The results confirmed the presence of a relation between executive functions and overweight/obesity , although the directionality of this relation was not clear ; nor did any single executive function emerge as being more involved than others in this relation .
Despite this , there was evidence of a reciprocal influence between executive functions and overweight/obesity .
Conclusions : This systematic review underlines the presence of a relationship between executive functions and overweight/obesity .
Moreover , it seems to suggest a bidirectional trend in this relationship that could be the cause of the failure of interventions for weight reduction .
Background : The increasing incidence of people affected by overweight or obesity is a significant health problem .
The knowledge of the factors which influences the inappropriate eating behaviors causing excessive body fat is an essential goal for the research .
Overweight and obesity are significant risk factors for many health diseases , such as cardiovascular problems , diabetes .
Recently , many studies have focused on the relationship between body weight and cognitive processes .
Objectives : This systematic review is aim ed to investigate the existence and the nature of the relationship between excessive body weight ( overweight/obesity ) and executive functions , analyzing cross-sectional , and longitudinal studies in order to verify the evidence of a possible causality between these variables .
Determinants of weight loss maintenance: a systematic review.
BACKGROUND Discerning the determinants of weight loss maintenance is important in the planning of future interventions and policies regarding overweight and obesity . We have therefore systematic ally synthesized recent literature on determinants of weight loss maintenance for individuals with overweight and obesity . METHODS With the use of the Preferred Reporting Items for Systematic Review s and Meta-Analyses statement , prospect i ve studies were identified from search es in PubMed and PsycINFO from 2006 to 2016 . We included articles investigating adults with overweight and obesity undergoing weight loss without surgery or medication .  Included articles were scored on their method ological quality , and a best- evidence synthesis was applied to summarize the results . RESULTS Our search result ed in 8,222 articles of which 67 articles were selected . In total , 124 determinants were identified of which 5 were demographic , 59 were behavioural , 51 were psychological/cognitive and 9 were social and physical environmental determinants . We found consistent evidence that demographic determinants were not predictive of weight loss maintenance . Behavioural and cognitive determinants that promote a reduction in energy intake , an increase in energy expenditure and monitoring of this balance are predictive determinants . CONCLUSION This review identifies key determinants in weight loss maintenance . However , more research regarding cognitive and environmental determinants of weight loss maintenance is needed to advance our knowledge on determinants of weight loss maintenance
