The Claim

Women with overweight or obesity who have the poorest baseline sleep efficiency experience greater improvements in sleep efficiency and reduced awakening length during early time-restricted eating compared to those with higher baseline sleep efficiency.

Cause and effect
1 study reviewed
In plain English

Women with overweight or obesity who sleep poorly at the start of an early time-restricted eating program show larger improvements in sleep quality and fewer awakenings during the night than those who sleep better initially.

See the scientific wording

Women with overweight or obesity who have the poorest baseline sleep efficiency show the greatest improvements in sleep efficiency and awakening length during early time-restricted eating, suggesting that early eating may be particularly beneficial for those with existing sleep disturbances.

Why this might work

Eating only during the morning and early afternoon stops the body from digesting food at night, which lets body temperature and hormones like melatonin and insulin follow their natural daily patterns. This keeps the body calm during sleep, so it doesn't wake up as often and sleeps more deeply.

  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

    Women who slept poorly before trying early eating (only eating between 8 a.m. and 4 p.m.) ended up sleeping better at night — more efficiently and with fewer wake-ups — while those who slept okay didn’t improve as much. So early eating helped the ones who needed it most.
