirm the condition, the CDC cautions.
