# Attention Affecting Response Inhibition in Overweight Adults with Food Addiction

## TL;DR

This study explores how attention issues in overweight individuals with food addiction affect their ability to control responses, using brain activity measurements.

## Contribution

The study identifies a novel link between attentional deficits and response inhibition in food addiction through neurophysiological markers.

## Key findings

- Overweight individuals with food addiction showed attentional deficits indicated by abnormalities in microstate D and the P100 component.
- Microstate D and the P100 component significantly predicted No-Go performance, linking brain activity to behavioral inhibition.
- The findings suggest attention bias may be an important interaction factor in response inhibition among individuals with food addiction.

## Abstract

Food addiction is associated with attention bias and response inhibition deficits, while the relationship between these two domains is unclear. Participants with body mass index (BMI) ≥ 25 and exhibiting food addiction behaviors (FA group, n = 20) were compared with healthy controls (HC group, n = 23). We examined attention-inhibition mechanisms using resting EEG microstate analysis, food-cue-evoked event-related potentials (ERPs), and non-food Go/No-Go tasks. Overweight individuals with food addiction behaviors demonstrated attentional deficits, as indicated by abnormalities in microstate D and the P100 component. Importantly, both microstate D and the P100 component significantly predicted No-Go performance, linking neurophysiological markers to behavioral inhibition. This study suggests that attention bias may be an important interaction factor of response inhibition, providing novel mechanistic insights into food addiction.
