Eating-window timing showed no clear sleep or mood advantage
Adults with overweight or obesity had no statistically significant differences in sleep, mood or quality of life when restricted eating schedules were added to Mediterranean diet education.

The 30-second takeaway
In adults with overweight or obesity, adding a restricted eating window to Mediterranean diet education did not produce statistically significant differences in sleep, mood or quality of life. Results were also nonsignificant between the eating schedules. These findings leave uncertainty about smaller changes and do not establish that the approaches have identical effects.
This was a secondary analysis covering a limited intervention period. The confidence intervals allow differences in either direction, so the absence of statistical significance does not establish equivalence or exclude every possible adverse effect.
What researchers found
Early eating window versus usual care
Over 12 weeks: mean difference 0.2 hours (95% confidence interval -0.2 to 0.6). Both groups received Mediterranean diet education.
The comparison included shared education
Every group received the Mediterranean diet education program. The trial therefore examined whether changing the eating window added differences beyond that shared program. It did not compare restricted eating with an entirely untreated group or an education-free approach.
Sleep and mood were measured differently
Sleep was measured with movement-monitoring devices before and near the end of the intervention. Depression, anxiety, stress and quality of life were assessed by questionnaires. None showed a statistically significant difference between restricted eating and usual care.
