“…Ten of these studies employed the concept of choice architecture (66,71,76–78,82,85,97,102,104) to make changes to serving lines (66,78,97), to vending machines (85), or to indicate healthful and unhealthful foods by using traffic lights-like labels (76,77). Incentives, both monetary and non-monetary, used alone or in combination with other behavioral economics concepts (99), were reported in 8 studies (65,75,90,95,98,100,105).…”

“…In term of findings with policy implications, the studies included in this review propose: the use of traffic-light labels as means to promote healthy food choices (76,77); the use of incentives in combination with education to decrease consumption and reduce waste (88); changes in serving lines as a means to influence choice of healthful foods (72,78,81,102); and making the healthier choice the easiest choice (97) and the unhealthy choice more difficult to get (70).…”

“…These interventions apply behavioural economic principles and require little to no extra effort than regular day-to-day behaviour from individuals as they often operate without people's awareness (Hollands et al, 2016;Marteau et al, 2012). Such interventions have strong potential to be effective in promoting behaviour change (Marteau et al, 2012;Sheeran, Gollwitzer, & Bargh, 2013), and are already being used for research in real world field studies (Hansen, Skov, Jespersen, Skov, & Schmidt, 2016;Rozin et al, 2011).…”

Obesity and overweight levels are rising nationally, despite recent governmental advertising campaigns being implemented to tackle the prevalence rise at a population level. Therefore, alternative approaches should be investigated in an effort to reduce obesity prevalence rises. One such approach modifies the external cues and the environment where decisions about food are made, and it is commonly known as Choice Architecture (CA). The proximity effect is a strategy within CA that could reduce overall calorie consumption by placing healthier foods at relatively closer distances compared to unhealthy foods. Amongst studies examining the proximity effect, only one so far has explored the simultaneous presentation of healthy and unhealthy foods, referred to as a competitive food environment. As unhealthy foods are often preferred over healthy foods, the current study aims to investigate whether food choice can be overridden by varying degrees of proximity effect and whether key factors such as visual salience, perceived effort, BMI, age, food preference, and executive function moderate this effect. A sample of 48 undergraduate students will participate in a laboratory experiment, believing they are taking part in a relaxation study. Participants will be simultaneously presented with two bowls of food: A healthier fruit selection and an unhealthier chocolate option, each varying according to proximity (either 20cm or 70cm). The participants will be asked to complete a questionnaire measuring multiple factors that may influence food consumption, such as perceived effort and hunger level. The primary outcome of the study is the amount of each food consumed (in grams) depending on relative proximity, with the secondary outcome exploring whether the effect of the latter is influenced by the key moderators. The proposed study explores the proximity effect in a competitive food environment, an area rarely explored in research but high in real-world applicability. If a greater amount of the most proximal food is consumed in each condition, regardless of food healthiness, the intervention can be scaled up to a novel field experiment to further evaluate the effectiveness of the proximity effect in reducing calorie intake.

“…The latter used a fake food buffet, 13 a Foodscape Laboratory 26 and an online shelf-display. 27 In the field studies, different settings were involved, including dining facilities or cafeterias in schools (11), cafeterias in hospitals (2) as well as restaurants, buffet lines at conferences (2; 28,29 ), a cafeteria at a workplace, 30 a university, 31 a train station, 32 corner stores 33 and a swimming pool. 34 Most studies used a within subjects pre-post interventions design (10), or a between subjects design with a control and treatment group (9), while a minority used both a between-and within subjects design (4).…”

BACKGROUND: Nudging refers to interventions that organize the choice architecture in order to alter people's behaviour in a predictable way without forbidding any options or significantly changing their economic incentives. As a strategy to encourage healthy behaviour, nudging can serve as a complement to health education. However, the empirical evidence regarding the effectiveness of nudging as a way to influence food choice remains contradictory. To address this issue, a systematic review and meta-analysis was conducted to test the effects of nudging to encourage people to select more fruit and vegetables. METHODS: A systematic literature search was performed on PubMed, Medline, PsycInfo, Cochrane library, Scopus and Google Scholar. After quality assessment, 20 articles (23 studies) were retained for narrative synthesis. Twelve articles (14 studies) contained enough information to calculate effect-sizes for meta-analysis using Comprehensive Meta-analysis software. RESULTS: The meta...
