Is 13 stone obese for a 14-year-old?

The answer is: it depends

13 stone (182 lbs) is generally considered to be obese for a 14-year-old. However, it is important to remember that body mass index (BMI) is just one measure of health, and it does not take into account things like muscle mass and bone density. Therefore, it is important to talk to a doctor before making any decisions about whether or not a 14-year-old is obese.
