The movie was directed by Morgan Spurlock who was also the main character, the person who ate nothing else than McDonald's for a period of 30 days to see the way it affected his health and his well-being.
The documentary was inspired by a news story Morgan saw one day. Two adolescent girls who suffer from obesity sued McDonald's claiming that the food served at the restaurant the aggressive advertising campaign pushed by the restaurant and aimed at children, in particular, had a big influence on the obesity pandemic.
Before the documentary started, Morgan was someone who had a great interest in sports and eating as healthy as possible. He was and still is an advocate who tries to promote a healthy lifestyle and who harshly criticizes the fast-food industry in America. His personal ideas about these types of restaurants are clearly seen in the documentary as well and Morgan often links fast-food with obesity and even death.
Morgan's aim was not only to show the effects a bad diet can have on a person's physical health but also the way the food we eat affects our mental status as well. Thus, a big portion of the documentary is used to show how a bad diet can aggravate certain mental health issues and even cause them.
The director of the movie wanted to present the effects of a bad diet in an unrestricted manner. Because of this, the images used and the way the information is presented appears at times to be harsh and out of place. However, they drive home the main idea of the documentary and, as it was later proven, helped bring some changes in the way the consumer sees fast-food and the way in which fast-food companies advertise their products.
