研究用餐大小的惯常方法认为，用餐过程中发生的“事件”会导致用餐的终止。然而，最近的研究表明，许多决定是在开始进食之前做出的，这些决定可能会影响饮食的大小。本研究试图解决关于餐量的三个关键研究问题：餐盘清洁发生的程度；餐前计划的流行率及其对餐量的影响；以及餐内体验的影响，特别是饱腹感的发展。为了解决这些问题，开发了一份基于互联网的大型队列调查问卷。结果表明，餐盘清洁在91%的餐食中发生，其中92%的病例从一开始就计划好了。餐盘清洁和饮食计划之间存在着显著的关系。餐前计划不愿在用餐过程中进行修改：只有18%的参与者报告消费偏离了预期。相比之下，28%的人报告继续吃到吃不饱，57%的人表示他们可以在用餐结束时吃得更多。Logistic回归分析证实，餐前计划是最重要的消费预测因素。总而言之，我们的发现证明了膳食计划作为决定膳食规模和能量摄入量的关键因素的重要性。(C)2011爱思唯尔有限公司。保留所有权利。
The customary approach to the study of meal size suggests that 'events' occurring during a meal lead to its termination. Recent research, however, suggests that a number of decisions are made before eating commences that may affect meal size. The present study sought to address three key research questions around meal size: the extent to which plate-cleaning occurs; prevalence of pre-meal planning and its influence on meal size; and the effect of within-meal experiences, notably the development of satiation. To address these, a large-cohort internet-based questionnaire was developed. Results showed that plate-cleaning occurred at 91% of meals, and was planned from the outset in 92% of these cases. A significant relationship between plate-cleaning and meal planning was observed. Pre-meal plans were resistant to modification over the course of the meal: only 18% of participants reported consumption that deviated from expected. By contrast, 28% reported continuing eating beyond satiation, and 57% stated that they could have eaten more at the end of the meal. Logistic regression confirmed pre-meal planning as the most important predictor of consumption. Together, our findings demonstrate the importance of meal planning as a key determinant of meal size and energy intake. (C) 2011 Elsevier Ltd. All rights reserved.
