This study examined the effect of time-restricted feeding on impulsivity in adults. Methods: Thirty adults aged 25-41 years participated in this randomized controlled trial. The intervention group followed time-restricted feeding for 4 weeks and there was no energy restriction in the intervention group (n = 15) or control group (n = 15). Impulsivity was assessed before and after the intervention with the Barratt Impulsiveness Scale and the Go/NoGo task. Results: The compliance rate (the percentage of days when participants had a feeding time of <= 8 hours/day) of the intervention group to the time-restricted feeding pattern was 92.38 +/- 4.24%. The Barratt Impulsiveness Scale-11 total score of the intervention group increased from 55.53 +/- 6.37 to 59.47 +/- 7.67 (p = 0.02). During the Go/NoGo task, an indicator of inhibitory control, the reaction time to food and non-food stimuli was significantly shortened in the intervention group (respectively; p = 0.009, p = 0.01). In the control group, no significant change was detected in impulsivity determined by the BIS-11 or Go/NoGo task. Discussion: This study showed that although time-restricted feeding may reduce body weight, it can lead to increased impulsivity and impaired inhibitory control.eninfo:eu-repo/semantics/closedAccessImpulsive BehaviorFeeding BehaviorFastingDietNutrition TherapyNeurosciencesNutritional SciencesFeeding And Eating DisordersArticle38648081WOS:0012070529000012-s2.0-85191148140N/A10.1080/1028415X.2024.2344139Q1
