Abstract
While some individuals can defy the lure of temptation, many others find appetizing food irresistible. The goal of this study was to investigate the neuropsychological mechanisms that increase individuals' vulnerability to cue‐induced eating. Using ERPs, a direct measure of brain activity, we showed that individuals with larger late positive potentials in response to food‐related cues than to erotic images are more susceptible to cue‐induced eating and, in the presence of a palatable food option, eat more than twice as much as individuals with the opposite brain reactivity profile. By highlighting the presence of individual brain reactivity profiles associated with susceptibility to cue‐induced eating, these findings contribute to the understanding of the neurobiological basis of vulnerability to obesity.

We measured ERPs to a wide array of affectively charged visual stimuli and the number of chocolate candies eaten during a cued food delivery task
Summary
Over 62,000 photos are shared worldwide each day under the hashtag #foodporn (Mejova, Abbar, & Haddadi, 2016). These images glamorize the highly palatable, high‐calorie foods that are believed to promote the maladaptive eating patterns contributing to today’s obesity epidemic. Given the multifactorial nature of a complex disease like obesity (Gortmaker et al, 2011), grouping study participants into.
