Request #244

I am looking for a short story that believe appeared in READ magazine between 1977-1985.
The story involved a high school boy who was overweight and wanted to play the flute in the high school band to impress a girl.  He began to eat salads and jog to slim down. In the end she still rejected him but he did not turn back to eating a dozen jelly donuts. Sound familiar?

Solved by Lost Classics reader Sheesh, who writes: the story is called Fat Boy (real imaginative right?). I read it in a book of short stories called You Can’t Tell Me What To Do.
