Chrononutrition strategies, including time-restricted eating and Mediterranean dietary patterns, improve sleep quality, glycemic control, inflammation, and metabolic health.

This narrative review of 112 studies found that chrononutrition approaches such as time-restricted eating and Mediterranean diets are associated with beneficial effects on sleep quality, glycemic control, inflammation, and metabolic health. The evidence suggests these strategies may help prevent and manage cardiometabolic diseases, with sex-specific differences noted.

Frequently Asked Questions

What is chrononutrition?▼

Chrononutrition is the study of how the timing of food intake affects health, particularly in relation to circadian rhythms and metabolic processes.

Does time-restricted eating improve sleep quality?▼

The review suggests that time-restricted eating can improve sleep quality by aligning eating patterns with circadian rhythms and reducing metabolic disturbances.

Are there sex differences in response to chrononutrition?▼

Yes, the review notes sex-specific differences, with women showing greater vulnerability to sleep-related appetite disturbances and men having higher prevalence of visceral adiposity and hypertension.

What mechanisms link chrononutrition to metabolic health?▼

Chrononutrition influences hormonal pathways involving leptin, ghrelin, cortisol, and melatonin, and interacts with gut microbiota rhythmicity to regulate metabolism and inflammation.
