Rats in a laboratory foraging paradigm were offered each of four diets which differed in caloric density, and intakes, meal frequencies, meal sizes, and eating rates were monitored. The rats maintained a constant daily caloric intake by eating more frequent, larger meals of the lower density foods. However, caloric meal size was not regulated, and significant correlations between meal size and the length of the post-meal interval were rarely found. The 24-hour pattern of calorie intake was the same regardless of diet. Higher-calorie foods were consumed at a faster rate within meals than were lower-calorie foods. The feeding patterns observed suggest that caloric intake may be regulated over a time frame of several meals rather than on a meal-to-meal basis.
在实验室觅食范式中，给大鼠提供四种热量密度不同的饮食，并监测其摄入量、进餐频率、餐量和进食速度。大鼠通过更频繁地进食低密度食物的更大餐量来维持每日恒定的热量摄入。然而，热量餐量并未得到调节，餐量与餐后间隔时间之间很少发现显著相关性。无论饮食如何，24小时的热量摄入模式都是相同的。高热量食物在餐内的消耗速度比低热量食物快。观察到的进食模式表明，热量摄入可能是在几餐的时间范围内进行调节，而不是逐餐调节。
