NCT06508255

Brief Summary

This study aims to investigate how time-restricted eating (TRE), more specifically TRE at different times (early vs late in the day), influences brain activity, behavior, decision-making, food intake, physical activity, the gut microbiome and metabolic processes. The study intervention procedure is a replication of that described in Peters et al. (2021).
