 Weight management and social media have played important roles in modern society, and are intimately linked to our physical and mental health. This study explored the relationship between problematic social media use and selective exposure during the weight management period and the effects on their emotional and body satisfaction. In this study, 240 valid samples were collected in total through the online questionnaire survey method. Additionally, this study found that over-browsing, over-interaction with influencers, anti-algorithm, and selective exposure can lead to both negative emotions and positive emotions for users. The result shows a strong inverse correlation between negative emotions and the level of body satisfaction with oneself.
