Why do some people stop eating when depressed and others eat more??

While I certainly have no degree, I theor-ize that this has to do with nerve transmittors, or communication between the nerves and how many times they connect or don't connect. For example, junk food has carbs, calories and sugars, which according to my theory would cause the nerve ending to get moving, and thus provide a sense of relief from the depression...but again I have no degree on this matter and it is theory. From what I do understand about some depression pills, they effect the communication amongst nerve endings, and this is only a minor understanding of some pills, cuz not all work the same. You may find that a good run around they block, will make these type of munchies go away. The ones that don't eat and end up looking anorexic, do not end up in a better situation, cuz it is all still poor diet. Poor diet via starvation or over eatting starves the brain of food nutrients that it needs to survive, okay. Although one may appear thin and better off, it is only a cloak. I think, you just need to try other nerve stimulation, like 3 times a week, nothing to be married to or tied down to. Good luck.
