This study aims to evaluate the effectiveness of an artificial intelligence (AI)-supported, context-aware digital nudging intervention designed to reduce ultra-processed food consumption and improve dietary sustainability among adolescents and young adults. The intervention utilizes real-time behavioral data, including image-assisted dietary logging and contextual information, to identify high-risk consumption moments and deliver personalized, non-coercive nudges. The study will assess changes in ultra-processed food intake, contextual consumption patterns, and sustainability-related dietary indicators.

Change in ultra-processed food consumption (servings per day)
Change in ultra-processed food consumption, expressed as servings per day, assessed using dietary intake data collected via a digital dietary assessment platform (food diary-based tracking system). Consumption will be quantified based on reported frequency and portion size.
From baseline to 10 months and 20 months
Change in frequency of ultra-processed food consumption (times per day)
From baseline to 10 months and 20 months
Change in proportion of ultra-processed food consumption (% of total intake)
From baseline to 10 months and 20 months
Participants receive an artificial intelligence (AI)-supported, context-aware digital nudging intervention designed to reduce ultra-processed food (UPF) consumption. The system uses real-time dietary and contextual data to deliver personalized behavioural prompts.
Participants have access to the digital platform without active nudging components. No personalized behavioural prompts are delivered.
A context-aware digital intervention delivering personalized nudges based on real-time dietary behavior and contextual data to reduce ultra-processed food consumption.
