Abstract

This systematic review aims to comprehensively evaluate the literature regarding the impact of variations in dietary intake, both between- and within-day, on adiposity and glucose metabolism. We included observational and experimental articles obtained from PubMed, Scopus, Cochrane Library, and gray literature until 9 October, 2023, evaluating the impact of between- or within-day variations in meal, energy, or macronutrient intake on these outcomes. Our focus was on adults aged ≥18 y, spanning both healthy individuals and those with type 2 diabetes mellitus (T2DM). Given the diverse range of exposures, treatments, and outcomes among the selected articles, we chose a qualitative synthesis approach to effectively analyze the data. Eighty articles from 43 observational and 37 experimental studies were included, involving 89,178 participants. Patterns of dietary intake variation were identified and systematically organized into distinct categories based on similarities. Between-day variations in dietary intake consisted of between-day variations in both the quantity consumed and meal timing. Meanwhile, within-day variations encompassed factors such as eating window, meal omission, within-day meal timing, within-day variation in dietary intake quantity, and temporal distribution. Despite mixed results, time-restricted eating was generally associated with lower adiposity. However, limited control for total daily energy intake (TDEI) suggests that the contribution of lower energy intake cannot be conclusively excluded. Conversely, the adverse effect of meal omission on glucose parameters was consistently supported by randomized trials. Interestingly, the results showed that consuming a substantial portion of TDEI in the morning may increase the likelihood of observing improvements in adiposity. Furthermore, inconsistencies in outcomes across articles examining the effects in healthy compared with T2DM populations, or in energy-sufficient compared with deficient individuals, indicate potential condition-specific effects. These findings support the need for further investigation into the effects of between- and within-day variations in dietary intake to better understand their impact on adiposity and glucose homeostasis.

成人日间和日内膳食摄入量的变化与肥胖和葡萄糖稳态之间的关系：系统综述。

本系统综述旨在全面评估有关日间和日内膳食摄入量变化对脂肪和糖代谢影响的文献。我们收录了截至 2023 年 10 月 9 日从 PubMed、Scopus、Cochrane 图书馆和灰色文献中获得的观察性和实验性文章，这些文章评估了日间或日内膳食、能量或宏量营养素摄入量的变化对这些结果的影响。我们的研究重点是年龄≥18 岁的成年人，包括健康人和 2 型糖尿病 (T2DM) 患者。鉴于所选文章的暴露、治疗和结果多种多样，我们选择了一种定性综合方法来有效地分析数据。我们纳入了来自 43 项观察性研究和 37 项实验性研究的 80 篇文章，涉及 89,178 名参与者。我们确定了膳食摄入量的变化模式，并根据相似性将其系统地分为不同的类别。膳食摄入量的日间变化包括摄入量和进餐时间的日间变化。同时，日内变化包括进食窗口、漏餐、日内进餐时间、日内膳食摄入量变化和时间分布等因素。尽管结果参差不齐，但限时进食通常与较低的脂肪含量有关。然而，由于对每日总能量摄入量（TDEI）的控制有限，因此不能最终排除能量摄入量较低的影响。相反，不进餐对血糖参数的不利影响得到了随机试验的一致支持。有趣的是，研究结果表明，早上摄入大量 TDEI 可能会增加观察到脂肪含量改善的可能性。此外，在研究健康人群与 T2DM 人群、能量充足人群与能量不足人群的效果的文章中，结果并不一致，这表明可能存在条件特异性效应。这些研究结果表明，有必要进一步研究膳食摄入量日间和日内变化的影响，以更好地了解它们对脂肪和葡萄糖稳态的影响。

期刊介绍： Advances in Nutrition (AN/Adv Nutr) publishes focused reviews on pivotal findings and recent research across all domains relevant to nutritional scientists and biomedical researchers. This encompasses nutrition-related research spanning biochemical, molecular, and genetic studies using experimental animal models, domestic animals, and human subjects. The journal also emphasizes clinical nutrition, epidemiology and public health, and nutrition education. Review articles concentrate on recent progress rather than broad historical developments. In addition to review articles, AN includes Perspectives, Letters to the Editor, and supplements. Supplement proposals require pre-approval by the editor before submission. The journal features reports and position papers from the American Society for Nutrition, summaries of major government and foundation reports, and Nutrient Information briefs providing crucial details about dietary requirements, food sources, deficiencies, and other essential nutrient information. All submissions with scientific content undergo peer review by the Editors or their designees prior to acceptance for publication.
