Neural correlates of dietary self-control in healthy adults: A meta-analysis of functional brain imaging studies
Han et al. (2018) conducted a meta-analysis on studies that employed functional magnetic resonance imaging, identifying the anterior insula, inferior and middle frontal gyrus, supplementary motor cortex and parietal cortices as core brain regions related to dietary self-control. The dorsolateral prefrontal cortex was singled out as a region that exhibited lower activation during self-control as a function of BMI. The researchers also investigated the impact of task by comparing 2 widely used paradigms: those requiring voluntary suppression of an appetitive response to cues, mostly assessing inhibitory control; and food decision-making (targeting cognitive value modulation). These tasks triggered distinctive regions belonging predominantly to cingulo-opercular or fronto-parietal networks, in addition to the common brain regions making up the core self-control network. In summary, there are core brain regions associated with dietary self-control and some distinct areas that may be involved depending on the target process.
