Recent evidence suggests that enhancing memory of the last meal decreases later snack intake, whereas disruption of encoding in memory of the last meal increases subsequent snack intake. Other studies have found that manipulating cognitions at the time of eating, such as beliefs about the timing and composition of meals, can affect subsequent intake. The effects of many of these cognitions are likely to depend on prior association in memory between situational and sensory cues and particular postingestional or affective consequences of eating. Hence, memory for the specific attributes of foods eaten in the recent past, and memory for the predicted consequences of eating acquired over repeated experiences are important influences on food intake. These data are consistent with evidence of hyperphagia in amnesic patients and laboratory animals with lesions to the hippocampus, an important substrate for learning and memory.
最近的证据表明，增强对最后一餐的记忆会减少随后的零食摄入量，而破坏对最后一餐的记忆编码则会增加随后的零食摄入量。其他研究发现，在进食时操纵认知，比如对进餐时间和食物构成的信念，会影响随后的摄入量。许多这些认知的影响可能取决于情境和感官线索与进食后特定的生理或情感后果在记忆中的先前关联。因此，对近期所吃食物的具体属性的记忆，以及对通过反复体验获得的进食预期后果的记忆，是影响食物摄入量的重要因素。这些数据与失忆症患者和海马体受损的实验动物出现食欲亢进的证据一致，海马体是学习和记忆的重要基础。
