Using data from a national survey of weight loss practices, this study examined those dieters who were of normal weight. Forty-seven percent of White women, 25% of Black women, and 16% of men currently trying to lose weight had a body mass index under 25. Women's primary motive was health improvement. Among normal-weight female dieters, 12% of Whites and 27% of Blacks were using risky strategies. Dieters were less likely than nondieters to smoke and reported better nutritional practices; however, they were not more likely to exercise, and their maximum weight fluctuation was 50% greater. Additional research on the consequences of dieting among normal-weight individuals is of high priority.
本研究利用一项全国性减肥实践调查的数据,对体重正常的节食者进行了调查。目前正在尝试减肥的白人女性中有47%、黑人女性中有25%、男性中有16%的体重指数低于25。女性的主要动机是改善健康。在体重正常的女性节食者中,12%的白人女性和27%的黑人女性采用了有风险的策略。节食者比不节食者吸烟的可能性更小,并且报告说有更好的营养习惯;然而,他们锻炼的可能性并没有更大,而且他们的最大体重波动要高出50%。对体重正常者节食后果进行更多研究具有高度优先性。
