Abstract Background Reduced inhibitory control is associated with obesity and neuroimaging studies indicate that diminished prefrontal cortex activity influence eating behavior metabolism. The hypothalamus regulates energy homeostasis functionally connected to cortical subcortical regions especially the frontal areas. Objectives We tested network-targeted transcranial direct current stimulation (net-tDCS) excitability of brain involved in appetite control. Methods In a randomized, double-blind parallel group design, 44 adults overweight or (BMI 30.6 kg/m 2 , 52.3 % female) received active (anodal cathodal) sham 12-channel net-tDCS on appetite-control network for 25 minutes three consecutive days while performing Stop-Signal-Task measure response inhibition. Before after stimulation, state questionnaires assessed changes desire eat food craving. Directly participants breakfast buffet evaluate ad-libitum intake.

A growing body of research suggests exercise improves inhibitory control functions. We tested if exercise-related benefits extend to food-related and differ by calorie content, time day, weight status. One hundred thirty-eight individuals were pseudo-randomly assigned a morning or evening group. Each subject participated in two lab sessions where they completed questionnaires (rest session) walked on treadmill at 3.8mph (exercise for 45 min. After each session, participants both high-calorie low-calorie go/no-go task while N2 P3 event-related potentials (ERP), neural indicators control, measured. Participants also rated food images valence arousal. While difference amplitudes larger than foods, neither nor day affected results. Individuals had faster response times after without decreases accuracy. Arousal foods lower all compared exercise. In subset with obesity normal-weight individuals, exercise, Results suggest moderate did not affect generally, although may be beneficial improving early recruitment obesity. Moderate particularly the morning, help manage increased attention allocated food.

Inhibitory control, as an essential cognitive ability, affects the development of higher functions. Rhythmic perceptual stimulation has been used to improve abilities. It is unclear, however, whether it can be inhibitory control. This study Go/NoGo task and Stroop assess various levels control using rhythmic audio-visual stimuli stimulus mode. Sixty subjects were randomly divided into three groups receive 6 Hz, 10 white noise for 30 min. Two tasks completed by each subject both before after stimulus. Before task, closed-eye resting EEG data collected. The results showed no differences in behavioral measures among groups. While Hz reduced conflict effect only improved amplitude N2 component decreased score. Although did not enhance response inhibition, inhibition.

Increasing evidence suggests that targeting self-regulatory processes may improve obesity treatment outcomes. Incorporating gamification principles in inhibitory control training promote sustained adherence and resulting benefits. This pilot study evaluated the preliminary efficacy of supplementing an evidence-based weight management program (WW) with gamified (PolyRules!) on change Body Mass Index (BMI) among adults overweight/obesity.
