Dilemma

My thirteen year old niece is bugging her mother on how to lose weight fast. She said her classmates and friends in school are always teasing her that she is fat and she wants to stop the teasing. Kids often times are harsh especially when they are bullying. My sister does not know what to do about it because she knows her kid is young and should not be worrying about her weight. On the other hand she wants her to loose weight as well because my niece will soon be in the category of obese. I think they are seeking the schools’ guidance councilors for the matter. I hope it will not make a big damage on my niece’s paradigm about herself.
