Special Issue Information

Dear Colleagues,

Time-restricted feeding (TRF) has emerged as a promising approach to improving metabolic health and longevity, with growing evidence suggesting that the timing of food intake plays a pivotal role in regulating biological processes. This Special Issue seeks to explore the intersection between TRF and human health, focusing on its effects across a range of physiological systems, including metabolic function, circadian rhythms, weight management, and the prevention of chronic disease.

The aim of this Special Issue is to provide a comprehensive overview of current research, examining the underlying mechanisms through which TRF influences human health, as well as the potential clinical applications and public health implications of this dietary strategy. We welcome original research, reviews, and meta-analyses that explore the benefits and challenges associated with TRF in diverse populations, including those with obesity, diabetes, cardiovascular disease, and aging.

This field holds the potential to significantly improve public health, particularly as the prevalence of metabolic diseases continues to rise. As such, this Special Issue will highlight novel findings, methodological advances, and the translation of TRF interventions into clinical practice. We invite researchers to contribute to this dynamic and rapidly growing area of study, shaping the future of nutritional strategies for the promotion of health and well-being.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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.

Background/Objectives: Shift workers face higher risks of impaired glucose metabolism due to irregular eating habits and circadian misalignment. Time-restricted eating (TRE) could improve glucose metabolism by aligning food intake with the circadian clock, but its effectiveness remains unclear. Methods: Ten electronic databases (PubMed, EMBASE, Cochrane Library, CINAHL, PsycINFO, Scopus, Web of Science, ProQuest Dissertations and Theses, Science.gov, and ClinicalTrials.gov) were searched from journal inception to September 2024. Only randomized controlled trials (RCTs) involving shift workers were included. Meta-analyses with sensitivity analyses were conducted using a random-effects model to pool glucose metabolism and sleep outcomes, with heterogeneity and quality assessments performed. Results: Six RCTs were included. TRE demonstrated positive but non-significant effects on glucose metabolism outcomes: fasting blood glucose (weighted mean difference [WMD]: −0.02 mmol/L, 95% confidence interval [CI]: −0.13 to 0.10, I2 = 0%), fasting blood insulin (WMD: −5.77 pmol/L, 95% CI: −85.62 to 74.08, I2 = 92%), HOMA-IR (WMD: −0.50, 95% CI: −2.76 to 1.76, I2 = 82%), 2 h postprandial glucose (WMD: −0.65 mmol/L, 95% CI: −3.18 to 1.89, I2 = 86%), total sleep time (g = 0.07, 95% CI: −0.23 to 0.37, I2 = 0%), and sleep efficiency (g = −0.05, 95% CI: −0.63 to 0.53, I2 = 62%). Sensitivity analyses yielded similar findings, and overall certainty of evidence was rated ‘very low’. Conclusions: While TRE shows potential for improving the glucose metabolism in shift workers, current evidence remains inconclusive due to small sample sizes and study limitations. Future research should prioritize well-powered TRE RCTs in shift workers that adhere to a 6–10 h eating window. Incorporating early-TRE schedules with sleep hygiene may optimize metabolic outcomes, with circadian biomarkers analyzed to better elucidate the mechanistic pathway implicated. Full article
