The Effect of Watching Mukbang on the Desire to Eat

Study Overview
=================
Brief Summary
-----------------
The current study is designed to find the effect of mukbang on dieters. Mukbang is an online eating broadcast where a host (Asian mukbangs generally feature a young and slim female host) consumes a large amount of food while chatting with audiences. Since some dieters watch mukbang to get satiation and control their appetites, the investigators proposed the hypothesis that mukbang could increase people's satiation level and decrease their desire to eat. To test this hypothesis, one randomized controlled study was conducted and female participants were randomly selected to watch either a mukbang or a non-food related video. Their desire to eat were reported and measured after the video.
