University students are a unique population with great potential to adopt eating habits that promote positive human and planetary health outcomes. The purpose of this study is to illustrate the current perceptions of sustainable eating behaviours among the students and to examine the determinants of sustainable eating behaviours.

Data were collected from December 2020 to May 2021 through focus group discussions among university students in Ontario, facilitated through synchronous online sessions. There were 21 student participants during the course of five focus group sessions (4–5 participants per session) from various departments within the university. The discussions were transcribed and analyzed for main themes and concepts using open coding; deductive coding based on the framework by Deliens et al. as well as the literature; and inductive coding for emerging themes.

The students had different perceptions about what constituted sustainable eating behaviours, some of which were not based on fact. A variety of individual, environmental (macro, micro and social) and university characteristics were mentioned as factors influencing sustainable food choices, with “food literacy” and “campus food” being the top two factors.

This study presents a novel and holistic overview of how sustainable eating behaviours and sustainable foods are perceived among university students and identifies the perceived determinants of adopting sustainable eating behaviours. This study helps with identifying opportunities to promote sustainable eating behaviours among university students and the design/implementation of informed interventions and policies aimed at improving eating behaviours.

As technology increasingly integrates into the restaurant industry, avatar servers present a promising avenue for promoting healthier dining habits. Grounded in the halo effect theory and social comparison theory, this study aims to delve into the influence of avatars' appearance, humor and persuasion on healthier choices and customer satisfaction.

This paper comprises three experimental studies. Study 1 manipulates avatar appearance (supermodel-looking vs normal-looking) to examine its effects on perceived attractiveness, warmth and relatability. These factors influence customer satisfaction and healthy food choices through the psychological mechanisms of social comparison and aspirational appeal. Studies 2 and 3 further refine this theoretical model by assessing the interplay of appearance with humor (presence vs absence) and persuasion (health-oriented vs beauty-oriented), respectively.

Results suggest that avatars resembling supermodels evoke stronger aspirational appeal and positive social comparison due to their attractiveness, thus bolstering healthier choices and customer satisfaction. Moreover, humor moderates the relationship between appearance and attractiveness, while persuasion moderates the effects of appearance on social comparison and aspirational appeal.

This research bridges the halo effect theory and social comparison theory, offering insights enriching the academic discourse on technology’s role in hospitality.

The findings provide actionable insights for managers, tech developers and health advocates.

Despite its significance, avatar design research in the hospitality sector has been overlooked. This study addresses this gap, offering a guideline for crafting attractive and persuasive avatars.

People often look to the opinions and actions of others to guide their food choices, especially when they are uncertain or unfamiliar with a particular food. This influence can be positive or negative depending on the context and can have an impact on food consumption and health outcomes.

The paper analysed data from 500 young adult consumers in China and employed a multi-study design to examine various aspects of social proof and herd behaviour in food choices. Experiment 1 examined the influence of testimonials from an influential person on buying decisions and eating behaviour. Experiment 2 explored whether herd behaviour drives food options. Experiment 3 assessed the influence of social proof on food choices. Chi-square tests of independence were conducted to examine the relationship between social proof and food choice, as well as herd behaviour and food decision-making. Several logit regression analyses were performed to identify the factors that drive consumers' susceptibility to social proof and herding.

The results indicated that the source of feedback, whether from an influential person or a family member, did not have a statistically significant effect on the likelihood of following the food guide recommendations. The preference for a healthier food option was stronger than following the herd. In contrast, social proof in the form of reviews and ratings influenced participants' choices. The paper highlights the usefulness for stakeholders and policymakers seeking to promote healthier eating habits.

The originality lies in its comprehensive approach, combining multiple experiments and analytical methods.

This research aims to elucidate why consumers decide to eat meals that seem to be higher in calories and salt, despite their goal being to consume fewer calories and sodium. Korean participants are to be used for this study. The present research further investigated the impacts of categorization and averaging bias in relation to the health halo phenomenon, specifically focusing on traditional food and textured vegetable protein (soy meat) burgers. Thus, the present research investigated how consumers' intentions contrasted with their consumption goals in food choice circumstances.

