The documentary Supersize Me, directed by Morgan Spurlock, follows Spurlock as he eats only McDonald's food for 30 days to investigate the health effects. The documentary uses a linear, chronological structure to tell the story of Spurlock's month-long fast food diet. It employs various camera shots, locations, sounds, editing techniques, archive footage, graphics, and propaganda-style imagery to convey its critical message about the impacts of overconsumption of fast food on health and obesity rates in America.
