Abstract

This study compared effects of exercise training and diet on impulsivity‐related behaviors as measured by delay discounting and related neurobiology in adults with overweight or obesity. We hypothesized that exercise versus diet would be associated with reduced delay discounting propensity (k) and increased response in brain regions involved in cognitive control (medial prefrontal cortex, anterior cingulate cortex, and bilateral anterior insulae).
