The Claim

Time-restricted eating had no statistically significant effect on total sleep time or sleep efficiency in shift workers, with standardized mean differences of 0.07 and −0.05, respectively.

In plain English

In shift workers, eating within a restricted daily window did not change the total amount of sleep or the quality of sleep.

See the scientific wording

Time-restricted eating showed no statistically significant effect on total sleep time or sleep efficiency in shift workers, with standardized mean differences of 0.07 and −0.05 respectively, indicating negligible impact on sleep outcomes.

Why this might work

Working at night and eating during the wrong hours confuses the body's internal clock, which increases stress signals to the liver and pancreas, raising blood sugar and insulin resistance, but does not change how long or how well a person sleeps.

  1. Study: The Effectiveness of Time-Restricted Eating as an Intermittent Fasting Approach on Shift Workers’ Glucose Metabolism: A Systematic Review and Meta-Analysis

    The study found that eating only during a shorter window each day didn’t help shift workers sleep longer or better — the changes were so tiny they could’ve happened by chance.
