Moderate alcohol consumers obtain excess calories from alcohol and these additional calories do not result in weight gain. This study examined the contribution of alcohol to the total caloric intakes and expenditures of light to moderate alcohol consumers and compared the data to soda drinkers. Physical activity levels were measured by employing continuous heart rate monitoring for a 6-day normal phase and a 6-day abstinence phase. The normal food intake of both groups was recorded in diet diaries. Subjects' overall intake of food energy during the alcohol week was significantly higher than during any of the other three phases (an excess of 241 kcal/day). This study suggests that excess alcohol calories are compensated by an increase in energy expenditure, as evidenced indirectly by increased heart rates occurring between the hours of 2300 and 0700 h, increased self-reported nightly restlessness, increased wake time, and exercise.
适度饮酒者从酒精中获取额外热量，但这些额外热量并不会导致体重增加。本研究调查了轻度至中度饮酒者酒精对总热量摄入和消耗的贡献，并将数据与喝苏打水的人进行了比较。通过连续6天的正常阶段和6天的戒酒阶段进行心率监测来测量身体活动水平。两组的正常食物摄入量都记录在饮食日记中。受试者在饮酒周的食物能量总摄入量显著高于其他三个阶段中的任何一个阶段（每天多摄入241千卡）。这项研究表明，额外的酒精热量通过能量消耗的增加得到补偿，这间接表现为23:00至07:00之间心率增加、自我报告的夜间不安增加、醒着时间增加以及运动增加。
