It has previously been found through observational techniques that moderate alcohol consumers tend to add alcohol calories to their diets without displacing macronutrient calories. The present investigation was an active manipulation of alcohol consumption to test for causation by instructing subjects to refrain from alcohol for five days. Twenty-five moderate alcohol consumers, identified with the Michigan Alcoholism Screening Test, were asked to complete a food intake diary for ten consecutive days during which they refrained from drinking any alcoholic beverages for either the first five days or the last five days. The subjects recorded in a diary everything they either ate or drank, the time at which the meal began and ended, their subjective state before and after the meal, and the number of other people present. Subjects' overall intake of food energy during the alcohol week was significantly higher than during the no alcohol week (2205 vs. 1829 kcal) and meals eaten during the alcohol week contained significantly more food energy than did meals eaten during the no alcohol week (649 vs. 541 kcal). Alcohol added additional calories to the diets without altering any other macronutrient intake. These results could have both health and weight loss implications.
此前通过观察技术发现，适度饮酒者倾向于在饮食中增加酒精热量，而不会取代常量营养素热量。本研究通过积极控制酒精摄入量来测试因果关系，方法是指示受试者戒酒五天。通过密歇根酒精ism筛查测试确定的25名适度饮酒者被要求连续十天完成一份食物摄入日记，在此期间，他们在前五天或后五天不饮用任何酒精饮料。受试者在日记中记录他们吃的或喝的所有东西、用餐开始和结束的时间、用餐前后的主观状态以及在场的其他人的数量。受试者在饮酒周的食物能量总摄入量显著高于无酒精周（2205千卡对1829千卡），饮酒周吃的餐食所含食物能量显著多于无酒精周吃的餐食（649千卡对541千卡）。酒精在不改变任何其他常量营养素摄入量的情况下，为饮食增加了额外的热量。这些结果可能对健康和减肥都有影响。
