Chrononutrition is the study of how the timing of food intake affects human health. It is based on the idea that our bodies have an internal clock that regulates our metabolism, sleep-wake cycle, and other bodily functions.

The timing of food intake has long been recognized as an important factor in human health; when we eat in sync with our body's natural rhythms, we can improve our overall health and well-being. Recent research has shown that chrononutrition can have a significant impact on obesity, metabolic health, sleep, aging, and other aspects of health. However, chrononutrition research is still in its early stages and there are a number of gaps in the literature including: the effects of chrononutrition on different populations, (e.g., people with chronic diseases, the elderly); the long-term effects of chrononutrition; and the mechanisms by which chrononutrition works.

This Research Topic welcomes original research and review articles on the latest advances in chrononutrition. Topics of interest include, but are not limited to:

• The effects of chrononutrition on obesity, metabolic health, and other chronic diseases.
• The development of chrononutrition interventions for the prevention and treatment of chronic diseases.
• The role of chrononutrition in sleep and circadian rhythm disorders.
• The impact of chrononutrition on gut microbiota and immune function.
• The use of chrononutrition to improve athletic performance and recovery.
• The physiological and biological mechanisms involved in human chrononutrition.

We encourage submissions from a wide range of disciplines, including nutrition, biochemistry, physiology, endocrinology, sleep medicine, and sports medicine.

This Research Topic aims to collect publications in human studies only. Submissions involving animal models for human nutrition will not be accepted in this Research Topic.
