Why diet?

Why is the world so obsessed with diets? It seems every magizine I see has some fast way to tone your body or lose weight. These things are a joke. Most of the diets are unhealthy, and will not last. Almost every tv show I watch the women are obsessed with their figure. This causes the rest of the world to believe the same thing. People idealize the characters on tv, and some will do anything to look like them. This might include those silly diets that are everywhere. It is really sad and the world should change their image of themselves. We are all different, and where meant to be different.
