Marketing, Psychology, and the Mechanisms of Fast-Food Overconsumption: A Case Study of McDonald’s

Using McDonald's as a global case study, this research investigates the phenomena of overconsumption in the fast-food sector. It contends that excessive consumption is caused by a systemic interplay between behavioral psychology, marketing design, and socioeconomic factors rather than just human decision. McDonald's deliberately lowers consumers' cognitive work while boosting emotional satisfaction through food formulation, pricing, promotion, and spatial accessibility, resulting in compulsive overconsumption. In order to demonstrate how choice architecture, habit loops, and reward learning produce a feedback loop that reinforces repetitive eating behaviors, the study combines insights from behavioral economics, neurology, and marketing. Therefore, rather than being a sign of weakness on the part of the individual, overconsumption is portrayed as a structural result of market innovation and cultural normalization. In order to address this issue and realign corporate profits with public health and social responsibility, the study emphasizes the need for ethical marketing frameworks and regulatory measures, such as transparent labeling and bans on child-oriented advertising.
