“…A series of experiments conducted by Chen et al [ 26 , 40 ] showed a lack of generalization of training effects to untrained or novel food items when training was focused at the item level (e.g., similar food items appear on go and no-go trials). However, there has been evidence to suggest that food-specific inhibition training could be generalized to untrained stimuli when training is focused on a category level (e.g., healthy food = go; unhealthy food = no-go) [ 34 , 48 , 50 ]. Combining these studies, our meta-analysis showed that, although the effects of food-specific inhibition training on the evaluation of trained food ( g + = 0.291) were numerically larger than on the evaluation of generalized food ( g + = 0.130) or mixed food ( g + = 0.150), the differences were not statistically significant.…”

“…Fortunately, many of the studies considered in this meta-analysis used open-source statistics and shared their raw data on many websites, such as the Open Science Framework. Based on these shared data [ 14 , 34 , 48 , 49 , 50 , 51 , 52 , 53 ], we conducted a mini meta-analysis to calculate the “true” correlation, and the correlation was accordingly set at r = 0.78.…”

Theories have suggested that food-specific inhibition training could lead to food devaluation which, in turn, may help people to regulate their eating behavior. In this review, we have synthesized the current literature on this topic by conducting a meta-analysis of studies investigating the effects of food-specific inhibition training on food evaluation. We identified 24 studies—with 36 independent samples, 77 effect sizes, and 3032 participants—that met our inclusion criteria. Effect sizes were analyzed using the robust variance estimation in random effects meta-regression technique. The results indicate that food-specific inhibition training can lead to statistically significant reductions in food evaluation. More specifically, it was observed that the effects of training on participants’ food evaluation differed according to the type of evaluation; food-specific inhibition training significantly decreased participants’ explicit food evaluation, but not their implicit food evaluation. However, because most of the included studies focused on trained food items and short-term outcomes in normal-weight samples, more research is needed on the continuance of the training effects, as well as on the extent to which effects can be generalized to untrained food items or different populations (e.g., overweight or obese individuals).

“…Binge eating was triggered by food cues or cues that could become related to negative affect in the model over the course of BN and BED (Chami et al, 2020). Novel treatments that target the components of the maintenance mechanisms are in development (Treasure et al, 2022) and showed improvements in inhibitory control (Chami et al, 2020; Keeler et al, 2022). However, CBT targeting multifactorial processes in the model remains untested in patients with BN and BED.…”

Objective: We aimed to evaluate the feasibility, acceptability, and potential impact of a tele-guided digital-based intervention based on the addictive appetite model of recurrent binge eating.Method: Female college students with bulimia nervosa (BN) or binge-eating disorder (BED) (n = 22) received a 6-week guided intervention targeting addictive processes and emotion regulation. The feasibility of the intervention was evaluated, and the outcomes were assessed at baseline, the end of the intervention, and 1-month follow-up.Results: Of the participants, 86.4% (n = 19) completed the intervention. The self-help materials were viewed 6.03 ± 3.06 times per week, and the duration of using the self-help materials was 113.16 ± 160.19 min/week. The intervention group experienced a significant reduction with a moderate effect on binge eating at the end of the intervention (Hedges' g = 0.58), and the effects lasted through follow-up (Hedges' g = 0.82).Discussion: The results suggest that the digital intervention targeting a maintenance mechanism of recurrent binge eating was feasible and acceptable for patients with BN and BED, proving the potential for symptom improvement.

Evaluating dietary restriction as a maintaining factor in binge‐eating disorder

ObjectiveProminent theories of binge‐eating (BE) maintenance highlight dietary restriction as a key precipitant of BE episodes. Consequently, treatment approaches for eating disorders (including binge‐eating disorder; BED) seek to reduce dietary restriction in order to improve BE symptoms. The present study tested the hypothesis that dietary restriction promotes BE among 112 individuals with BED.MethodsParticipants completed a 7‐day ecological momentary assessment (EMA) protocol before and after completing 17 weeks of either Integrative Cognitive‐Affective Therapy or guided self‐help cognitive behavioral therapy. Analyses examined whether dietary restriction on 1 day of the baseline EMA protocol predicted risk for BE later that same day, and on the following day. Changes in dietary restriction over the course of treatment were also evaluated as a predictor of change in BE from pre‐treatment to post‐treatment. Baseline dietary restraint was examined as a moderator of the above associations.ResultsDietary restriction did not predict BE later the same day, and changes in restriction were not related to changes in BE across treatment, regardless of baseline dietary restraint levels. Restriction on 1 day did predict increased BE risk on the following day for individuals with higher levels of dietary restraint, but not those with lower levels.DiscussionThese findings challenge the assumption that dietary restriction maintains BE among all individuals with BED. Rather, results suggest that dietary restriction may be largely unrelated to BE maintenance in this population, and that reducing dietary restriction generally does not have the intended effect on BE frequency.
