Why Juice Fast?

So why have I decided to juice fast? Well, to be honest I am working off of an impression more then anything. Sure it's a great way to lose weight fast. But what I want is to change my lifestyle, I'm not really looking for a quick fix. Part of my problem has always been eating to much. The fast is as much about learning to control my appetite as anything. Detoxing is also something I am interested in, I would like to give my body a little time to catch up and flush out some of those poisons I have put in. So thats why I am embarking on this juice fast.
