The current investigation evaluated the effects of levels of restraint, dietary intake, and obesity on both immediate (i.e., in the laboratory) and subsequent (i.e., outside the laboratory) self-reported dietary intake. Subjects were 102 college females, half of whom were given a high-caloric snack of a chocolate milkshake. Subjects were classified according to their level of chronic dieting status and relative weight. Chronic dieting status was measured by utilizing both the Concern for Dieting (CD) and the Weight Fluctuation (WF) factors of the revised restraint scale (Polivy, 1980). When using the WF factor, results indicated that obesity interacted with dieting status on total food consumption (i.e., calories for the entire day). That is, nondieting obese subjects reportedly ate significantly more calories than nondieting normal-weight subjects. Further, nondieting overweight subjects reported eating significantly more than low-restrained normal-weight subjects. On the CD factor, restrained eaters who received a preload reported eating significantly more calories than nondieters at lunch. For those subjects not receiving a milkshake, restrained eaters ate fewer calories at lunch than nondieters. The significance of these results for understanding possible energy imbalances in obese individuals as well as understanding pathological overeating and its consequences is discussed.
当前的调查评估了限制水平、饮食摄入量和肥胖对即时（即在实验室中）和随后（即在实验室外）自我报告的饮食摄入量的影响。研究对象为102名大学女生，其中一半被给予了高热量的巧克力奶昔零食。根据她们的慢性节食状态和相对体重对研究对象进行分类。慢性节食状态通过使用修订后的克制量表（波利维，1980年）中的节食关注（CD）和体重波动（WF）因素来衡量。在使用WF因素时，结果表明肥胖与节食状态在总食物摄入量（即一整天的卡路里摄入量）上存在交互作用。也就是说，非节食肥胖受试者报告摄入的卡路里明显多于非节食正常体重受试者。此外，非节食超重受试者报告的摄入量明显多于低克制的正常体重受试者。在CD因素方面，接受预负荷的克制饮食者在午餐时报告摄入的卡路里明显多于非节食者。对于那些没有喝到奶昔的受试者，克制饮食者在午餐时摄入的卡路里比非节食者少。讨论了这些结果对于理解肥胖个体可能存在的能量失衡以及理解病理性暴饮暴食及其后果的意义。
