obesity, cognitive reappraisal deficits
OBESITY
This preliminary study utilized fNIRS to evaluate neural correlates of inhibition during a food-based reappraisal task in individuals with obesity. Contrary to hypotheses, we did not find a statistically significant link between BE status and activation of the PFC during attempted food-based reappraisal.Our finding that compared to the Watch condition, the Crave and Resist conditions were associated with significantly greater activation bilaterally in the medial superior frontal gyrus, dorsolateral areas, and middle frontal gyrus suggest that deficits in the PFC are a potential neural basis for food-based cognitive reappraisal deficits among individuals with obesity. This is consistent with several studies that have implicated the PFC in obesity [One possible explanation for the lack of significant differences in neural activation between those with and without BE is that BE is not linked to food-based reappraisal difficulties. However, this is unlikely given that other studies have implicated hypoactivation in the PFC [
