人们在和熟悉的人一起吃饭时比独自吃饭时吃得更多。然而，目前尚不清楚社交性饮食是否会影响长期的摄入量。研究1的目的是检查社会促进摄入是否在所有膳食和连续三天中持续。研究2的目的是检查在实验室中的社会膳食期间增加的摄入量是否在自由生活条件下得到补偿。在研究1中，成年女性（n = 26）在三天内与朋友或单独在平衡交叉设计中吃了所有的饭菜。在研究2中，成年女性（n = 63）在实验室单独或与两个朋友一起用餐，然后使用电子食物日记软件记录他们在接下来三天的饮食。在研究1中，社交条件下3天内的摄入量（M = 7310 kcal，SD = 1114）显著高于单独条件下（M = 6770 kcal，SD = 974）（F（1，423）= 16.10，p <0.001，d = 0.51）。在研究2中，参与者在实验室中与朋友一起吃饭时（M = 1209 kcal，SD = 340）比单独吃饭时（M = 962 kcal，SD = 301）消耗更多（F（1，63）= 13.28，p = 0.001，d = 0.77）。食物日记数据加实验室摄入量的分析显示，4天后，社交条件下的摄入量（M = 6396 kcal，SD = 1470）显著高于单独条件下的摄入量（M = 5776 kcal，SD = 1182）（F（1，59）= 5.59，p = 0.021，d = 0.05）。这些结果表明，进食的社会促进作用持续了三天，并表明人们未能补偿进食的社会促进作用。
People eat more when they eat a meal with familiar others than they do when eating alone. However, it is unknown whether eating socially impacts intake over the longer-term. The aim of Study 1 was to examine whether socially facilitated intake is sustained across all meals and across three consecutive days. The aim of Study 2 was to examine whether increased intake during a social meal taken in the laboratory is compensated for under free-living conditions. In Study 1, adult women (n = 26) ate all their meals across three days either with a friend or alone in a counterbalanced cross-over design. In Study 2 adult women (n = 63) consumed a meal in the laboratory either alone or with two friends and then recorded everything they ate and drank for the next three days using electronic food diary software. In Study 1 intake across 3 days was significantly greater in the Social (M = 7310 kcal, SD = 1114) than in the Alone condition (M = 6770 kcal, SD = 974) (F(1,423) = 16.10, p < .001, d = 0.51). In Study 2 participants consumed significantly more in the laboratory when eating with their friends (M = 1209 kcal, SD = 340) than when eating alone (M = 962 kcal, SD = 301) (F(1,63) = 13.28, p = .001, d = 0.77). Analysis of food diary data plus laboratory intake showed that intake remained significantly greater in the Social (M = 6396 kcal, SD = 1470) than in the Alone condition after 4 days (M = 5776 kcal, SD = 1182) (F(1,59) = 5.59, p = .021, d = 0.05). These results show that social facilitation of eating is sustained over three days and suggest that people fail to compensate for the social facilitation of eating.
