What does this research mean for the field?

Sustainable dietary behavior and food waste reduction are driven by the complex interaction of multiple value dimensions—such as responsibility, economic interest, and social relations—across identity, emotional, and cognitive pathways, rather than by any single necessary factor. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Identify key value drivers motivating users to reduce food waste and construct a behavioral model for sustainable eating.
Employ grounded theory to identify value drivers.
Use fuzzy-set qualitative comparative analysis (fsQCA) to examine multiple factors.
Propose design patterns based on findings.
Three value-driven pathways influence sustainable eating behavior: value identification, emotional engagement, and cognitive empowerment.
Six key factors drive these values: responsibility awareness, economic interest, enjoyment, social relations, knowledge demand, and honor motivation.
No single factor constitutes a necessary condition for sustainable dietary behavior.