We partitioned the survey due to the COVID-19 epidemic. A single, well trained surveyor first surveyed customers at cafés in Seoul and six other Korean cities. We received 102 in-person survey replies. A total of 254 advanced degree or undergraduate students from two universities completed an online questionnaire. There are 356 responses. Two studies were conducted where participants were instructed to evaluate the perceived healthiness, calorie content, and sodium level of different food items. The specifics of each study are elucidated in the main body of the paper.

This study shows that Koreans categorize meals as virtue or vice depending on their perceived healthiness, validating the categorization effect. Furthermore, this research demonstrated that consumers' perceptions of the health benefits of traditional meals and soy meat burgers impact their categorization. Koreans also assessed the average of the vice and virtue and found vice-virtue combination meals healthier than the vice alone. This affects how calories and sodium are perceived. This study also shown that high virtue affects averaging bias more than weak virtue in meals with vice and virtue combo.

This study extended food categorization and averaging bias to non-US consumers and confirmed this contradictory meal choice is universal. Health halo also affects food health perception. The results of this study revealed that Koreans consider traditional food healthier than western junk food. Korean customers incorrectly assume soy meat burgers have fewer calories and sodium than regular burgers. Thus, this study explains Korean consumers' food health misconceptions related to paradoxical consumption.

The growing number of Muslim consumers pursuing a lifestyle of health and sustainability (LOHAS) under the conditions of the COVID-19 pandemic is interesting to assess; however, existing research focusing on this topic remains scarce. This study aims to address the research gaps and add to the body of knowledge from previous literature related to Islamic religiosity, environmental knowledge, LOHAS and Muslim customer well-being.

The sample used in this study is Muslim customers, including university students in a medical department and medical workers in Indonesia, using proportional random sampling methods with a total sample of 308 respondents.

The results demonstrate that Islamic religiosity positively and significantly impacts environmental knowledge, LOHAS and Muslim customer well-being. Similarly, environmental knowledge positively and significantly influences LOHAS, and subsequently, LOHAS fruitfully impacts Muslim customer well-being.

The results can assist managers of eco-friendly and healthy products or services and public policymakers in their effort to enhance LOHAS, particularly for Indonesian Muslim consumers to accomplish well-being considering their Islamic religiosity.

The results of this study help society protect a sustainable environment by increasing their environmental knowledge and LOHAS. Based on Islamic religion, society recognize how important environmental issues are to keep the environment safe in the future and build the culture of LOHAS to achieve their well-being.

This study contributes to the body of marketing literature for Muslim green consumer behaviour in particular and the LOHAS of the Muslim customer segment based on Islamic religiosity.

Adequate vegetable consumption is fundamental to a healthy balanced diet; however, global compliance with recommendations is poor which is particularly important for young adults as they form food consumption habits. There is a growing interest in the circular economy of hospitality and sustainability of current dietary patterns in light of climate change and an expanding global population. The food value chain needs to be considered both vertically and horizontally where the research and development (R&D) investment is optimised by being “joined up” and not fragmentary; in addition, consumer trade-offs of health vs for example sensory appeal are taken into consideration. The purpose of this study was to identify factors predicting acceptance of vegetable dishes by young adults and present a roadmap that can be used for dish development and healthful marketing.

This study used the health belief model (HBM) as framework to investigate key factors that encourage vegetable intake by young adults using an online questionnaire sample of 444 enrolled in undergraduate programs at universities in Brazil.

Structural modelling showed that vegetable consumption frequency was positively influenced by Health concerns, Naturalness and Self-efficacy (including cooking skills), whereas Sensory factors and Familiarity demonstrated a negative loading that might be related to unpleasantness.

Globally, there is a strong need to promote the consumption of vegetables as a public health policy priority but also to ameliorate barriers to action that could be facilitated by availability, dish development and healthful marketing in hospitality operations.

Background: The prevalence of obesity in English adults and children has reached critical levels. Obesity is determined by a wide range of factors including the environment and actions to reduce obesity prevalence requires a whole systems approach. The spatial planning system empowers local authorities to manage land use and development decisions to tackle obesogenic environments.

