In three cross-over experiments, we examined the effect on energy intake of changing the size of the plate used at a meal. On separate days, adults were served the same lunch menu but were given a different-sized plate. In the first study, 45 participants used each of three plate sizes (17, 22, or 26 cm) and served the main course from a large dish. In the second study, 30 participants received an equal amount of food presented on each of the two larger plates. In the third study, 44 participants used each of the three plates and selected from a buffet of five foods matched for energy density. Results showed that plate size had no significant effect on energy intake. The mean differences in intake using the smallest and largest plates in the three studies were 21+/-13 g, 11+/-13 g, and 4+/-18 g, respectively, equivalent to <142 kJ (34 kcal) and not significantly different from zero. Participants in the third study made significantly more trips to the buffet when they were given the smallest plate. These findings show that using a smaller plate did not lead to a reduction in food intake at meals eaten in the laboratory.
在三项交叉实验中，我们研究了用餐时更换餐盘尺寸对能量摄入的影响。在不同的日子里，为成年人提供相同的午餐菜单，但给他们不同尺寸的餐盘。在第一项研究中，45名参与者分别使用三种尺寸（17厘米、22厘米或26厘米）的餐盘，并从一个大盘子中取用主菜。在第二项研究中，30名参与者在两个较大尺寸的餐盘上分别获得等量的食物。在第三项研究中，44名参与者分别使用三种餐盘，并从能量密度相同的五种食物的自助餐中进行选择。结果表明，餐盘尺寸对能量摄入没有显著影响。在三项研究中，使用最小和最大餐盘时摄入量的平均差异分别为21±13克、11±13克和4±18克，相当于<142千焦（34千卡），且与零无显著差异。在第三项研究中，当给参与者最小尺寸的餐盘时，他们去自助餐台的次数显著更多。这些发现表明，在实验室用餐时，使用较小的餐盘并不会导致食物摄入量减少。
