However, its cognitive processing remains poorly understood. From a healthcare perspective, the current study adopts a dual-processing theory framework and employs the food time discount rate as a measurement paradigm to systematically examine the relationship between health behaviors and health intertemporal decision-making, as well as their underlying cognitive processing.</div></div><div><h3>Methods</h3><div>The current study consists of three interconnected sub-studies. Study 1 recruited 397 participants from northwestern and southwestern China, who were asked to rate 21 health behaviors across three dimensions: required effort, duration, and health impact. Cluster analysis was then used to test whether health behaviors could serve as proxy indicators of health intertemporal decision-making. Study 2 recruited 156 participants from northwestern China and explored whether health intertemporal decision-making simultaneously relies on heuristic and analytical processing by manipulating emotional tasks (heuristic processing) and working memory tasks (analytical processing). Study 3 recruited 30 participants from northwestern China and employed event-related potential (ERP) technology to compare intuitive preferences in health intertemporal decision-making under manipulations of time intervals.</div></div><div><h3>Results</h3><div>The results of Study 1 indicate that, compared to short-term-effortless health behaviors, long-term-effortful health behaviors scored significantly higher on effort investment (<em>t</em> = 22.902∗∗∗) and duration (<em>t</em> = 16.607∗∗∗), but significantly lower on health impact (<em>t</em> = −18.779∗∗∗), suggesting that health behaviors can be categorized into two types: long-term-effortful health behaviors corresponding to delayed large benefits and short-term-effortless health behaviors corresponding to immediate small benefits. This provides a feasible method for indirectly measuring health intertemporal decision-making through health behaviors.

We tested a brief meat reduction intervention in a preregistered experiment with a demographically representative sample of 1070 UK meat-eaters (2 × 2 between-subjects design). The intervention had two components: a reflection prompt encouraging participants to consider how their meat consumption might conflict with environmental concerns, and an action plan prompt offering practical suggestions for reducing meat consumption. The action plan prompt backfired, decreasing willingness to reduce meat consumption and increasing psychological reactance. The reflection prompt also increased reactance. Additional analyses revealed that antisocial tendencies - traits such as low empathy and a lack of concern for the morality of one's actions - were associated with lower willingness to reduce meat consumption, reduced support for plant-based food policies, and greater reactance. These traits also amplified the backfire effects of the intervention, further decreasing willingness and policy support among participants higher in antisocial tendencies.

From minor 'tweaks' to using convenience foods, our participants employed various strategies to maintain 'proper' meal routines, an everyday practice idealised across the sample. Female participants were particularly adept at revising food routines; however, there was a fragility apparent in this orientation to practice. Their narratives about declining foodwork contained moralised references to laziness and carelessness. Male participants, in contrast, did not express such ambivalence. For recent widows, losing a partner significantly disrupted their gendered domestic habitus, in turn challenging their identities configured through care-orientated foodwork. Our analysis reveals that food remains a key site for identity negotiation in later older age, a relationship structured by habitus. Attending to the heightened awareness generated during the inevitable biographical disruptions of later older age, especially disruptions related to loss, highlights the durability of the gendered domestic habitus. Supporting ageing in place must move beyond dominant nutrition-focused understandings of food and instead recognise that food dispositions are informed by sociocultural frameworks.</p>","PeriodicalId":242,"journal":{"name":"Appetite","volume":" ","pages":"108349"},"PeriodicalIF":3.8,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145311899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
