Meal patterns in ground squirrels (Spermophilus lateralis) were recorded repeatedly over the course of endogenous circannual body weight cycles, with most data coming from the weight-gain phase. No manipulations were made, and the conditions were kept as constant as possible. Meal patterns were related to the level of food intake at each observation period. When the animals ate more, the most noticeable change was an elevated meal frequency. There were also some increases in meal size and the rate of ingestion. Postprandial correlations were generally positive, but rather variable and did not increase significantly when the animals ate more. On average 57% of the total intake occurred during the light phase of the LD 12:12 cycle. No systematic changes in the diurnality of feeding were detected. The meal patterns of hibernators when they are spontaneously hyperphagic show some resemblance to those seen in animals given exogenous insulin.
在松鼠（侧纹黄鼠）内源性年度体重循环过程中，多次记录了其进食模式，大部分数据来自体重增加阶段。未进行任何干预，条件尽可能保持恒定。进食模式与每个观察期的食物摄入量水平相关。当动物吃得更多时，最明显的变化是进食频率升高。进食量和摄食速率也有一些增加。餐后相关性一般为正，但相当多变，且当动物吃得更多时并未显著增加。平均而言，总摄入量的57%发生在12:12光照-黑暗循环的光照阶段。未检测到进食昼夜性的系统性变化。冬眠动物在自发食欲亢进时的进食模式与给予外源性胰岛素的动物的进食模式有一些相似之处。
