“…Concerning our second hypothesis, task performance did not correlate with N2 or ERN mean amplitudes. This is in line with a previous study showing no effect of food-specific inhibitory control training on N2 amplitude (Carbine et al, 2021). However, the percentage of antisaccade errors in this study was highly correlated with the P3 mean amplitude of erroneous saccade trials, as well as partially correlated with correct saccade trials during T0, T1, T2 or during verum and sham stimulation.…”

Behavioural studies demonstrate alterations in cognitive functioning, particularly impaired response inhibition and increased attentional bias towards food in binge eating disorder (BED). This pilot study aimed to investigate the neurophysiological processing of a food-specific inhibition training combined with anodal transcranial direct current stimulation (tDCS) of the right dorsolateral prefrontal cortex (DLPFC) in 16 patients with BED (mean age = 38.6, mean BMI = 33.7 kg/m2). Patients performed a food-specific antisaccade task at baseline (T0) and in a cross-over design with verum vs. sham stimulation at T1 and T2. We investigated (i) event-related potentials (ERPs; N2, ERN and P3 amplitudes) while executing the task at baseline, (ii) whether baseline ERPs would predict task performance at T1 and T2 and (iii) associations between ERPs, eating disorder pathology and impulsivity at baseline. The mean amplitude of N2 was less pronounced in erroneous saccades (ES) than correct saccades (CS), whereas ERN and P3 mean amplitudes were more pronounced in ES. Moreover, the P3 mean amplitude of ES predicted the percentage of ES at both follow up-measurements irrespective of the applied stimulation (sham vs. verum). N2 in trials with correct saccades were negatively correlated with nonplanning trait impulsivity, while P3 in erroneous antisaccade trials was negatively correlated with food-related impulsivity. Overall, the findings of reduced ERN, enhanced P3 and N2 amplitude might be interpreted as difficulties in response inhibition towards food in individuals with BED. In particular, P3 predicts task outcome at follow-up and might represent a potential marker for inhibitory control processes.

“…Recently, inhibitory control training, which involves controlling ones impulses for task-oriented goals, is gaining momentum in the diet literature. 58 This approach might help understand the maintenance of weight loss after a particular intervention. This avenue of research has a lot of promise and will benefit from the machine learning tools in order to explore the neural mechanisms taking place.…”

“…Future studies may include the use of feature selection and machine learning algorithms to explore the effects of a variety of diets or other weight loss techniques such as bariatric surgery or mixed effects of diets and exercise in order to combat obesity. Recently, inhibitory control training, which involves controlling ones impulses for task‐oriented goals, is gaining momentum in the diet literature 58 . This approach might help understand the maintenance of weight loss after a particular intervention.…”

The rise of overweight and obesity across all age groups can be considered as an epidemic. A high body mass index not only has effects on longevity and quality of life of people who suffer from it but also has cognitive and neurological consequences. Executive function (EF)-or the neural regions that support it might act as causes of obesity. The aim of this study is to compare the differences between healthy and obese/overweight individuals and to understand how a prolonged diet of 2 months can affect EF event-related potential (ERP) components. Among the ERP metrics, N1, N2, and P3 are measured. Subjects underwent a diet program and their electroencephalogram was recorded every 4-6 weeks using a Stroop paradigm experiment. As the diet progressed, it was observed that perhaps more neural networks and executive control are engaged as the diet begins to take effect. Attention to nonfood increases and more control is exhibited when participants are presented with food images and food word stimuli.

“…For instance, recent studies have assessed the effect of multiple sessions of fGNG on body weight. While some studies found that fGNG facilitated weight loss [13][14][15][16], especially for individuals with a high body max index (BMI), others failed to observe an effect of fGNG on body weight [17][18][19][20][21]. Methodological heterogeneity complicates a direct comparison of these results, and thwarts the attempts to explain when fGNG can lead to durable effects.…”
