A salient feature of anorexia nervosa (AN) is the persistent and severe restriction of food, such that dietary intake is inadequate to maintain a healthy body weight. Experimental tasks and paradigms have used illness-relevant stimuli, namely food images, to study the eating-specific neurocognitive mechanisms that promote food avoidance. This systematic review, completed in accordance with PRISMA guidelines, identified and critically evaluated paradigms involving images of food that have been used to study AN. There were 50 eligible studies, published before March 10th 2018, identified from Medline and PsychINFO searches, and reference screening. Studies using food image-based paradigms were categorised into three methodologic approaches: neuropsychology, neurophysiology, and functional magnetic resonance imaging (fMRI). Paradigms were reviewed with a focus on how well they address phenomena central to AN. Across tasks, differences between individuals with AN and healthy peers have been identified, with the most consistent findings in the area of reward processing. Measuring task performance alongside actual eating behaviour, and using experimental manipulations to probe causality, may advance understanding of the mechanisms of illness in AN.

“…Thus, women might engage in double standards (DS), which are observable when two persons possess an attribute to the objectively same extent, but are evaluated as different (Foschi, ). The application of DS in ED might also occur in domains other than body evaluation, as suggested by a previous study about the estimation of weight gain: Women with AN estimated more weight gain when they were asked to imagine eating a snack themselves than when imagining how much weight gain the same snack would produce in people generally (Milos et al, ). However, it is not possible to distinguish to what extent the different weight gain estimations of women with AN were based on realistic facts due to the different daily caloric intake of women with and without AN and to what extent they were attributable to DS for weight gain.…”

Objective Women with eating disorders (ED) evaluate their own body more negatively than do women without ED. However, it is unclear whether this negative rating is due to objective bodily features or different standards for one's own body and others' bodies. Therefore, the purpose of this study was to examine whether women with ED apply double standards when rating bodies by disentangling the objective features of one's own body from the feelings of ownership. Method We presented n = 34 women with anorexia nervosa, n = 31 women with bulimia nervosa, and n = 114 healthy controls with pictures of thin, average‐weight, overweight, athletic, and hypermuscular bodies. Identity was manipulated by showing each body once with the participant's own face and once with the face of another woman. Participants were instructed to report their emotional state according to valence and arousal and to rate body attractiveness, body fat, and muscle mass. Results Women with anorexia nervosa and bulimia nervosa displayed greater self‐deprecating double standards in body fat rating than did women without ED, as quantified by the difference between the ratings of the same body with one's own versus another woman's face. Double standards reflected in valence, arousal and attractiveness ratings were significantly more pronounced in women with anorexia nervosa than in women without ED. Discussion The double standards found may be due to an activation of dysfunctional self‐related body schemata, which distort body evaluation depending on identity. Double standards related to body fat were characteristic for women with ED, but not for women without ED.

Effects of hunger on mood and affect reactivity to monetary reward in women with obesity – A pilot study

Worldwide, nearly 3 million people die every year because of being overweight or obese. Although obesity is a metabolic disease, behavioral aspects are important in its etiology. Hunger changes the rewarding potential of food in normal-weight controls. In obesity, impairments related to reward processing are present, but it is not clear whether these are due to mental disorders more common among this population. Therefore, in this pilot study, we aimed at investigating whether fasting influence mood reactivity to reward in people with obesity. Women with obesity (n = 11, all mentally healthy) and normal weight controls (n = 17) were compared on a computerized monetary reward task (the wheel of fortune), using self-reports of mood and affect (e.g., PANAS and mood evaluation during the task) as dependent variables. This task was done in 2 satiety conditions, during fasting and after eating. Partially, in line with our expectation of a reduced affect and mood reactivity to monetary reward in participants with obesity accentuated by fasting, our results indicated a significant within-group difference across time (before and after the task), with monetary gains significantly improving positive affect in healthy controls (p>0.001), but not in individuals with obesity (p = 0.32). There were no significant between-group differences in positive affect before (p = 0.328) and after (p = 0.70) the task. In addition, women with obesity, compared to controls, reported more negative affect in general (p < 0.05) and less mood reactivity during the task in response to risky gains (p < 0.001) than healthy controls. The latter was independent of the level of satiety. These preliminary results suggest an impairment in mood reactivity to monetary reward in women with obesity which is not connected to the fasting state. Increasing the reinforcing potential of rewards other than food in obesity may be one target of intervention in order to verify if that could reduce overeating.
