Goal Directed and Self-Control Systems in Bulimia Nervosa: An fMRI Study.

ABSTRACT:

Background

Binge eating is apparently the opposite of the strict control over food intake typically set by "maladaptive dieters". Using functional magnetic resonance imaging (fMRI), we investigated the role of goal-directed behaviors, and the related use of self-control, in binge-related food choices in patients with Bulimia Nervosa (BN).

Method

While undergoing fMRI, women aged 18-35 with BN (N = 35) and healthy control women (N = 26) rated foods for healthiness and tastiness and then made food choices on a 5 points Likert scale between two conflicting options: one food with lower healthiness and higher tastiness (defined as uncontrolled choice) than the other food (defined as controlled choice).

Results

BN and healthy participants made more uncontrolled than control
