Answer:
Actors do not need to be thin or in shape to sell the show. In most shows the actors are perfect, their bodies are perfect, their skin is gorgeous, and all the teenagers are jealous at how perfect they are, so they try to change themselves to be like the actors. They starve themselves, they do whatever they can to be like the perfect stars they see on TV. This show is really a huge breakthrough. now teens can see that, you don't have to have a perfect body, you don't have to be like the stars you see on TV... now they can just be themselves.
