Obese enjoy food less and less

"Obese people expect to enjoy food more than lean people do, but when they eat, they enjoy it less, a brain study shows. And that's a problem. To make up for the missing enjoyment, obese people eat more high-calorie food. Overeating further dulls food enjoyment and locks people in a vicious circle. The finding comes from real-time brain-imaging studies in obese and lean women by Eric Stice, PhD, of the Oregon Research Institute, and colleagues" - WebMD
