Previous research, restricted to the laboratory, has found that restrained eaters overeat after they violate their diet. However, there has been no evidence showing that this same process occurs outside the lab. We hypothesized that outside of this artificial setting, restrained eaters would be able to control their eating. In Study 1, 127 participants reported hourly on their diet violations and eating over 2 days. In Study 2, 89 participants tracked their intake for 8 days, and 50 of these participants consumed a milk shake (a diet violation) on Day 7, as part of an ostensibly unrelated study. As hypothesized, dieters did not overeat following violations of their diet in either study. These findings are in contrast with those of previous lab studies and dispel the widely held belief that diet violations lead to overeating in everyday life.
先前的研究仅限于实验室环境，发现节食者在违反饮食规定后会过量进食。然而，尚无证据表明在实验室之外会发生同样的过程。我们假设，在这种人为环境之外，节食者能够控制自己的饮食。在研究 1 中，127 名参与者在两天内每小时报告一次饮食违规和进食情况。在研究 2 中，89 名参与者跟踪记录了他们 8 天的摄入量，其中 50 名参与者在第 7 天喝了奶昔（饮食违规），这是一项表面上不相关的研究的一部分。正如假设的那样，节食者在两项研究中都没有在违反饮食规定后过量进食。这些发现与之前的实验室研究结果形成对比，驳斥了人们普遍认为的饮食违规会导致日常生活中过量进食的观点。
