Summary

Objectives: The purpose of this study is to examine how meal timing in a one-meal-a-day (OMAD) regimen influences neurocognitive outcomes. Methods: Twelve cognitively active participants (academics, students, software engineers) will complete three randomized OMAD conditions, consuming a standardized isocaloric meal at 08:00, 12:30, or 18:00. ERPs will be recorded during a computerized Stroop task to evaluate peak amplitudes and latencies under congruent and incongruent conditions. Resting-state EEG will be measured under eyes-open and eyes-closed conditions. Behavioral performance on the Stroop task, including reaction time and accuracy, will also be assessed.
