I am 14 and I feel that I should be a little fatter. How much should a 14 year old girl weigh? I am skinny. I eat a lot so I think I should be getting fat about now. The other night I ate 2 dinners (1 of them was a 3 course meal)! I haven't hurled since about 2 years so I am definitely not anorexic. I try to gain more without eating junk food but its not working! I have a few friends that weigh less then me, but... Help? What is a good weight for my age? What are ways to stay healthy? Currently I weigh 91 pounds. I know I have to gain. Please no really mean comments because I already know I need to get thicker.
