"Super Size" refers to a marketing strategy used by fast-food restaurants, particularly popularized by McDonald's. It involves offering customers the option to increase the size of their meal for a small additional cost. This typically includes larger portions of fries and drinks, encouraging consumers to consume more food. The concept gained significant attention with the release of the documentary Super Size Me in 2004, where filmmaker Morgan Spurlock documented his health decline after eating only McDonald's for 30 days. The film sparked discussions about fast food, portion sizes, and their impact on public health.
