Tokyo, Sept. 13 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000059063) titled 'Effects of Time-Restricted Eating on Body Weight and Physical Performance in Young Adults' on Sept. 12.

Study Type: Interventional

Study Design: Basic Design - Cross-over Randomization - Randomized Blinding - Open -no one is blinded Control - No treatment

Primary Sponsor: Institute - Hiroshima University

Condition: Condition - Not applicable (healthy adults) Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - This study aims to compare the effects of two types of time-restricted eating (TRE) - an early window (08:00-14:00) and a midday window (12:00-18:00) - on body weight, aerobic endurance, and anaerobic power in healthy young adults. Without any exercise intervention, this trial adopts a randomized crossover design to determine which eating window is more effective for improving metabolic and physical performance outcomes. Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - Early Time-Restricted Eating (eTRE): Participants were instructed to consume all meals within a 6-hour window between 08:00 and 14:00 each day, and to refrain from any caloric intake outside this window. The intervention lasted for 4 weeks, and no exercise intervention was implemented. Primary outcomes included changes in body weight, aerobic endurance, and anaerobic power. Interventions/Control_2 - Delayed Time-Restricted Eating (dTRE): Participants were instructed to consume all meals within a 6-hour window from 12:00 to 18:00 each day, and to refrain from any caloric intake outside this window. The intervention lasted for 4 weeks, with no exercise intervention. Primary outcomes included changes in body weight, aerobic endurance, and anaerobic power.
