Meal timing fails to improve sleep, large TRE study finds

A 12-week trial of nearly 200 adults with overweight/obesity compared early, late, and flexible daily eating windows. Sleep duration, sleep quality, and mood were similar across all groups; the only notable difference was about 12 minutes more total sleep for early TRE vs usual care. The findings suggest that shifting dinner time alone is unlikely to meaningfully boost sleep, and practical decisions should be guided by personal schedules and hunger patterns rather than expecting a sleep payoff.
