I tried to detox for a few days by the rule of whenever I felt hungry, I would drink a smoothie or a cup of tea and supplemented my nutiriton with Vitamin tablets. It was tough but I looked loads less bloated.
You won't be able to tone up in that amount of time, but if you do loads on your cross trainer and turbotrainer (especially), then your muscles can swell for a couple of days after exercising giving the illusion that you're toned, even though it will wear down after a couple of days.
Be healthy though, don't do anything stupid just for an ex.
