背景：研究表明，多样化会降低对低能量密度 (LED) 和高能量密度 (HED) 食物的习惯率，或者普遍降低反应率。 目的：我们评估了多样化对超重和瘦儿童的饮食动机习惯化的影响是否不同。 设计：超重和瘦儿童 (n=84) 被随机分配到不同的组中，这些组的选择取决于他们是否接受了自己最喜欢的食物或食物。 结果：超重儿童的习惯速度比非超重儿童慢（P=0.008），对各种食物的习惯速度比对相同食物的习惯速度慢（P=0.008）。
Background: Research has shown that variety reduces the rate of habituation, or a general reduction in the rate of responding, for low-energy-density (LED) and high-energy-density (HED) foods.Objective: We assessed whether the effects of variety on habituation of motivation to eat are different in overweight and lean children.Design: Overweight and lean children (n=84) were randomly assigned to groups that varied as to whether they received their favorite or a variety of LED or HED foods.Results: Habituation was slower for overweight than for nonoverweight children (P=0.008), for a variety of foods than for the same foods (P
