Nutrition, Circadian Disruption and Cardiometabolic Health

Dear Colleagues,

In the industrialized world, many work and social activities are scheduled to occur at times when the internal biological clock (i.e., the circadian system) is promoting sleep, fasting, and inactivity. Wakefulness and eating during these biological times results in a disruption of the circadian system that, if chronically induced, is associated with not only impairments in safety, cognitive functioning, and sleep but also a multitude of poor health consequences, including metabolic syndrome, diabetes, and obesity. A growing body of literature has begun to recognize the importance of circadian disruption toward health; however, additional research is needed on the interaction between nutrition (what a person eats, how much a person eats, and when a person eats), circadian disruption, and cardiometabolic health. Importantly, mechanisms for adverse health need to be identified in order to create research-based countermeasures to help combat disease in those at risk of circadian disruption, including the >20% of the U.S. workforce that work shift hours and those that keep irregular sleep/wake schedules.

Original research at mechanistic, observational, and epidemiological levels on topics regarding nutrition, circadian disruption, and cardiometabolic health, including, but not limited to, topics focused on energy metabolism, meal timing, meal composition, and all aspects of health, are encouraged. Reviews of the literature are also welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
