Digital technologies such as fitness health applications provide scalable solutions for eating behavior disorders, which are becoming more and more common. Nevertheless, little is known about their use in Saudi Arabia. This study aims to address this gap by assessing the impact of dietary diaries on students' eating behaviors and moods. Methods: The design is a quasi-experimental approach. To assess improvements in eating behaviours before and after using the diary, quantitative data is gathered using the Eating Attitude Test (EAT - 40) and (Mood and Feelings Questionnaire - MFQ). Participants log in their meals, feelings, and behaviours over a period of 7 days. Open-ended questions were used to collect qualitative data in order to investigate participants' experiences, and difficulties. For quantitative results, statistical methods were used to analyze the data; for qualitative findings, content analysis was employed. Implications: The study has a number of significant ramifications. By assessing the ability of dietary diaries to effectively regulate eating behaviours, it contributes to the larger field of behavioural health and increases our understanding of digital health interventions. The results could guide the creation of therapies specifically designed to meet the nutritional requirements and emotional difficulties of college students. The study closes a significant vacuum in regional research on digital health tools in Saudi Arabia by concentrating on students at Effat University. It also lays the groundwork for upcoming longitudinal research and the broader use of digital health resourcesenThesis
