The potential effects of dishware size on energy intake are unclear, as many previous studies have been of low methodological quality. A newly published paper by Kosīte et al. (IJBNPA 10.1186/s12966-019-0826-1, 2019) reports findings from a rigorous, pre-registered investigation of the effects of manipulating plate size on total energy intake within a single eating occasion. This Editorial considers the implications of these new findings in light of previous evidence pertaining to the efficacy of behavioral nudges in particular, and in relation to contextual drivers of food consumption more generally. We conclude that the potential impact of behavioral nudges may have been exaggerated in the past, and call for future high-quality randomized controlled trials to establish whether reducing dishware size and other behavioral nudges might offer an effective complement to more comprehensive, multi-level interventions to reduce overconsumption of foods and beverages at a population-level.

较小的餐具可减少能量摄入：事实还是虚构？

餐具尺寸对能量摄入的潜在影响尚不清楚，因为许多先前的研究方法质量较低。Kosīte 等人新发表的论文。(IJBNPA 10.1186/s12966-019-0826-1, 2019) 报告了一项严格的、预先注册的调查结果，该调查涉及控制餐盘大小对单次饮食中总能量摄入的影响。本社论根据先前与行为助推功效有关的证据，以及与更广泛的食物消费的背景驱动因素有关的证据，考虑了这些新发现的影响。我们的结论是，行为助推的潜在影响在过去可能被夸大了，并呼吁未来进行高质量的随机对照试验，以确定减少餐具尺寸和其他行为助推是否可以为更全面、多层次的干预措施提供有效的补充减少人口食品和饮料的过度消费。
