In the last few decades, the obesity rate has increased along with the increasing of away-from-home food consumption at restaurants (Wei & Miao, 2013), especially the food consumption at quick-service restaurants (QSRs). Previous research stated that the main factors that influence the customers’ food selection are found. Price and quality of food are the most significant things that mostly concerned customers when they are in decision-making process. There is a controversial argument between several studies that identified calorie labelling on menu influences consumers on food choice, while others said vice versa. However, several studies argued that calorie information does not have as much impact on customers’ food purchasing as other factors such as food’s quality, ranges of food, price of food, restaurant’s atmosphere, and speed of food service (Carey & Genevive, 1995). The aim of this chapter is to examine the importance of representing calorie information on menu and its effects on customer decision-making especially at QSRs. Therefore, the following questions have been addressed in this chapter:

What are the factors that influence consumer choice at QSRs?

Does calorie labelling on menus impact customer purchasing at QSRs?

This chapter starts with the introduction of the topic and reviewing previous research on menu labelling and calorie information at QSRs. This chapter aims to provide a better understanding of customer decision-making when ordering a food with regard to calorie information on the menu and the customer preference.

Nutritional disorders and unhealthy nutrition, which are recognised as the causes of many widespread health problems (overweight, obesity, diabetes, cardiovascular disease, cancer, etc.) have emerged as a significant problem that requires resolution. The purpose of this study is to influence dietary preferences and to reduce current health issues by using gamification as a social marketing tool. To this end, the decision-making processes affecting food choices in individuals based on calorific content were evaluated and the effectiveness of gamification in encouraging consumers to make lower-calorie choices was examined.

An experimental design was used to determine the effect of gamification on the dietary preferences of consumers. An independent factorial design (between groups) in which multiple variables were tested with different subjects was used to test the factors that were thought to affect the food choices made by the participants from gamified and non-gamified menus.

In Study 1, menus (gamified vs non-gamified) and nutritional consciousness (low vs high) had a significant main effect on the total calorie count of the selected foods. In Study 2, menus (gamified with prices vs non-gamified with prices) had a significant main effect on the total calorie count of the selected foods, while nutritional consciousness (low vs high) did not. A significant interaction was observed between menus and nutritional consciousness.

Gamification can be used as an important publicity tool for promoting public health using different influential factors such as price.

This study shows that people can change their food preferences positively through gamification. It shows further how people tend to evaluate the price of their food rather than the calorie count when making dietary preferences. Gamification can, therefore, be considered a promising social marketing tool for improving public health.

Personalized price promotion (PPP) is a marketing instrument that addresses the limitations of untargeted promotions by tailoring the offers to individual customers based on their purchase histories. Current evidence on PPP is limited to its immediate effects on buying behaviors at grocery stores and food companies' economic benefits. Moreover, little is known about the role of consumer characteristics in determining how effectively this promotional tool works. Hence, we aim to assess the effectiveness of PPP in promoting healthy fast food and which consumer-specific factors affect its performance.

The authors conduct a laboratory experiment to examine the effects of personalized and non-personalized coupons for lower-calorie fast food menus on food and calorie selection. The coupon personalization is based on participants' menu choices, calorie needs and deal proneness. The authors additionally investigate how post-intervention changes are influenced by consumers' estimation of their selected calories, and their attitudes toward nutrition.

Recipients of personalized incentives are more likely than participants in the control group to redeem the offered coupons, select more healthy items and reduce their selected calories. Such changes are less likely among participants underestimating the calorie content of their menu choices and perceiving higher barriers to healthy eating. Personalized coupons perform better even among subjects receiving lower discounting levels than the control treatment.

As the first to evaluate the effectiveness of PPP in encouraging healthy food choices, this study highlights the potential of this cutting-edge price intervention and provides valuable implications for future research.

This study investigated whether consumers have reasonable estimates of the calorie content of Americans' top 10 favorite foods, explored the effects of calorie disclosure on United States consumers' future consumption frequency of these food items, and examined the effects of health consciousness, food calorie knowledge, and attitudes toward menu labels on intention to use menu labels.

An online survey was developed, pilot tested, and distributed through Amazon Mechanical Turk (AMT). The overall model fit and hypotheses were tested using structural equation modeling (SEM).

The results from 1,005 completed surveys showed that the accuracy of calorie estimations varied across food items. Most consumers could not estimate the calories of steak, hamburgers, chocolate chip cookies, and vanilla ice cream within the acceptable range. Disclosure of calorie information did affect future consumption frequency of the food items. The SEM results showed that health consciousness, food calorie knowledge, and attitudes toward menu labels positively affected consumers' future intention to use menu labels.

