I'm just curious what the goal of doing some sort of liquid/juiced vegetable diet is for you? I get what you're saying about stress and weight loss and feeling like you need to make a change, but unless that change is that you want to give up pooping I'm not sure what you expect to accomplish by trying this.

If you'd just like some advice for improving the diet and getting your energy levels up and generally feeling better and getting leaner then I know I'd be happy to help, and some other members like Miriel can certainly give some great advice too. But personally, I don't think a two week juice diet is going to do much for you, certainly not long term. Try it if you want though. Just be prepared to not poop for a while if you're straining out all of the fiber in what you're drinking.
