Beds outside of shaving all of the hair off your body, spending the two weeks on the toliet and sweating the fluid out of your body I can't think of much.
If you don't have to be that weight then don't sweat it (pun semi intended) stepping on the scales and seeing that you're a stone lighter won't make you 'a stone healthier' (there's no such thing). Just eat healthily keep active and train hard and you'll get there.
