If people stereotype obesity as lack of control (though not always true,) Anorexia is the stereotype of TOO MUCH control (to the detriment of the person.)
I'm still making my mind of the story. But in Anorexics, stimuli to food is registered differently compared to healthy and obese people. Sugar is very noticeable to anorexics. While for the obese, stimuli to sugar isn't as noticeable (possibly the reason why more is wanted.) Chocolate causes a big spike in anorexics, moderate for healthy, and small spikes in the obese.
When we think of a mouth savoring food that causes a rise in dopamine, it tends to cause those of healthy and obese populations happy. In anorexic people, dopamine actually causes anxiety. Amphetamine was given to test this. Obese and healthy populations felt great when on it while anorexics just didn't feel right (this is why you don't give a person with an anxiety disorder adhd medications.)
Hunger signals were also more apparent in the healthy and obese populations than it was in anorexic people. Anorexics have a very great perceived stimuli than actual stimuli, which is why something like a very finely made steak with all the garnishes left in front of an anorexic mind might cause that person to feel full (before he/she eats) but increases the hunger sensation in both normal and obese people.
Fascinating. They haven't found a gene that causes this response, or if there was a gene that causes this type of response.
