Food reward: brain substrates of wanting and liking.
What are the neural substrates of food reward? Are reward and pleasure identical? Can taste pleasure be assessed in animals? Is reward necessarily conscious? These questions have re-emerged in recent years, and there is now sufficient evidence to prompt re-examination of many preconceptions concerning reward and its relation to brain systems. This paper reviews evidence from many sources regard...
متن کاملReassessing wanting and liking in the study of mesolimbic influence on food intake.
Humans and animals such as rats and mice tend to overconsume calorie-dense foods, a phenomenon that likely contributes to obesity. One often-advanced explanation for why we preferentially consume sweet and fatty foods is that they are more "rewarding" than low-calorie foods. "Reward" has been subdivided into three interdependent psychological processes: hedonia (liking a food), reinforcement (f...
متن کاملThe impact of a junk-food diet during development on 'wanting' and 'liking'.
The global increase in obesity rates has been tied to the rise in junk-food availability and consumption. Increasingly, children are exposed to a junk-food diet during gestation and early development. Excessive consumption of junk-food during this period may negatively impact the development of brain motivation and reward pathways. In this study we investigated the effects of a chronic junk-foo...
متن کاملSubstrate oxidation influences liking, wanting, macronutrient selection, and consumption of food in humans.
BACKGROUND Several carbohydrate-based models of feeding have been described. The influence of the substrate oxidation rate on liking, wanting, and macronutrient selection, however, is not known in humans. OBJECTIVE The aim of this study was to investigate the influence of the substrate oxidation rate on the above variables. DESIGN A randomized 4-condition study was conducted in 16 normal-we...
متن کاملRoles of "Wanting" and "Liking" in Motivating Behavior: Gambling, Food, and Drug Addictions.
The motivation to seek out and consume rewards has evolutionarily been driven by the urge to fulfill physiological needs. However in a modern society dominated more by plenty than scarcity, we tend to think of motivation as fueled by the search for pleasure. Here, we argue that two separate but interconnected subcortical and unconscious processes direct motivation: "wanting" and "liking." These...
