Inducing food craving by means of non immersive virtual reality

Abstract

The binge behavior has been associated with elevated levels of food craving. Cue exposure therapy has been proposed as an effective treatment for binge behavior, facilitating the extinction of the association between the stimuli associated with binge eating and the craving response. The aim of this study is to evaluate whether exposure to food in virtual environments can produce craving levels consistent with individual differences in trait-craving and state-craving, such that they can be used in treatment programs based on cue exposure. The participants were exposed to 10 foods in four virtual environments using non immersive devices. Consistent with the predictions, individuals who had higher levels of trait-craving and state-craving showed a greater desire to eat during exposure to different virtual environments. These results are indicative of the validity of procedures based on food exposure in virtual environments to carry out interventions based on cue exposure techniques
