The absolutely brilliant anorexia / bulimia / eating disorders website F.E.A.S.T. has just set up a 'Hall of Fame page' comprising what its Forum contributors believe to be the most helpful posts over the past few years. (Scroll down the page to get to the list.)
Members of FEAST's Around the Dinner Table Forum (ATDT) come from all over the world. What we all have in common is that we are parents of teenagers with anorexia, bulimia or other eating disorders. We're all at different stages of recovery and the truly supportive aspect of this Forum is that many parents of RECOVERED eating disorder sufferers return time and time again to offer advice and talk about the drivers that helped their child recover from anorexia, bulimia, etc.
So please check out the Hall of Fame above. You might just find the answer to your current problem. For example, I found a link to an old post about boys with anorexia which is incredibly relevant to my own experience / situation. Because it's an old post, I might not have found it otherwise.
Brilliant. Keep up the excellent work, FEAST!
