As adolescents are growing, eating becomes a big part of their lives. Some are eating a lot during growth spurts while others might be gaining weight, or teenage girls might think they are fat when that really isn't the case. I came across this article that I found helpful for young adults at this stage of life and hope you may benefit from them as well.

"Adolescents are not monsters. They are just people trying to learn how to make it among the adults in the world, who are probably not so sure themselves."
