允许大鼠自主选择饮食成分，独立控制蛋白质和能量（卡路里）的摄入。虽然每餐的绝对蛋白质消耗量几乎保持不变，但通过选择性地增加非蛋白质含量，从中光期到黑暗期，膳食量逐渐增加。因此，所选膳食的组成遵循蛋白质浓度从清淡膳食到深色膳食降低的每日节律。这些摄食节律的一致性表明蛋白质和能量摄入的短期调节是分开的。
Rats allowed to self-select dietary constitutents control their intake of protein and energy (calories) independently. Although absolute protein consumption per meal remains almost constant, meal size increases progressively from the mid-light period through the dark period by selective increases in the non-protein content. Hence the composition of selected meals follows a daily rhythm with protein concentration decreasing from light to dark meals. The consistency of these feeding rhythms indicates separate short-term regulation of protein and energy intakes.
