Abstract

Of the 36 screened participants, 34 completed the study (completion rate 94.4%).

  • Body weight and fat mass significantly decreased in the early (TRE) group starting meals before noon.
  • Significant reductions in fasting glucose, fasting insulin, and serum triglyceride levels were observed after 4 weeks in the early TRE group.
  • The late TRE group, which started meals after noon, showed no significant changes except for a reduced triglyceride level.
  • Meal timing was altered by TRE, with the first meal delayed and the last meal shifted, but sleep duration and timing remained unchanged.
  • Protein intake increased from 19.2% to 22.6% due to snack packages, but no significant correlation was found between nutrient intakes and body composition changes.
  • No adverse events related to study participation were reported.
