以在人群水平确定改变餐具尺寸是否可能有助于减少进食量， 115.0]) more calories (3%) compared to the small plate group (large: mean (SD)=644.1 (265.0) kcal，无法排除这一因素产生正面或负面有临床意义的影响的可能性， ， and examined potential modifying effects of executive function， 本研究的研究方案（https://osf.io/e3dfh/）和数据分析计划（https://osf.io/sh5u7/） 已在开放科学平台上预先注册，以往对低质量数据的荟萃分析可能大大高估了餐盘尺寸对进食量的影响， 没有明确证据表明两组的进食量存在差异：Cohens d=0.07（95% CI：0.27~0.41）， which has not previously been studied. Methods The setting was a purpose-built naturalistic eating behaviour laboratory. A general population sample of 134 adult participants (aged 1861years) was randomly allocated to one of two groups varying in the size of plate used for self-serving lunch: large or small. The primary outcome was amount of food energy (kcal) consumed during a meal. Additionally，请与我们接洽， Laura M.

The difference between the groups was not modified by individual characteristics. There was no evidence of impact on meal micro-structure， with the exception of more food being left on the plate when larger plates were used. Conclusions This study suggests that previous meta-analyses of a low-quality body of evidence may have considerably overestimated the effects of plate size on consumption. However， the possibility of a clinically significant effect in either direction cannot be excluded. Well-conducted trials of tableware size in real-world field settings are now needed to determine whether changing the size of tableware has potential to contribute to efforts to reduce consumption at population-level. （来源：科学网）
