The recent separation of non-eating disordered obesity into a subtype that is high in negative affect and a subtype that is low in negative affect led to the hypothesis that the two subtypes would show opposite eating responses to typical triggers of overeating. Overweight/obese and normal weight participants, clustered into high and low negative affect subtypes, took part in an experiment using a control condition and two typically disinhibiting manipulations: negative mood induction and tasty food exposure. In accordance with the hypothesis, the negative mood induction and the food exposure elicited overeating in the overweight/obese high negative affect subtype. The overweight/obese low negative affect subtype did not eat more after negative mood induction and food exposure than without a trigger for overeating. Likewise, the normal weight participants did not show differential responses to the three manipulations. The increased vulnerability to overeating in this non-eating disordered overweight/obese subtype that is characterized by increased negative affect shows that individual differences play a crucial role in the way overweight/obese people handle temptations of the current environment. Being characterized by high negative affect makes it more difficult for the overweight/obese to resist temptations. Future studies into non-eating disordered obesity should consider the existence of these two subtypes.
最近，非饮食失调性肥胖被分为消极情绪高的亚型和消极情绪低的亚型，这引发了一种假设，即这两种亚型在面对典型的暴饮暴食诱因时会表现出相反的饮食反应。超重/肥胖和正常体重的参与者被分为消极情绪高和消极情绪低的亚型，他们参与了一项实验，该实验采用了一个对照条件以及两种典型的去抑制操作：消极情绪诱导和美味食物暴露。与假设一致，消极情绪诱导和食物暴露导致超重/肥胖消极情绪高的亚型出现暴饮暴食。超重/肥胖消极情绪低的亚型在消极情绪诱导和食物暴露后，并没有比没有暴饮暴食诱因时吃得更多。同样，正常体重的参与者对这三种操作也没有表现出不同的反应。这种以消极情绪增加为特征的非饮食失调性超重/肥胖亚型中暴饮暴食易感性的增加表明，个体差异在超重/肥胖人群应对当前环境诱惑的方式中起着至关重要的作用。以消极情绪高为特征使得超重/肥胖者更难抵制诱惑。未来对非饮食失调性肥胖的研究应考虑这两种亚型的存在。
