Internet technology has facilitated the use of a wide variety of different activities and applications in online contexts. Despite a large amount of research regarding these activities including online social networking, online gaming, online shopping, online sex, and online gambling, very little is known regarding online eating shows called 'mukbang' (i.e. a portmanteau of the South Korean words for 'eating' ['meokneun'] and 'broadcast' ['bangsong'] that refers to online broadcasts where individuals eat food and interact with the viewers). The present study carried out a scoping review of the academic and non-academic literature (i.e. peer-reviewed publications, academic theses, and the print media) in order to examine the psychological characteristics of mukbang viewers and consequences of mukbang watching. A total of 11 academic outputs from different disciplinary fields (mainly peer-reviewed papers) and 20 articles from national UK newspapers were identified following an extensive literature search. Results from the scoping review indicated that viewers use mukbang watching for social reasons, sexual reasons, entertainment, eating reasons, and/or as an escapist compensatory strategy. Furthermore, mukbang watching appears to have both beneficial consequences (e.g., diminishing feelings of loneliness and social isolation, constructing a virtual social community,) and non-beneficial consequences (e.g., altering food preferences, eating habits, and table manners, promoting disordered eating, potential excess, and 'addiction'). Implications of the study and directions for future research are also discussed.
