Plain English summary Our understanding of the prevalence and impact of eating disorders has improved significantly over the past 20-years. Research highlights that rates of eating disorders are increasing. To inform the development of the Eating Disorder Research and Translation Strategy 2021–2031 this review aimed to better understand the global...

Excess consumption of unhealthy foods has become a major public health problem. Although one potential contributor to unhealthy consumption is poor inhibitory control, findings have been inconsistent. A meta-analysis of 35 studies was conducted to determine whether, and under which conditions, inhibitory control, as measured by the Go/No-Go and Sto...

Background: Risk factors represent a range of complex variables associated with the onset, development, and course of eating disorders. Understanding these risk factors is vital for the refinement of aetiological models, which may inform the development of targeted, evidence-based prevention, early intervention, and treatment programs. This Rapid...

Background Delayed diagnosis, gaps in services and subsequent delays in specialist care and treatment lead to poorer health outcomes for individuals with eating disorders (EDs) and drive significant government healthcare expenditure. Given the significant disease burden associated with EDs, it is imperative that current implementation research is s...

The aim of the present study was to examine the effect of verbal size descriptors on portion size selections. Specifically, we investigated a range of size options within an online ordering setting. A sample of 216 female Flinders University students were asked to select a side dish, drink, and dessert from one of three online menus with varying po...

Abstract Background Research has shown that body dissatisfaction is higher during the postpartum period compared to other periods of life, and strongly associated with disordered eating behaviours, which can lead to adverse health outcomes. While results from cross-sectional studies suggest that social media may play an important role in body dissa...

Instagram-based priming (e.g., subtly incorporating healthy drinks into the background of Instagram images) could potentially nudge healthier consumption behaviours. Given the negative health consequences associated with sugar-sweetened-beverage consumption, two experiments tested the effect of three sets of Instagram-based primes for nudging drink...

Background: Eating disorders (EDs) are potentially severe, complex, and life-threatening illnesses. The mortality rate of EDs is significantly elevated compared to other psychiatric conditions, primarily due to medical complications and suicide. The current rapid review aimed to summarise the literature and identify gaps in knowledge relating to a...

Cravings for a range of substances including drugs, alcohol, and food have been shown to predict subsequent consumption or use. However, this link has not yet been systematically examined for beverages other than alcohol. The present study aimed to provide a comprehensive investigation of cravings for non-alcoholic beverages and their link to consu...

Background Limited screening practices, minimal eating disorder training in the healthcare professions, and barriers related to help-seeking contribute to persistent low rates of eating disorder detection, significant unmet treatment need, and appreciable associated disease burden. The current review sought to broadly summarise the literature and i...

Social media have become a major part of contemporary life. They are also a potent source of idealized and unrealistic imagery. Contributing to the lack of realism is the ability to digitally modify photos by applying a filter or editing software. One strategy suggested to counteract the negative consequences of idealized imagery on body image is t...

The prevalence of unhealthy food cues in our environment is a major contributor to poor dietary behaviours. Emerging research has shown that changing the food environment through the co-presentation of a healthy food cue may subtly ‘nudge’ individuals towards making healthier choices. The present study aimed to investigate the effect of a healthy f...

Background Eating disorders (EDs) are highly complex mental illnesses associated with significant medical complications. There are currently knowledge gaps in research relating to the epidemiology, aetiology, treatment, burden, and outcomes of eating disorders. To clearly identify and begin addressing the major deficits in the scientific, medical,...

Soft drink consumption has become a major public health issue. The present study aimed to examine the role of rash impulsivity and reward sensitivity in soft drink consumption using the two-factor model of impulsivity. Participants were a community sample of 229 adults (19–77 years). They completed self-report measures of impulsivity (SUPPS–P), rew...

This review presents recent trends in social media and body image research, with a particular focus on different social media platforms, features unique to social media and potentially positive content for body image. First, it was found that visual platforms (e.g., Instagram) were more dysfunctional for body image than more textual platforms (e.g....

Although attentional bias modification has been shown effective in several appetitive domains, results have been mixed. A major contributor seems to be the choice of control condition. The aim of the present study was to compare attentional bias modification for chocolate against a new control condition, sham-n (neutral or no-contingency) training....

