对食物摄入量影响最大的因素之一是在吃饭的时候有熟悉的人在场：人们和朋友/家人一起吃饭时比独自吃饭时吃得多。但为什么会这样还不清楚。在两项研究中（研究1：N = 98;研究2：N = 120），我们发现，仅仅是对社交互动的预期就足以促进对大餐的选择，即使当一个人独自一人做出决定时，这种情况也会发生。当成年女性知道自己要在社交场合吃饭时，她们会给自己提供更多的食物，而不是当她们知道自己要独自吃饭时。这些数据表明，其他人如何影响我们的食物摄入量超越了特定的饮食环境，影响了餐前份量的决定，这表明我们需要从根本上改变对饮食的社会影响的想法。
One of the most powerful influences on food intake yet identified is the presence of familiar others at an eating occasion: people eat much more when they eat with friends/family than when they eat alone. But why this is the case is unclear. Across two studies (Study 1: N = 98; Study 2: N = 120), we found that the mere anticipation of social interaction is all that is needed to promote the selection of larger meals, and that this occurs even when a person is alone when they make their decision. Adult women served themselves larger portions when they knew they were going to eat socially versus when they knew they were going to eat alone. These data suggest that how other people influence our food intake reaches beyond the specific eating context to affect pre-meal portion size decisions, suggesting that a fundamental shift is required in our thinking about social influences on eating.
