According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions, it's the beanpoles with big appetites you really need to avoid.
根据《消费者研究杂志》最近的一项研究，我们饮食搭档的体型和消费习惯都会影响我们的食物摄入量。与现有的研究相反，即你应该避免与订购大量食物的较重的人一起吃饭，你真的需要避开那些胃口大的瘦高个。
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
为了测试社会影响对饮食习惯的影响，研究人员进行了两个实验。在第一项研究中，95名本科女生被单独邀请到一个实验室，表面上参与了一项关于电影收视率的研究。电影开始前，每个女生都被要求自己吃点零食。研究人员雇佣的一名演员先抢走了她的食物。在自然状态下，这位演员的体重为105磅。但在另一种情况下，她穿着一套特别设计的肥西装，体重增加到180磅。
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took, significantly more when the actor was thin.
胖版和瘦版的演员都吃了大量的食物。参与者也跟着做了，吃了比平时更多的食物。然而，当演员瘦的时候，他们吃得更多。
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
在第二次测试中，一种情况下，瘦演员从零食碗里拿了两块糖。另一种情况下，她拿走了30块。结果与第一次测试相似：参与者也这样做了，但当瘦演员吃了30块糖果时，他们吃了更多的糖果。
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will l. Call it the “I’ll have what she's having” effect. However we’ll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because l seethe results of his eating habits, But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?
测试表明，当我们做出决定时，社会环境具有极大的影响力。如果这个参与者要吃得更多，我也会吃得更多。这称之为“我会吃她正在吃的东西”的效果。但是，我们将调整影响。如果一个超重的人吃了很多，我会稍微克制一下，因为我看到了他饮食习惯的结果，但如果一个瘦的人吃得很多，我也会效仿。如果他能吃得多，保持苗条，为什么我不能？
