Izzie has always been 'curvy' but since Christmas, she has gained 8 pounds, and nothing seems to fit anymore! In an attempt to lose weight, Izzie tries everything: one diet after another, a punishing exercise programme and every bit of conflicting advice everyone can give her. Her constant worrying about her weight causes her to lose her 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 a cute boy at the TV studio who seems to appreciate her just the way she is.
