Many of the young people we've met on "I Used To Be Fat" have looked to food to provide them with much more than a full stomach. Sometimes they eat for comfort, other times it's to escape their everyday heartache. Next week we'll meet Kelly, a high school graduate that lost her father and has used food to deal with it ever since. Check out a sneak peek from the new episode below, where her mom says that she fills the void of losing her dad with unhealthy snacks. Kelly feels like a huge disappointment, so hopefully she'll find a way to reshape her self-confidence in addition to her figure.
