Objective: Emotional eating has been associated with high emotional reactivity, suppression of negative emotions and inhibitory control difficulties. The current study aimed to address the association of these factors and their combined effect on emotional eating. Method: Twenty-eight participants conducted an emotional Go/Nogo task including pictures of neutral, negative and positive scenes and an additional emotion suppression condition. Electroencephalographic (EEG) activity was recorded continuously. Emotional eating and habitual emotion suppression were assessed through questionnaires. Emotional reactivity to affective pictures was measured through a visual analogue scale and the amplitude of the electrophysiological late positive potential (LPP). Inhibition parameters were assessed behaviorally (i.e., commission errors) and through event-related potentials of the EEG (i.e., N2/P3-amplitudes). Results: The trait questionnaire data revealed that emotional eating was not correlated with habitual emotion suppression. During the emotional Go/Nogo paradigm, higher emotional eating scores were positively related to higher LPP amplitudes in response to negative affective scenes. Inhibitory control capacities were not related to emotional eating while watching neutral or negative pictures, but higher emotional eating scores were associated with more commission errors when negative emotions were suppressed. Discussion: Emotional eating tendencies seem to be related to higher reactivity when confronted with negative affective information and inhibitory control deficits may arise especially when an effort is made to suppress these negative emotions. Therefore, a focus on adaptive emotion regulation in treatments of emotional eating seems to be important; solely targeting inhibitory control capacities may not be sufficient in order to help people with emotional eating to regulate their food intake.
