The primary objective is to identify and analyze the factors influencing consumers' choices between alternative and traditional proteins, as well as the moderating conditions that shape these preferences. To achieve this, three sequential studies were conducted to examine the differential effects of temporal landmarks, self-transcendence, and mindset abstraction on protein choice. A randomized mixed experimental design was employed, incorporating both between-subjects and within-subjects components. Findings indicate that consumers exhibit a higher propensity to select alternative proteins during morning hours. Moreover, self-transcendence was found to mediate the relationship between temporal landmarks and protein choices, while mindset abstraction moderated this association. This research uniquely integrates temporal psychology, self-transcendence, and construal level theory to explain dynamic sustainable protein choices under climate change. It introduces morning contexts as novel antecedents of self-transcendence, demonstrating that self-transcendence mediates the impact of temporal landmarks on alternative protein preferences, with this relationship being moderated by mindset abstraction. The theoretical contribution lies in linking micro-level temporal cues to macro-level environmental values, providing a unified framework to address the “when” (time), “why” (self-transcendence), and “for whom” (abstract thinkers) of sustainable choices. Also, this research extends existing knowledge of dynamic sustainable consumption patterns. Practical implications include actionable strategies for policymakers and marketers to design time-sensitive interventions, such as morning-targeted campaigns. These initiatives leverage self-transcendent mindsets and abstract thinking to systematically promote sustainable protein adoption, thereby advancing climate change mitigation efforts.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"210 ","pages":"Article 107974"},"PeriodicalIF":4.6,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699278","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}

However, the impact of FOP labels on actual purchase decisions appears to remain rather limited. As healthy grocery shopping is an effortful and difficult task, shoppers may benefit from additional support. Therefore, this study examines shopper acceptance of seven <em>nutritional decision aids</em> (NDAs), tools that support shoppers with the identification and purchases of healthier food alternatives. We designed seven NDAs based on established (online) decision aids such as filtering and sorting and incorporated nutritional information (<em>i.e.,</em> Nutri-Score) to support healthy purchase decisions. We argue that coercive pressures embedded in the design of NDAs increase shoppers’ perceived intrusiveness, which in turn decreases NDA acceptance. Results from Study 1 show that the NDAs systematically vary in their degree of coercive pressure exerted on shoppers to make healthier purchase decisions (NDA coerciveness). Study 2, a large study among heads of household (<em>n</em> = 1031), demonstrates that when NDAs exert a high degree of pressure to make a healthy purchase decision, NDA acceptance decreases. Additionally, study results show that NDA coerciveness increases perceived intrusiveness, which in turn decreases acceptance, explaining part of the underlying mechanism. Lastly, we find that the effect of NDA coerciveness on perceived intrusiveness is less (more) pronounced for shoppers with high (low) healthy eating interests. Overall, the results of this research yield novel insights for the development of effective health interventions in grocery stores that benefit shoppers as well as retailers.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"210 ","pages":"Article 107972"},"PeriodicalIF":4.6,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The names on these products, specifically the use of meat-like designations on non-animal products, remains a major point of contention. The aim of this study was to investigate whether meat-like vs. non-meat-like names are potentially confusing or even misleading. In this study, a categorisation task was used where participants classified products as animal-based or plant-based. Our results show that the presence of a meat-like name on a meat alternative label leads to significantly more mistakes when classifying a product as plant-vs. animal-based. The response latency was on average 116ms longer when classifying these products compared with the other categories. This indicates that a consumer is in doubt whether the product should be classified as plant- or animal-based, possibly explained by the activation of unconscious cognitive processing and interference due to stimulus-response compatibility. When participants were asked to give their opinion about meat alternative labelling, views divided into two camps: some strongly believe that using meat-like names is misleading, while others consider it fully acceptable and not misleading in any way. Assessing whether a meat-like name is misleading involves more than the name itself; it requires considering label details, retail placement, and advertising. Ensuring accurate and transparent meat alternative labels begins with a clear legal basis and policy guidelines based on scientific research.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"209 ","pages":"Article 107965"},"PeriodicalIF":4.6,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, no studies to date have investigated whether IWB and fear of weight gain act concurrently and independently of one another to impact ED symptoms, or whether they interact synergistically, causing compounding risk for ED symptoms. Therefore, the current study tested unique and moderating relationships among IWB, fear of weight gain, and ED symptoms in a higher ED risk population. This study was preregistered. Participants (<em>N</em> = 1233; 62.2 % women) completed one-time survey data. Eight ED symptoms were the main outcomes. Multiple linear regression models were conducted to assess main and interactive effects of IWB in the entire sample and in a subsample of individuals with probable EDs (<em>n</em> = 311). In the entire sample, there were no significant interactions, but in individuals with a probable ED, IWB moderated the relationship between fear of weight gain and cognitive restraint. There were also main effects of IWB on all ED symptoms, and main effects of fear of weight gain on seven symptoms. Results suggest that IWB may compound the impact of fear of weight gain on cognitive restraint among individuals with EDs. Both IWB and fear of weight gain had unique relationships with most or all outcomes, suggesting they are independent constructs.

Yet accumulating evidence challenges this view, including studies showing that willingness-to-pay (WTP) is higher for foods displayed as real objects versus images –a phenomenon known as the “real object advantage” in valuation. Here, we examined whether the “real object advantage” is modulated by accessibility to the stimuli, subjective food preference, or interactions between these factors. Participants placed monetary bids on snack foods displayed as real objects or computer images. Critically, on half of the trials, a transparent barrier was positioned between the participant and the stimulus. Linear mixed-effects modeling analysis revealed that, overall, WTP was ∼7 % higher for foods displayed as real objects versus images; however, this effect emerged only for foods of moderate (but not strong) preference strength. WTP was also higher when the stimuli appeared unoccluded versus behind the barrier, but this was equally so for real objects and images, suggesting that the barrier's effect on valuation was not related to stimulus actability. Our findings suggest that while eliminating perceived barriers to a good can bolster valuation regardless of display format, presenting real foods may nevertheless increase valuation and encourage healthy dietary choices.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"209 ","pages":"Article 107973"},"PeriodicalIF":4.6,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672873","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}

To address this gap, we investigated the extent to which having vegetarian close ties (family members and/or partners) was related to participants' likelihood of eating vegetarian. Data were derived from Lifelines, a large cohort study from the northern Netherlands (n = 60,639). Two assessments an average of 3.9 years apart were used. We studied the interaction of close ties' diet trajectories (either vegetarian or omnivore) at baseline and follow-up, and their relationship to participants' own diet trajectories at baseline and follow-up. Mixed multinomial logistic regression was used to account for clustering among families. Participants closely mirrored their close ties' diet trajectories. Having close ties who were vegetarians at baseline and follow-up was associated with the highest probability of the participants themselves also eating vegetarian at both assessments (Pr = 0.08, 95 % CI: 0.07–0.08). In contrast, participants with no vegetarian close ties at baseline and follow-up were the least likely to be vegetarians themselves at both assessments (Pr = 0.02, 95 % CI: 0.02–0.02). Partners particularly had a strong influence on participants’ diet trajectories compared to other family members. It appears that the closer the tie was, the more closely diet trajectories paralleled each another.

The item pool was reduced and four factors identified using exploratory graphical analysis. The structure of the final set of 40 items was evaluated using confirmatory factor analysis. Convergent validity of the negative over- and under-eating scales was established using measures of body image-focused eating disorder and ARFID symptoms, and exploratory data on the correlates of positive over- and under eating were reported.
