The Claim

Early and late time-restricted eating have no statistically significant difference in their effects on objective sleep metrics in women with overweight or obesity, although within-group improvements in sleep metrics were observed only in the early time-restricted eating group.

Description
1 study reviewed
In plain English

In women with overweight or obesity, early and late time-restricted eating produce similar changes in objective sleep measures, even though only early time-restricted eating was linked to sleep improvements within its own group.

See the scientific wording

Early and late time-restricted eating do not significantly differ in their effects on objective sleep metrics in women with overweight or obesity, despite within-group improvements only observed in early TRE.

Why this might work

Eating only during the day keeps the body's internal clock in sync with natural light and dark cycles. This prevents food digestion from interfering with the body's nighttime cooling and hormone changes needed for deep sleep. As a result, the body stays calmer at night, with fewer awakenings and more continuous sleep.

  1. Study: Early but not late time-restricted eating improves an actigraphy-estimated sleep quality in women with overweight or obesity: secondary analysis of the crossover ChronoFast trial

    The study directly compared eTRE and lTRE using within-subject crossover design and found no statistically significant differences in changes in sleep efficiency, SFI, or awakening length between the two interventions, despite eTRE showing within-group improvements.
