Meal timing, nutritional status and diet quality in a group of Spanish children

Pediatr ObesPublished Cross-sectional study

Authors' conclusion

Later meal timing and a prolonged eating window were linked to poorer diet quality and unfavourable metabolic markers. It may be relevant to consider meal timing as a preventive health strategy in the development of future dietary guidelines.
