The Effect of Bariatric Surgery on Delay Discounting For Food and Money: a Longitudinal Study

We investigate differences in delay discounting (DD) between lean and obese individuals, and study how bariatric surgery–a drastic weight loss intervention-impacts DD. Two longitudinal studies show that obese people are more impatient for food (but not money) than lean individuals, and that surgery reduces impatience.
