Abstract

Many studies have reported that specific susceptibility to food cues plays an important role in disordered eating behavior. However, whether restraint status modulates the neural bases of attentional bias to different types of food cues remains unknown. Thus, functional magnetic resonance imaging (fMRI) was conducted in individuals (12 restraint eaters, 12 unrestraint eaters) exposed to high/low-energy food and neutral images while performing a two-choice oddball task. The results indicated that restrained eaters responded more quickly to high-energy food images than to neutral and low-energy food images. More notably, compared with unrestrained eaters, restrained eaters showed faster reaction times, hyperactivation in a much wider array of reward (e.g., insula/orbitofrontal cortex), attention (superior frontal gyrus) and visual processing (e.g., superior temporal gyrus) regions, and hypo-activation in cognitive control areas (e.g., anterior cingulate) in response to high-energy food cues. Furthermore, among restrained eaters, the longest reaction times were found for low-energy food images, and activation of the attention and visual-related cortex (e.g., superior parietal gyrus) in the low–neutral contrast condition was significantly stronger than in unrestrained eaters. These findings contribute to our understanding of susceptibility to food cues:in addition to the special sensitivity (attentional bias)to high-energy food images, restrained eaters may also be more sensitive (allocate more attentional resources) to low-energy food images. These potential neural bases of restrained eaters may help clarify why dieting to lose or maintain weight is so often unsuccessful.
