面对肥胖带来的不良健康后果，一个重要的问题是为什么有些人无法抗拒过度饮食。据推测，冲动性的增加至少在一定程度上导致了无法控制饮食行为。更冲动应该会让人更难以抗拒食物的摄入。对住宅环境中的 33 名肥胖儿童和 31 名瘦对照儿童进行了测试。冲动通过两种行为测量（抑制控制和对奖励的敏感性）和问卷来测量。结果表明，接受治疗的肥胖儿童比正常体重儿童对奖励更敏感，并且表现出更少的抑制控制。此外，暴食的肥胖儿童比不暴食的肥胖儿童更容易冲动。最有趣的发现是，抑制反应效果最差的儿童在住院治疗计划中体重减轻较少。总而言之：冲动是一种人格特征，可能对肥胖的发展、维持以及治疗产生至关重要的影响。
Facing the undesirable health consequences of being obese, an important question is why some people are not able to resist eating to excess. It is theorized that increased impulsivity at least partly underlies the inability to control eating behaviour; being more impulsive is supposed to make it more difficult to resist food intake. Thirty-three obese children in a residential setting and 31 lean control children are tested. Impulsivity is measured with two behavioural measures (inhibitory control and sensitivity to reward) and questionnaires. Results show that the obese children in treatment were more sensitive to reward and showed less inhibitory control than normal weight children. In addition, the obese children with eating binges were more impulsive than the obese children without eating binges. Most interesting finding was that the children that were the least effective in inhibiting responses, lost less weight in the residential treatment program. To conclude: impulsivity is a personality characteristic that potentially has crucial consequences for the development and maintenance, as well as treatment of obesity.
