Psychological approaches to understanding satiation and satiety

Satiation, the processes leading to termination of a meal, and satiety, the state of inhibition over eating after a meal, both arise through the integration of cognitive, sensory and post-ingestive signals arising from consumption of foods and drinks. Although signals arising from nutrient ingestion are important, especially for satiety, both satiation and satiety are influenced by more cognitive aspects of the consumer experience. Recent research in particular highlights the importance of expectations about the likely effects of consumption and memories of effects of related products as elements of both satiation and satiety. This brief review assesses some of these psychological influences and discusses their implications for effective product development.
