Restraint theory has been used to model the process that produces binge eating. However, there is no satisfactory explanation for tendency of restrained eaters (REs) engage in counterregulatory eating, an ostensible analogue Using functional magnetic resonance imaging (fMRI), authors investigated brain activation normal weight REs (N = 9) and unrestrained (UREs; N 10) when fasted fed viewing pictures highly moderately palatable foods neutral objects. When foods, UREs showed widespread bilateral areas associated with hunger motivation, whereas only cerebellum, area previously implicated low-level processing appetitive stimuli. high palatability related satiation memory, desire, expectation reward, goal-defined behavior. These findings parallel those from behavioral research. The propose counterintuitive preload studies present study are due fact less hungry than find food more appealing fed.
