Food choices, nutrient intakes, activity patterns and restrained eating scores were obtained from 249 normal-weight, young adults using self-reported questionnaires. Restrained eaters reported that they consumed more fat-free dairy products, fewer full-fat dairy products, fewer servings of fats and oils, less red meat and more fruits and vegetables than unrestrained eaters. In contrast to previous research, we found no overall difference in estimated daily energy intakes between restrained and unrestrained eaters, although there was a strong trend for restrained men to consume fewer calories per day. However, restrained eaters consumed less fat and more carbohydrate than unrestrained eaters. Restrained eaters in general were not more physically active than unrestrained eaters, but among the most active women, the restrained eaters were estimated to consume 13.3% less fat then the unrestrained eaters. This relationship was not observed in men. These data suggest that: (1) restrained eating influenced macronutrient composition in our respondents, but these effects were somewhat different in men and women; and (2) exercise played an important role in the dieting practices of restrained women but not restrained men. Examining only the food intakes of restrained women without considering their physical activity patterns may provide an incomplete picture of their dieting strategies.
通过自我报告问卷,从249名体重正常的年轻成年人中获取了食物选择、营养素摄入量、活动模式和节食得分。与非节食者相比,节食者报告称他们食用了更多的无脂乳制品,更少的全脂乳制品,更少份数的油脂,更少的红肉以及更多的水果和蔬菜。与之前的研究不同,我们发现节食者和非节食者在估计每日能量摄入量上没有总体差异,尽管节食的男性有每天摄入更少卡路里的强烈趋势。然而,节食者比非节食者摄入的脂肪更少,碳水化合物更多。总体而言,节食者并不比非节食者更爱运动,但在最活跃的女性中,节食者摄入的脂肪比非节食者估计少13.3%。在男性中未观察到这种关系。这些数据表明:(1)节食影响了我们受访者的宏量营养素组成,但这些影响在男性和女性中略有不同;(2)运动在节食女性的节食行为中起重要作用,但在节食男性中并非如此。仅研究节食女性的食物摄入量而不考虑她们的身体活动模式,可能无法全面了解她们的节食策略。
