Eating for pleasure or just wanting to eat? Reconsidering sensory hedonic responses as a driver of obesity

Pleasure from foods can stimulate non-homoeostatic eating, and might therefore also potentially contribute toward obesity. However, obesity is not reliably associated with heightened hedonic responses to foods. This apparent discrepancy may reflect the differentiation between liking and wanting. Supporting this, behavioural and neurophysiological data on responsiveness to food-related cues indicate that obesity may be associated with increased motivation for food consumption, without necessarily any greater explicit pleasure derived from the orosensory experience of eating. This distinction may have important implications for further research, and applications in commercial and public health approaches to modifying energy intakes. (c) 2006 Elsevier Ltd.
