Background. In this meta-analysis we review the findings from neuropsychological studies on set-shifting in people with eating disorders (EDs) or overweight/obesity. Method. Four databases (PubMed, PsycINFO, PSYNDEX and Web of Science) were searched for eligible studies. Effect sizes (ESs) were pooled using random-effects models. Moderator analyses were conducted for ED and overweight/obese subgroups, adult/adolescent samples and measures of set-shifting. Results. Sixty-four studies with a… 
Central coherence and set-shifting between nonunderweight eating disorders and anorexia nervosa: A systematic review and meta-analysis.
TLDR
It is found that people with bulimia nervosa clearly have central coherence and set-shifting inefficiencies which do not significantly differ from those observed in people with anorexia nervosa.
Scrutinizing Domains of Executive Function in Binge Eating Disorder: A Systematic Review and Meta-Analysis
TLDR
Individuals with BED were found to show worse performance on working memory tasks compared to obese individuals without the disorder, and the findings did not provide definitive evidence of alterations in other aspects of executive functioning.
The set-shifting profiles of anorexia nervosa and autism spectrum disorder using the Wisconsin Card Sorting Test: a systematic review and meta-analysis
TLDR
While difficulties with set-shifting appear to be stable in ASD, there may be differences between children and adults with AN, which warrant further investigation.
Decision making, central coherence and set-shifting: a comparison between Binge Eating Disorder, Anorexia Nervosa and Healthy Controls
TLDR
Two different neurocognitive profiles emerged: a strong cognitive rigidity and a central coherence based on the details was predominant in patients with Anorexia Nervosa, while a lack of attention and difficulty in adapting to changes in a new situation seemed to better describe patients with BED.
Research Review: What we have learned about the causes of eating disorders - a synthesis of sociocultural, psychological, and biological research.
TLDR
Multiple biopsychosocial influences are implicated in eating disorders and/or disordered eating symptoms and several can now be considered established risk factors.
Contribution of executive functions to eating behaviours in obesity and eating disorders
TLDR
It is suggested that treatments for obesity and ED would benefit from addressing difficulties in cognitive functioning, in addition to the more evident clinical symptoms related to eating, body weight and shape.

TLDR
ToM deficits, particularly in ToM-PT, can be a specific feature of AN but not BN, and contribute to poor insight, treatment resistance, and social impairment in AN.
Disordered Eating Attitudes and Behavioral and Neuroelectric Indices of Cognitive Flexibility in Individuals with Overweight and Obesity
TLDR
The relationship between disordered eating attitudes and cognitive flexibility extends to individuals with overweight and obesity and is independent of age, sex, IQ, weight status, and diet quality.

Set-Shifting Among Adolescents With Bulimic Spectrum Eating Disorders
TLDR
Cognitive inflexibility may develop over time because of the eating disorder, although it is possible that there is a subset of individuals in whom early neurocognitive difficulty may result in a longer illness trajectory.

Objectives The aim of this study was to explore cognitive flexibility in a large dataset of people with Eating Disorders and Healthy Controls (HC) and to see how patient characteristics (body mass
Insight in eating disorders: clinical and cognitive correlates
TLDR
Insight in EDs seems to be partially dependent on intact mental flexibility, with patients with the restricting type of AN having poorer overall insight than Patients with the binge-purge type of the disorder (AN-B/P).
Latent structure of eating disorder symptoms: a factor analytic and taxometric investigation.
TLDR
The results of the taxometric analyses were inconsistent with a strictly dimensional model of eating disorders and suggested that some features may be dimensional whereas others may be taxonic (discrete).

TLDR
This large dataset supports previous smaller scale studies and a systematic review which indicate poor cognitive flexibility in people with ED.

TLDR
Over the last 10 years, the prevalence of obesity associated with disorders characterized by the presence of binge episodes, namely bulimic disorders, is increasing, and this is linked with greater clinical severity and a poorer prognosis.
