Chrono-nutrition and sleep: lessons from the temporal feature of eating patterns in human studies - A systematic scoping review

Almost 67% of the literature on the relationship between sleep and diet has emerged in the last six years.

• A systematic review identified three major dimensions of chrono-nutrition: meal timing, irregular eating patterns, and frequency of eating occasions.
• Meal timing studies included sub-dimensions such as breakfast skipping, late eating, and the comparison of earlier versus later meal schedules.
• Irregular eating patterns were primarily represented by diurnal fasting and intermittent fasting.
• The frequency of eating occasions was the least studied aspect, with only three relevant studies identified.
• Preliminary evidence suggests a link between the timing of eating patterns and various aspects of sleep health.
