I am 15 years old and 88 pounds is that normal for your age?

In my opinion that is underweight for your age. 88 pounds is not normal for 15. I would guess a normal 15 year old female would weigh around at least 120 and a male 130 to 140. a lot of girls your age try to loose weight on fad diets but end up gaining weight. Although i think your weight is underweight for your age you should always be happy with the way you look and most importantly dont let anyone else get jealous that you are skinny.
