<![CDATA[The digital era has transformed dietary behaviors among Generation Z, contributing to the triple burden of malnutrition. This study explored the experiences of health students at the Faculty of Public Health, State Islamic University of North Sumatra, focusing on the relationship between social media exposure, eating patterns, and self-efficacy. A qualitative phenomenological approach was applied with ten participants. Data were obtained through in-depth interviews, observations, and 3x24-hour food recalls, then analyzed using Miles and Huberman’s framework. Findings revealed that seven participants consumed excessive calories, averaging 2,102 kcal/day, above recommended levels. Social media food content, particularly simulacra and mukbang, triggered increased appetite and grazing patterns, with frequent snacking episodes accounting for more than half of daily intake. Low self-efficacy in portion control further reinforced overeating behaviors, even among students with adequate nutrition knowledge. These patterns illustrate overnutrition within the broader triple burden of malnutrition. Social media creates a hyperreality that shapes consumption beyond biological needs, complicating nutritional challenges in the digital age. Strengthening digital literacy and enhancing self-efficacy are essential strategies to mitigate the risks of overeating and address the triple burden among Generation Z.]]>
