Abstract
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.
