Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Single Group (Crossover)
Arm Title: Morning Meal (08:00) Arm Type: Experimental Intervention: Other: One-meal-a-day (OMAD) Arm Description: Participants consume a single standardized isocaloric meal at 08:00. Neurocognitive outcomes (ERP, resting-state EEG, Stroop performance) are assessed during morning (before meal) and afternoon (approximately 6 hours post-meal) sessions.
Arm Title: Midday Meal (12:30) Arm Type: Experimental Intervention: Other: One-meal-a-day (OMAD) Arm Description: Participants consume a single standardized isocaloric meal at 12:30. Neurocognitive outcomes (ERP, resting-state EEG, Stroop performance) are assessed during morning (before meal) and afternoon (approximately 6 hours post-meal) sessions.
Arm Title: Evening Meal (18:00) Arm Type: Experimental Intervention: Other: One-meal-a-day (OMAD) Arm Description: Participants consume a single standardized isocaloric meal at 18:00. Neurocognitive outcomes (ERP, resting-state EEG, Stroop performance) are assessed during morning (before mea
