The study aims to explore perceptions- from the perspective of dietitians in Oman- towards the Internet of Things (IoT) in promoting well-being and sustainable health management thereby promoting Sustainable Development Goal 3 (SDG3). The study is based on the assumption that dietitians’ positive attitudes enhance the adoption of IoT in the context of dietetics. Methodology: An exploratory descriptive-deductive philosophy underpins the study's research design. A structured qualitative case study approach was used for data collection, involving e-surveys and semi-structured interviews with 12 male and female dietitians working in healthcare institutions. The study includes seven open-ended questions aiming at underscoring viable quotes that delve into the transformative potential of IoT. A thematic analysis is applied to identify the key themes to understand attitudes to IoT technologies among the participants. Findings: The findings suggest that dietitians have positive attitudes toward the potential of IoT technologies as they enable self-management by empowering individuals with actionable insights. IoT's ability to provide personalized care and real-time feedback can offer a proactive approach to sustainable health. Social interconnectedness and scalability are perceived as vital potentials. The results also reveal the importance of addressing data security and privacy concerns. This study deepens our understanding of dietitians’ attitudes and highlights the potential of IoT technologies. Significance: The study provides insights into dietitians’ views and experiences, suggesting a clear positive trend towards IoT technologies within the dietetics context. Thus, realizing the potential of such technologies should be accompanied by a full support system at different levels to promote well-being and sustained health management.
