![]() This striking increase over a relatively short period of time has coincided with changes to the environment, in which energy-dense and palatable foods are increasingly available and served in larger portions. In 2008, an estimated 1.46 billion adults were overweight worldwide, and of these 502 million were obese. Overweight and obesity are a global problem. These processes contribute to what can be termed “hedonically driven eating” and represent viable targets for appetite control. Then it is questioned whether “liking” and “wanting” are involved in “food addiction.” We conclude that elevated “liking” and “wanting” are psychological markers of a susceptible phenotype for overconsumption. We examine the evidence that “liking” and “wanting” are involved in weight gain, obesity, and certain forms of disordered eating. Separate neural pathways exist to mediate these processes, and experimental behavioral methods have been developed to distinguish and to measure them separately in humans. A relevant issue in the hedonics of food consumption is the distinction between “liking” and “wanting” components of food reward. In an environment where energy-dense and highly palatable foods are ubiquitous, it seems plausible that the hedonic system of appetite control will play a primary role in eating behavior-undermining homeostatic processes and driving consumption beyond energy requirements.
