When does 'emotional eating' turn into a full blown eating disorder ?

Emotional eating is very different from eating disorder. Emotional eating is when you become hungry during or after stress and due to it you tend to eat more. It is not eating disorder but very healthy response to stress as body needs more energy when it is under stress. Stress releases hormones which cause preparedness of body for fight or flight which means also higher energy consumption and higher appetite in this situation is just healthy response to stress. But i understand that being overweight for many of us isn't something healthy or pretty to see. Eating disorder is something very different. It is when person doesn't eat at all or purge after eating due to fear of being just a bit overweight as they see themselves ugly and horrific if they don't meet their irrational standards of being thin. In emotional eating these fears are not involved.
