Food-Related Impulsivity in the Triangle of Obesity, Eating Behaviors and Diet

Abstract

One of the determinants of food intake, impulsivity may contribute to the development and maintenance of obesity by triggering uncontrolled and excessive eating. It is estimated that increased impulsivity makes it harder to resist foods high in sugar, salt and fat. Evidence has been increasing in recent years regarding the roles of different components of impulsivity in obesity and some eating behaviors (especially uncontrolled, emotional and restrictive eating). Unfortunately, animal and human experiments examining the effects of dietary interventions on impulsivity and cross-sectional studies examining the food choices and consumption habits of individuals with high impulsivity are limited. Considering the role of impulsivity in eating disorders is important to elucidate the development and onset of eating disorders, as impulsivity may be associated with some impaired eating behaviors and behaviors such as substance use and non-suicidal self-harm. Current research shows that the use of impulsivity-focused approaches (computer-assisted cognitive training, psychotherapy etc.) to modify impulsivity in people with binge eating episodes is promising. In addition, mindful and intuitive eating trainings that focuses on problematic eating behaviors and difficulties in controlling food intake, can use in the treatment of eating disorders and obesity for reducing the level of impulsivity. In these treatments, complementary therapy to reduce impulsivity in addition to the healthy diet approach should be considered. This article examines the role of impulsivity in obesity and eating behaviors, the results of current intervention studies on this subject, and treatment approaches targeting impulsivity.