This study points to a need to educate consumers about food calories and suggests plausible ways to encourage consumers' intention to use of menu labels.

While the monetary returns to education are well documented in the economics literature, the studies on non-monetary returns to education are scarce. The purpose of this study is to provide new insights into the non-market outcomes by exploring how education influences the food consumption choices of households and how these effects vary across different socio-economic groups using household-level calorie consumption data from Sri Lanka.

This study uses two waves of Household Income and Expenditure Surveys – 2006/2007 and 2016. The methods adopted in analysing the data were descriptive statistics and the OLS regression model.

The empirical results show that educated poor households pay less per calorie compared to non-educated poor households, highlighting the role of education in improving the ability to make better food choices and manage household budgets more economically.

This study informs policy-makers of the importance of education for formulating food and nutritional policies, which aim to raise the standard of living of resource-poor and vulnerable households in Sri Lanka as well as other developing countries with similar socio-economic conditions.

To the best of the authors' knowledge, this study is the first to explore the impact of education on the calorie consumption behaviour of people in the Sri Lankan context using nationwide household surveys.

Recent research has demonstrated that people are more likely to engage with fatty food content online. One way health advocates might facilitate engagement with healthier, calorie-light foods is to alter how people process food media. This research paper aims to investigate the moderating role of viewer mindset on consumer responses to digital food media.

Two experiments were conducted by manipulating the caloric density of food media content and/or one’s mindset before viewing.

Results show that the relationship between nutrition and engagement is moderated by consumer mindset, where activating a more calculative mindset before exposure can elevate social media engagement for calorie-light food media content.

These findings contribute to the domain of obesogenic digital environments and the role of nutrition in consuming food media. By examining how mindsets interact with affective evaluations, this work demonstrates that a default mindset based on instinct can be shifted and thus alter subsequent behavioral intentions.

This work provides insight into what can boost the visibility and engagement of healthy food content on social media. Marketers can help promote healthier food media by cueing consumers to think more deliberately before exposure.

This research builds on recent work by demonstrating how to boost engagement with healthy foods on social media by cueing a more thoughtful mindset.

This study aims to examine consumers’ preferences among four calorie-reducing approaches – resizing, reformulation, substitution and elimination – and to understand what motivates consumers to order low-calorie food using the theory of planned behavior (TPB) as a model.

A conceptual model was developed based on the TPB with an additional construct of food choice motives. A total of 467 responses were collected. Descriptive statistics, multiple regression and ANOVA were used in the data analysis.

Consumers have a clear preference for substitution and elimination. The pattern that ingredients with higher calories were modified at a higher priority indicated that consumers might improve food decisions based on calorie information.

Restaurants should allow substitution or elimination of certain ingredients from menu items. Including more low-calorie sides will cost restaurants less than changing the main dish. A menu item on an entrée form is more amenable to modification for decreased calorie content as consumers have high taste expectations for popular traditional foods (e.g. burgers and pizza).

This is the first study to investigate consumers’ preferences among the four popular calorie-reducing approaches. A novel “Build Your Own Meal” approach was used in the questionnaire to allow the participants to choose from more than 150 ingredients, which compensated for personal preferences, thus mitigating possible limitations associated with studies of this kind, and was a good indicator of the participants’ actual ordering behavior.

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.

In The Changing Body (Cambridge University Press and NBER, 2011), we presented a series of estimates showing the number of calories available for human consumption in England and Wales at various points in time between 1700 and 1909/1913. We now seek to correct an error in our original figures and to compare the corrected figures with those published by a range of other authors. We also include new estimates showing the calorific value of meat and grains imported from Ireland. Disagreements with other authors reflect differences over a number of issues, including the amount of land under cultivation, the extraction and wastage rates for cereals and pulses and the number of animals supplying meat and dairy products. We consider recent attempts to achieve a compromise between these estimates and challenge claims that there was a dramatic reduction in either food availability or the average height of birth cohorts in the late-eighteenth century.

This chapter examines whether the supply of food is large enough to feed an increasing world population for the 2012–2050 period. Special attention is given to the implications of bioenergy production on global and regional food security.

For this analysis, a global food security simulation model was developed to determine if the global and regional supply of food, in terms of calories, is large enough to meet the demand and also to estimate the impact on food prices.

This chapter found that the global supply of food in terms of calories is insufficient to satisfy food demand in 2050, with food shortages especially significant in Africa.

The estimated shortage of food may result in significant food-price inflation by 2050.
