Abstract Disinhibited eating involves overconsumption and loss of control over food intake, underpins many health conditions, including obesity binge-eating related disorders. Stress has been implicated in the development maintenance disinhibited behaviours, but mechanisms underlying this relationship are unclear. In systematic review, we examined how impact stress on neurobiological substrates food-related reward sensitivity, interoception cognitive explains its role behaviours. We synthesised findings functional magnetic resonance imaging studies acute and/or chronic exposures participants with eating. A search existing literature conducted alignment PRISMA guidelines identified seven investigating neural impacts people Five used food-cue reactivity tasks, one study a social evaluation task, an instrumental learning task to probe reward, circuitry.

Binge-Eating Precursors in Children and Adolescents: Neurodevelopment, and the Potential Contribution of Ultra-Processed Foods

Nutrients, Journal Year: 2023, Volume and Issue: 15(13), P. 2994 - 2994

Published: June 30, 2023

Binge-eating disorder (BED) is a highly prevalent disorder. Subthreshold BED conditions (sBED) are even more frequent in youth, but their significance regarding etiology and long-term prognosis unclear. A better understanding of brain findings associated with sBED, the context critical periods for neurodevelopment, relevant to answer such questions. The present narrative review starts from knowledge development emotional self-regulation circuits supporting emotion-regulation eating behaviour. Next, neuroimaging studies sBED samples will be reviewed, brain-circuitry overlap examined. Deficits inhibition control systems observed precede, hyperactivity reward regions characterize, overlapping BED. imbalance between reward/inhibition systems, implication interoception/homeostatic processing should further Recent potential impact that high consumption ultra-processed foods paediatric may have on these sBED/BED-associated then discussed. There need identify, early on, those individuals at risk developing neurodevelopmental stages when there great possibility prevention. However, sBED/BED pediatric needed.

Binge eating, social media disorder and attachment in adolescence: Gender differences in the mediating role of alexithymia

European Review of Applied Psychology, Journal Year: 2024, Volume and Issue: 74(6), P. 100936 - 100936

There is a need for research investigating factors accounting binge eating (BE) and social media disorder (SMD) in adolescence. Despite studies suggesting the role of both attachment alexithymia these disorders, there has been no investigation into mediating pathways linking different types relationships to BE SMD. A total 423 Italian adolescents (32.2% males, Mage = 16.88) completed self-report questionnaires attachment, alexithymia, eating, levels. Hypotheses were tested with Structural Equation Modelling including multigroup analyses. Almost all variables showed each other. was explained by mother peers genders, but effect significant only among girls.
