We examined the effect of three feeding conditions on cigarette smoking and coffee drinking in four healthy women. We hypothesized that food deprivation and changes in meal patterns would increase rates of smoking and coffee drinking based on extensive animal literature documenting this effect.
The conditions were: normal three meals per day containing usual energy intake, one meal per day (dinner time) containing 50% of usual energy intake, and three meals per day containing 50% of usual energy intake. Each condition lasted 3 days.
Neither reduction of energy intake nor alteration in the pattern of meals had any observable effect on number of cigarettes smoked, number of cups of coffee consumed, expired air carbon monoxide levels, or urges to smoke or drink coffee.
This study adds to the growing body of literature suggesting that the food deprivation effect observed in animals does not apply readily to humans. Reasons for the absence of this effect are discussed.
我们研究了三种进食条件对四名健康女性吸烟和喝咖啡行为的影响。基于大量记录了这种影响的动物文献，我们假设食物剥夺和进餐模式的改变会增加吸烟率和喝咖啡的频率。
这些条件分别为：每天正常三餐，摄入正常能量；每天一餐（晚餐时间），摄入正常能量的50%；每天三餐，摄入正常能量的50%。每个条件持续3天。
能量摄入的减少或进餐模式的改变对吸烟数量、饮用咖啡杯数、呼出气体一氧化碳水平或吸烟或喝咖啡的欲望均无任何可观察到的影响。
这项研究进一步补充了越来越多的文献，表明在动物身上观察到的食物剥夺效应并不容易适用于人类。文中讨论了不存在这种效应的原因。
