在进食时，关于食用食物可能后果的信息可以增强对营养摄入的反应。例如，高能量饮料的饱足力通过微妙地操纵其感官特性来提高，以产生更强的饱足感期望。本研究测试了是否标记饱腹感信息也可以增强对营养摄入的反应。为了确保标签信息产生强烈的饱腹感预期，这项研究是在实验室外的一家研究餐厅进行的，伪装成消费者测试一家全国性超市的新品牌早餐产品。参与者在两个早晨来到餐厅，吃一顿固定的早餐粥加酸奶饮料，2小时后返回餐厅，随意饮用热饮和小吃。在一个测试日，参与者接受了低饱腹感版本的早餐（315千卡），另一天接受了高饱腹感版本（638千卡）。一半的参与者没有得到任何关于早餐的信息，一半的人收到了描述每种早餐的饱腹感的菜单，这些菜单与实际的能量含量和感官特征一致。食欲评级和上午的零食摄入量被用来评估对早餐的反应。参与者在高饱腹感早餐后消耗的零食明显减少，然而，提供有关早餐饱腹感的信息并没有改善这种反应。在现实世界中，明确的饱腹感信息并没有改变实际的饱腹感反应。
Information about the likely consequence of consuming a food, present at the time of eating, can enhance responses to nutrient ingestion. For example, the satiating power of a high energy beverage was improved by subtlety manipulating its sensory characteristics to generate stronger expectations of satiety. The present study tested whether labelled satiety information can also enhance responses to nutrient ingestion. To ensure that the labelled messages generated strong satiety expectations this study was run outside of the laboratory in a research restaurant under the guise of consumer testing for a national supermarket’s new brand of breakfast products. Participants came to the restaurant on two mornings to consume a fixed breakfast of porridge plus a yoghurt drink and returned 2 h later for ad libitum hot drinks and snacks. On one test day the participants received a low satiety version of the breakfast (315 kcal) and on the other day a high satiety version (638 kcal). Half of the participants were given no information about breakfasts and half received menus describing the satiating power of each of the breakfast consistent with the actual energy content and sensory characteristics. Appetite ratings and mid-morning intake of snacks were used to assess responses to the breakfasts. Participants consumed significantly less of the snacks after the high satiety breakfast, however, providing information about the satiating power of the breakfasts did not improve this response. In a real-world setting explicit satiety messages did not change actual satiety responses.
