Neural Correlates of Stress- and Food Cue–Induced Food Craving in Obesity
OBJECTIVE Obesity is associated with alterations in corticolimbic-striatal brain regions involved in food motivation and reward. Stress and the presence of food cues may each motivate eating and engage corticolimibic-striatal neurocircuitry. It is unknown how these factors interact to influence brain responses and whether these interactions are influenced by obesity, insulin levels, and insulin...
متن کاملFood Cue Reactivity, Obesity, and Impulsivity: Are They Associated?
Heightened reactivity to food-associated cues and impulsive responding to these cues may be important contributors to the obesity epidemic. This article reviews the evidence for a role of food cue reactivity and impulsivity in food intake, body mass index, and weight-loss success. Inconsistencies in defining and measuring these constructs create difficulties in interpreting findings; however, e...
متن کاملOleoylethanolamide and human neural responses to food stimuli in obesity.
IMPORTANCE Obesity has emerged as a leading health threat but its biological basis remains insufficiently known, hampering the search for novel treatments. Here, we study oleoylethanolamide, a naturally occurring lipid that has been clearly implicated in weight regulation in animals. However, its role for weight regulation and obesity in humans is still unclear. OBJECTIVE To investigate assoc...
متن کاملApproach bias and cue reactivity towards food in people with high versus low levels of food craving.
OBJECTIVE Even though people suffering from high levels of food craving are aware of the negative consequences of binge eating, they cannot resist. Automatic action tendencies (i.e. approach bias) towards food cues that operate outside conscious control may contribute to this dysfunctional behavior. The present study aimed to examine whether people with high levels of food craving show a strong...
متن کاملCue reactivity and regulation of food intake.
A robust finding in eating research is the so-called counterregulation in restrained eaters. This means that while normal subjects eat less during a taste test, after they consumed a preload, restrained eaters consume more. An explanation is that food exposure causes stronger physiological preparatory reactivity in the restrained eaters. This reactivity is experienced as craving and leads to an...
