Special Issue Information

Dear Colleagues,

Eating behaviour, timing of food intake and lifestyles play a crucial role in shaping metabolic health and quality of life. Emerging evidence highlights the importance of circadian rhythms and chrononutrition in regulating physiological processes, influencing energy balance, metabolic pathways, sleep patterns, and well-being. At the same time, behavioral determinants interact in complex and dynamic ways, contributing either to metabolic regulation or to increased risk for chronic conditions.

This Special Issue aims to contribute to the understanding of how lifestyle and behavioral factors, including chrononutrition and eating behaviour, affect metabolic outcomes and quality of life across the lifespan. We welcome manuscripts describing quantitative, qualitative, or mixed-methods original research from interdisciplinary perspectives such as nutrition, psychology, medicine, chronobiology, and public health. Studies on instrument development and evaluation, as well as systematic reviews and meta-analyses relevant to the lifestyle behaviors, chrononutrition, metabolic health and related outcomes are also encouraged.

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.

Background and aims: Reward-based eating reflects hedonic drivers of intake, including loss of control, diminished satiety, and preoccupation with food. We translated, adapted and studied the psychometric properties of the 13- and 5-item Reward-Based Eating Drive Scale (RED), for Portugal, Poland and Italy. Methods: A cross-cultural study was conducted with higher education students and general population samples (n = 1999). After translation and cultural adaptation, the RED was administered with food craving items, and collection of sociodemographic and anthropometric data. Factorial structure and measurement invariance were tested using confirmatory factor analysis (CFA), internal consistency with Cronbach’s alpha, and convergent validity via correlations with BMI and cravings. Results: CFA supported the expected structures of the RED-13 (three factors) and RED-X5 (unifactorial), with configural and metric invariance across countries and groups. Only partial scalar invariance was achieved for both versions. The RED-13 showed good to excellent internal consistency for total scores (0.868 ≤ α ≤ 0.906), with acceptable to good reliability for Loss of control (0.769 ≤ α ≤ 0.821), lower values for Lack of satiety (0.655 ≤ α ≤ 0.723), and good to excellent consistency for Preoccupation with food (0.881 ≤ α ≤ 0.918). The RED-X5 showed acceptable internal consistency (0.737 ≤ α ≤ 0.811) and correlated strongly with RED-13 (r = 0.949, p < 0.001). Both correlated positively with BMI and food cravings. Age, sex, and country had small to medium multivariate effects on RED scores. Conclusions: The RED-13 and RED-X5 showed good psychometric properties in Portugal, Poland, and Italy, with the RED-13 providing a multifactorial assessment and the RED-X5 offering a brief alternative.
