Izzie has always been 'curvy', but since Christmas, she has gained eight pounds, and nothing seems to fit any more! In an attempt to lose weight, Izzie tries everything - one diet after another, a punishing exercise programme and every bit of conflicting advice anyone can give her. Her constant worrying about her weight causes her to lose confidence, and she stops appreciating the things in her life that are special - her supportive friends, the fact that she has been selected for a TV teen panel and the cute boy in the studio who seems to appreciate her just the way she is.
