Neural and Behavioral Mechanisms of Food Decision Making Across a Spectrum of Restrictive Eating

      Anorexia Nervosa (AN) is characterized by persistent dietary restriction that leads to starvation. Disturbed eating patterns are associated with poor long-term outcomes, including a high mortality rate. Yet, the neural mechanisms that guide extreme, pathological restrictive eating are unclear. We have shown that a computer-based Food Choice Task, which directly probes food-based decisions during functional MRI, captures the restrictive eating seen among individuals with AN, and is associated with actual caloric intake. Across two studies, we have shown that active decision-making about food among AN, relative to HC, was related to engagement of the dorsal striatum. This approach also offers an opportunity to examine variability in eating patterns.