Previous attempts to promote healthy eating using explicit techniques have not been consistently successful. We therefore investigated an implicit strategy (item placement techniques) to encourage healthy food choices in the context of snack menus. Two experimental studies compared presentation of healthy items in the top, middle, and bottom sectio...

Global consumption of soft drinks has increased rapidly over the past 50 years, making this a major public health problem. Guided by dual-process models, the present study aimed to provide a comprehensive investigation of the roles of cognitive biases (evaluative, attentional, and approach biases) and self-regulatory control in soft drink consumpti...

In the age of social media, “likes” are increasingly considered a numerical indicator of popularity and a measure of self-worth. Using an online questionnaire, Australian women (N = 291) aged 18–55 years self-reported their reaction to Instagram removing the visibility of the number of likes from other people’s posts, and completed measures of comp...

Continual exposure to soft drink cues in the environment is thought to be a major contributor to the rising consumption of soft drinks. This study investigated the effect of one such cue, television advertising, on soft drink choice and intake. Within the context of dual-process models, we examined whether any such effects would be stronger for ind...

Celebrities are well-known individuals who receive extensive public and media attention. There is an increasing body of research on the effect of celebrities on body dissatisfaction and disordered eating. Yet, there has been no synthesis of the research findings. A systematic search for research articles on celebrities and body image or eating diso...

One recent trend on Instagram consists of posting ‘Instagram vs reality’ images containing side-by-side photographs of the same woman, one an idealized depiction and the other a more natural depiction. This study aimed to experimentally investigate the effect of such images on body image. Participants were 305 women aged 18–30 years who were random...

Despite men using social media in increasing numbers, as yet there has been little research addressing effects on men’s body image.

The aim of the present study was to separate out dispositional and behavioral attributions by both manipulation and measurement and thereby to investigat...

One increasing trend on social media is the posting of body positive content that aims to challenge narrow beauty ideals and instead promote acceptance and appreciation of all bodies. The aim of the present study was to experimentally investigate the effect of body positive captions attached to Instagram images on young women’s body image. Particip...

Social media have given rise to new forms of self-presentation, in particular, the posting of self-portrait photos, commonly known as “selfies.” The aim of the present study was to experimentally investigate the relationship between selfie editing and body dissatisfaction. Participants were 130 women aged 18–30 years who were asked to view Instagra...

Research has shown that exposure to Instagram images is harmful for women’s body image. Although Instagram consists of photos of both peers and celebrities, the top followed Instagram accounts are held by thin and attractive female celebrities. The present study aimed to experimentally investigate whether two forms of Instagram caption could mitiga...

One increasing trend on social media is the posting of challenging or “reality check” comments about idealized photos of thin and attractive women. The aim of the present study was to experimentally investigate the effect of viewing such reality check comments after a positive appearance comment on young women’s body image. Participants were 192 wo...

The present study experimentally examined the effects of viewing Instagram images of fitspiration on body dissatisfaction, mood, and exercise behaviour among young women. Further, the study investigated if exercise engagement following exposure to fitspiration images could mitigate any negative effects from image exposure. Participants were 108 wom...

Idealised imagery depicting the functionality of a model's body (e.g., in fitness contexts) can trigger negative effects in viewers similar to, or worse than, traditionally posed images of models. Thus far, most of this research has been conducted on images of thin models. Building upon previous research, we examined the effect of pose (active vers...

Energy drink consumption is increasing worldwide, especially among young adults, and has been associated with physical and mental health problems. In two experiments, we tested the prediction that energy drink consumption is in part driven by biased cognitive processing (attentional and approach biases), with a view to modifying these to reduce con...

Instagram is a popular social networking site where users can post and share photos. One increasing trend on the site is the posting of natural and unaltered images. The present study aimed to experimentally investigate the effect of enhancement-free (i.e., no makeup, no digital alteration) Instagram images and their accompanying hashtags on women'...

Participants were 260 female undergraduate students whose eye movements were recorded while viewi...

The present study aimed to investigate whether the provision of prior information about digital alteration would enhance the effectiveness of disclaimer labels attached to fashion images in protecting against body dissatisfaction. Participants were 363 female undergraduate students who viewed fashion magazine advertisements with either no label or...

The present study aimed to investigate the effect of the spatial positioning of a healthy food cue in the context of unhealthy food cues on subsequent food choice. Undergraduate women (N = 143) were asked to choose a food from a pictorial-style menu that presented a salad and three unhealthier food options in a horizontal line. The position of the...

