Covariations in body mass index (BMI), physical activity, macronutrient intake, and the frequency of consumption of specific foods were examined among 82 men and 75 women participating in a behavioral weight loss program over a period of 18 months. Results of repeated measures analyses of covariance showed that BMI change was inversely related to change in physical activity and change in frequency of vegetable consumption. BMI change was positively related to change in calorie intake from fat and change in frequency of consumption of beef, hot dogs, and sweets. Change in fat calories predicted BMI change better than change in total calories. In addition, change in the frequency of consumption of specific foods accounted for a larger percentage of the variance in BMI change than did change in macronutrients (10.4% vs. 5.2%). No differences were found between predictors of weight loss vs. weight maintenance.
在参与一项为期18个月的行为减肥计划的82名男性和75名女性中，研究了体重指数（BMI）、身体活动、宏量营养素摄入量以及特定食物消费频率的协变情况。重复测量协方差分析结果显示，BMI变化与身体活动变化以及蔬菜消费频率变化呈负相关。BMI变化与来自脂肪的卡路里摄入量变化以及牛肉、热狗和甜食消费频率变化呈正相关。脂肪卡路里变化比总卡路里变化能更好地预测BMI变化。此外，特定食物消费频率的变化在BMI变化方差中所占百分比比宏量营养素变化所占百分比更大（10.4%对5.2%）。在减肥与维持体重的预测因素之间未发现差异。