Methods: This research aimed to better understand what and how planning powers are being utilised by local authorities to help tackle population obesity. It reviewed literature on the six planning healthy weight environments themes. It identified what powers exist within the planning system to address these themes. It collated professionals’ perspectives on the barriers and opportunities through focus groups within local authorities and semi-structured interviews with national stakeholders.

Results: The research complements current research on the association between the environment and obesity outcomes, though methods employed by researchers in the literature were inconsistent. It identified three categories of planning powers available to both require and encourage those with responsibilities for and involvement in planning healthy weight environments. Through direct engagement with practitioners, it highlighted challenges in promoting healthy weight environments, including wider systems barriers such as conflicting policy priorities, lack of policy prescription and alignment at local levels, and impact from reduced professional and institutional capacity in local government.

Conclusions: The conclusions support a small but increasing body of research which suggests that policy makers need to ensure barriers are removed before planning powers can be effectively used to promote healthy weight environments as part of a whole systems approach. The research is timely with continuing policy and guidance focus on tackling obesity prevalence from national government departments and their agencies. This research was conducted as part of a Master of Research at Leeds Beckett University associated with a national whole-systems to obesity programme.

Obesity is a significant public health issue. With obesity increasing worldwide, risk factors for obesity need to be better understood and require careful examination. This study aims to examine mental health as a risk factor for obesity using longitudinal data from Australia.

The main identification strategy relies on the recent death of a close friend and a serious injury or illness to a family member as exogenous shocks to mental health.

The authors’ preferred estimates, which account for the endogeneity of mental health, suggest that mental health has a significant negative impact on obesity. This result proves to be robust to a suite of sensitivity checks. Further investigations reveal that poor mental health leads to increased smoking, which also has an effect on obesity.

The study’s findings provide a new perspective on how good mental health helps curb obesity.

Though prosocial attributes are linked to positive outcomes among justice-involved adolescents and are a mainstay of numerous interventions, few measures have been specifically designed to evaluate prosocial functioning within this population. Although multiple instruments measuring aspects of prosocial behavior exist, these instruments were not designed to measure prosocial behaviors among youth in juvenile justice settings. This study aims to provide a preliminary validation of a new measure of prosocial attributes (the Prosocial Status Inventory – PSI), which was designed to comprehensively evaluate in greater depth the prosocial functioning of urban, justice-involved youth.

Youth (n = 51) were recruited as part of a larger study and were participants in a community-based mentoring program in a large, urban county in the Southern USA. Youth completed the PSI at baseline prior to their participation in the community-based mentoring program. The authors obtained follow-up data on recidivism from the county juvenile justice department.

PSI scores were positively related to a lower rate of recidivism and a decrease in offending frequency over a 12-month follow-up period.

The current findings complement previous work, suggesting that prosocial attributes are measurable and related to important outcomes among justice-involved youth and support the utility of strengths-based treatment approaches. Moreover, it provides preliminary evidence of the utility of a new self-report measure to assess these traits within a juvenile justice population.

Financial satisfaction is a potential ambition of individuals' lives that requires well-strategized economic behaviors. The authors examine the impact of various factors on the financial behavior (FB) and financial satisfaction (FIS) of individuals in India's National Capital Region (NCR).

Through a literature review, a survey questionnaire was formulated using existing scales on FIS. For more in-depth insights, data are obtained from 427 respondents in the NCR region using self-administered questionnaires. This article used “partial least square structural equation modeling (PLS-SEM)” to inspect the hypothesized model of individuals' FIS.

According to the study results, financial attitude (FA), financial self-efficacy (FSE), financial knowledge (FK) and demographic characteristics (DC) significantly influence FB. Conversely, financial stress (FS) negatively impacts FB. It also highlights that FA, FSE, FK and FB all significantly impact FIS. Nevertheless, FS and DC insignificantly influence FIS.

To the best knowledge of the authors, this article is an initial attempt to offer a novel perspective of individuals' FB and FIS in India. It would help the government and stakeholders by providing various pioneering economic schemes and making policies that help increase individuals' FIS.
