Food Reward in Native American Women

Completed · Has a placebo group

Conditions studied: Obesity

In brief

This study aims to characterize the neurobiology of obesity in American Indians (AI) using functional MRIs to examine the correlation between brain response to food stimuli in AI women. A functional MRI (fMRI) is used to visualize brain activity when obese and lean AI women look at images of fattening food, non-fattening food and non-food objects. Additionally examined is the effect of the drug naltrexone to suppress brain response to visual food cues and calorie intake in the women.