The Compensatory Health Beliefs Model proposes that individuals may believe that an unhealthy behaviour can be compensated for by subsequent engagement in a healthy behaviour. The present study aimed to test this proposition, specifically by examining the influence of snack consumption (healthy, unhealthy) on type of activity selected (physical, se...

The aim of the study was to investigate maternal feeding strategies as prospective predictors of young children's food preferences. Participants were 106 mother – child dyads with data collected when children were aged 4 (Time 1) and then again at 6 years old (Time 2). Mothers completed an initial questionnaire at Time 1 which contained measures of...

The contemporary food-rich environment has been consistently linked to unhealthy eating. Emerging research suggests that changing the presentation context of unhealthy foods by introducing a subtle nudge in the form of a healthy food cue may promote healthier dietary choices. This study investigated the effect of the timing of a healthy food cue (b...

Positive body image is a multidimensional construct referring to love, respect, and acceptance of one’s body, including aspects inconsistent with sociocultural ideals. The aim of the present study was to investigate potential pathways leading from religion and spirituality to positive body image. Participants were 345 women who completed questionna...

The Elaborated-Intrusion Theory of Desire (Kavanagh, Andrade, & May, 2005) suggests that cravings are made up of two distinct stages whereby an initial, seemingly spontaneous craving-related thought is sufficiently intrusive and pleasant for it then to be elaborated with vivid mental imagery. Previous questionnaire studies have investigated the cra...

"Selfies" (self-taken photos) are a common self-presentation strategy on social media. This study experimentally tested whether taking and posting selfies, with and without photo-retouching, elicits changes to mood and body image among young women. Female undergraduate students (N = 110) were randomly assigned to one of three experimental condition...

Instagram is an increasingly popular social networking site where users post and share photos.

The present study aimed to investigate experimentally the effect of number of likes accompanying Instagram images on women's own body dissatisfaction. Participants were 220 female undergraduate students who were randomly assigned to...

Restrictive feeding strategies have been associated with increased eating in the absence of hunger in a small number of studies of young girls. The aim of the present study was to examine a broader range of maternal feeding styles and eating in the absence of hunger in both girls and boys aged 3-5 years old. Participants were 184 mother-child dyads...

The present study experimentally examined the impact of different forms of inspirational fitness images (“fitspiration”) on women’s body image. Australian female participants (n = 152, 17–30 years-old; Mage = 21.55, SD = 3.94) were randomly assigned to view fitspiration media which depicted the body in a functional (performing exercise) or non-func...

The present study investigated the effect of two craving reduction techniques, namely, cognitive defusion and guided imagery, on naturalistic food cravings. These techniques targeted the intrusion and elaboration stages of the craving process, respectively (Kavanagh, Andrade, & May, 2005). Participants underwent a seven-day baseline period followed...

Thinspiration and fitspiration represent contemporary online trends designed to inspire viewers towards the thin ideal or towards health and fitness respectively.

The experiment investigated the impact on women's body dissatisfaction of different forms of label added to fashion magazine advertisements. Participants were 340 female undergraduate students who viewed 15 fashion advertisements containing a thin and attractive model. They were randomly allocated to one of five label conditions: no label, generic...

Although it is well-established that an objectively deserved misfortune promotes schadenfreude about the misfortune, there is a small body of research suggesting that an undeserved misfortune can also enhance schadenfreude. The aim of the present study was to investigate the processes that underlie schadenfreude about an undeserved misfortune. Part...

We tested the effectiveness of a positive appearance or functionality reflective writing task on women's body satisfaction and whether these writing task reflections offered any protective advantage when exposed to idealised imagery. Young adult women (N=230; Mage=23years) wrote about positive elements of either their appearance or their body's fun...

Recent studies have documented a shift in the cultural ideal of physical attractiveness, with women subscribing to a visibly toned ideal that emphasises health and fitness. The present study experimentally investigated the impact of athletic and muscular fitness-idealised images compared to traditional thin ideal images on women’s body dissatisfact...

Two experiments investigated whether attentional bias modification can inoculate people to withstand exposure to real-world appetitive food cues, namely television advertisements for chocolate products. Using a modified dot probe task, undergraduate women were trained to direct their attention toward (attend) or away from (avoid) chocolate pictures...
