背景：零食通常含有高脂肪和高糖。因此，减少零食消费可能是一种有用的体重管理策略。然而，个体吃零食可能有各种各样的原因，对干预有不同的影响。目前的研究调查了超重和肥胖参与者吃正餐、“不健康”零食（即高脂肪或高糖零食）和“健康”零食的原因。方法：在5天的时间里，28只雄性和27只雌性完成了每次进食的食物日记。除了提供有关饮食类型和所吃食物的详细信息外，他们还对13种不同的饮食原因（从相关文献和试点研究中确定）进行了评分。结果：在总共1084次进食事件中，358次被编码为零食，其中79%是高脂肪或高糖的。结果显示，在所有事件中，分别有49%和55%的人认为饥饿和诱惑（外部进食）是吃不健康零食的原因。26%的人因为感到厌倦、无聊或有压力而吃东西（情绪性进食）。结论：这些发现指出了针对渴望、增强自我控制或促进刺激控制的干预策略的潜在效用。
Background: Snack foods are often high in fat and sugar. Thus, reducing snack consumption may be a useful weight management strategy. However, individuals may snack for a variety of reasons with different implications for intervention. The present study examined the perceived reasons for eating main meals, 'unhealthy' snacks (i.e. snacks high in fat or sugar) and 'healthy' snacks in overweight and obese participants.Methods: Over a period of 5 days, 28 males and 27 females completed a food diary every time they ate. As well as providing details about the type of eating episode and food eaten, they also rated their agreement with 13 different reasons for eating (identified from relevant literature and a pilot study).Results: Across a total of 1084 eating episodes, 358 were coded as snacks, 79% of which were high in either fat or sugar. The results showed that hunger and temptation (external eating) were reported as a reason for eating unhealthy snacks in 49% and 55% of all episodes, respectively. Eating because the individual was feeling fed up, bored or stressed (emotional eating) was given as a reason in 26% of episodes.Conclusions: These findings point to the potential utility of intervention strategies that target cravings, enhance self-control or promote stimulus control.
