Have a celebrity “I am bulimic” program, in which celebs who do or did practice starvation dieting go to schools and speak to the youth who idolize them, telling them about the suffering and dangers of these weight loss methods. Film these talks and have them played in thousands of schools in case they can’t go to them all in person. Have a website, literature that teachers give out to kids and provide to parents. The stars' pictures on the literature will ensure the likelyhood that they will keep it, hopefully show it to their parents, and take heed of the advice.
