I feel bad for the kid. Obviously something zapped the self-esteem from him. Not sure if his emotional overeating is a result of him not dealing with his parents separation, or sibling rivalry/favoritism, etc. Only some time on the Psychologists couch can pinpoint what led up to this. I think if he got mental help to deal with the self esteem issues, and got the required motivation to get into shape physically and mentally, he could change his life around completely.
