You think so? Think again!

Scientists at the Oregon Research Institute compared the brain responses of skinny and overweight people while drinking a milkshake. It turned out that a brain region called dorsal striatum, which the scientists describe as “a dopamine-rich pleasure center” became active. However, that brain region was less active in overweight people than in lean people.

Previous brain scans have already shown that overweight people have fewer dopamine receptors that normal weight people. This difference seems to be caused by genetics.

One of the senior scientists at the Oregon Research Institute concludes, based on the study results, that opposed to common belief obese people get in fact LESS satisfaction from food and to compensate for that they eat more.
