I believe exercise has been proven to help depression. Of course the endorphins can be addictive. Lots of people get addicted to it but there are worse things. I think depressives don't do it a lot because...well we are depressed and it can be impossible to get up the energy and motivation to do it. I can't do it when depressed. If I am doing good it is not problem.

I usually don't eat anything until dinner. I have no appetite until then. I have never viewed this as healthy though. I think it is unhealthy. My body has adapted to it. maybe three day or five day fasts would be helpful I do not know.
