Food is one of the intense pleasures in life. Food “liking” and “wanting” systems interact with regulatory mechanisms of hunger and satiety to control eating. So, what brain systems produce taste pleasure or “liking”? And what brain systems convert pleasure into “wanting” to eat? Neuroscientists have begun to answer these questions combining information from brain manipulation experiments in laboratory animals together with neuroimaging experiments in humans. In this chapter we review recent progress in (1) the identification of brain reward substrates of food pleasure and desire and how food becomes “liked” and “wanted”; (2) how “wanting” and “liking” systems interact with hunger and satiety mechanisms to influence eating; and (3) how dysfunction of “wanting” and “liking” systems might lead to overeating.
