Two groups of three subjects participated in a residential study that assessed the effects of varying the macronutrient and caloric content of a required lunch meal on subsequent food choice and intake. Lunches contained 431 or 844 kcal, with the caloric differential created by manipulating the calories derived from either fat or carbohydrate (CHO). Each lunch condition (high-fat, high-CHO, low-fat, and low-CHO) was examined for 3 consecutive days. Subjects controlled their own patterns of food intake and could consume any item or number of items at any time during the day or night. There were no significant differences in total daily caloric intake across conditions, indicating that subjects compensated for the caloric content of the lunch regardless of the macronutrient content. Total daily caloric intake under the high-fat and high-CHO conditions was 2824 +/- 151 (mean +/- SEM) and 2988 +/- 187 kcal, respectively, whereas intake under the low-fat and low-CHO conditions was 2700 +/- 131 and 2890 +/- 247 kcal, respectively.
两组各三名受试者参与了一项住院研究，该研究评估了规定午餐的常量营养素和热量含量变化对后续食物选择和摄入量的影响。午餐含有431千卡或844千卡热量，热量差异通过控制来自脂肪或碳水化合物（CHO）的热量来产生。每种午餐条件（高脂肪、高碳水化合物、低脂肪和低碳水化合物）连续测试3天。受试者自行控制食物摄入模式，可在白天或夜间的任何时间食用任何食物或任意数量的食物。不同条件下的每日总热量摄入没有显著差异，这表明无论常量营养素含量如何，受试者都会对午餐的热量含量进行补偿。高脂肪和高碳水化合物条件下的每日总热量摄入分别为2824±151（平均值±标准误）千卡和2988±187千卡，而低脂肪和低碳水化合物条件下的摄入量分别为2700±131千卡和2890±247千卡。
