<![CDATA[Food waste in the culinary sector poses a challenge to sustainable tourism. The proliferation of social media has given rise to the phenomenon of Fear of Missing Out (FOMO), which encourages impulsive consumption, while the culinary experience, consisting of taste and food portion size, also shapes the intention to reduce food waste. This study aims to analyze the influence of FOMO, taste, and food portion size on the intention to reduce food waste, with sustainable consumption behavior as a mediating variable among culinary tourism consumers in Batam. Using an explanatory quantitative approach with a cross-sectional survey, data were collected from 300 active social media users and analyzed using Structural Equation Modeling (SEM). The results show that FOMO has a significant positive effect on the intention to reduce food waste, food portion size has a significant positive effect and is the strongest predictor, while taste does not have a significant effect. Sustainable consumption behavior is shown to partially mediate the influence of FOMO and taste in a negative direction, but it is not significant for the portion size path. These findings provide an empirical model of sustainable consumer behavior as well as strategic recommendations for culinary business actors and policymakers in designing effective and contextual food waste reduction strategies.]]>
