In a recent Tufts University study, researcher Susan Roberts and her team compared the brains of 50 women ranging in weight from lean to obese and discovered dramatic differences in how the brains of different women respond to food.
Participants were placed in an MRI scanner and shown images of foods ranging from green salads to chocolate and fried chicken. The results showed that the brains of lean women reacted more strongly to food choices high in protein and fiber. The brains of the heavier women, on the other hand, were more stimulated by fatty, high-calorie foods sometimes even approximating the reactions found in people addicted to drugs like heroin and nicotine.
Dr. Roberts suggested that all it would take to change the response is a bit of brain rewiring, using a technique called cognitive restructuring. This approach employs a range of therapeutic strategies to help identify and label and ultimately change perceptions.
You can start that rewiring process right away, using some research-tested techniques like switching the locations of healthy foods and junk food in your kitchen.
