在18个月的时间里，研究了82名男性和75名女性参与行为减肥计划的体重指数（BMI）、身体活动、常量营养素摄入量和特定食物消费频率的协变。重复测量的协方差分析结果显示，体重指数的变化呈负相关的变化，体力活动和蔬菜消费频率的变化。BMI的变化与脂肪热量摄入的变化以及牛肉、热狗和糖果消费频率的变化呈正相关。脂肪热量的变化比总热量的变化更能预测BMI的变化。此外，特定食物消费频率的变化对BMI变化的影响比常量营养素的变化更大（10.4%对5.2%）。体重减轻与体重维持的预测因素之间没有差异。
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.
