The present research was designed to assess the amount of weight gain that would occur when male smokers in an inpatient setting were deprived of cigarettes for 10 days, and to evaluate factors that could contribute to that weight gain, such as caloric intake and activity level. Subjects were 17 healthy male smokers who either smoked ad libitum (n = 8) or quit smoking (n = 9) for 10 days after a 3 day smoking baseline. Caloric intake, activity levels, and body weight were assessed daily. Abstainers gained more weight than did smokers and ate more over time. There were no group differences in activity level. An analysis of energy needs versus actual energy intake suggests that caloric intake accounted for a large percentage of the post-cessation weight gain. However, considerable individual variability exists in caloric intake after smoking cessation. In addition, the study found post-cessation increases in caloric intake that were quite similar to those found in studies with females, suggesting that gender may have little to do with overall post-cessation caloric intake. Further research assessing dietary and metabolic changes after smoking cessation in a larger sample of both males and females is needed so that the reasons for and implications of dietary variability can be evaluated.
本研究旨在评估住院环境下男性吸烟者戒烟10天会增加的体重，并评估可能导致体重增加的因素，如热量摄入和活动水平。研究对象为17名健康男性吸烟者，他们在3天吸烟基线期后，要么随意吸烟（n = 8），要么戒烟10天（n = 9）。每天评估热量摄入、活动水平和体重。戒烟者比吸烟者体重增加更多，且随着时间推移食量更大。两组在活动水平上没有差异。对能量需求与实际能量摄入的分析表明，热量摄入在戒烟后体重增加中占很大比例。然而，戒烟后热量摄入存在相当大的个体差异。此外，该研究发现戒烟后热量摄入的增加与女性研究中的发现非常相似，这表明性别可能与总体戒烟后热量摄入关系不大。需要在更大规模的男性和女性样本中进一步研究评估戒烟后的饮食和代谢变化，以便评估饮食变异性的原因和影响。
