How much weight would you lose?

Don't criticize, I couldn't give a ****. If on a daily basis I had lots of water, plain tea, 1-2 diet cokes, and 1 can of soup (80-100) calories (don't eat/drink anything except water after 7:00pm) would I lose weight? How much weight do you think I would lose on daily basis, or in a week? Just wonderiiing. Thankyou :)
