The brains of obese people seem to respond to a tasty treat with less vigor than the brains of their leaner peers, suggesting obese people may overeat to compensate for a reduced reward response, according to a new brain imaging and genetics study conducted by researchers at Yale University, The John B. Pierce Laboratory, the University of Texas and Oregon Research Institute.
