why are you getting so worked up about fast results hun?
if you have 2 stone to lose i would try dropping your cals to between 1200 and 1500 and try and go for low gi/gl foods and ramp up the exercise, that would still produce very good results.
check out the 30 day shred dvd by jillian michels, lots of people having very good results with that one
free activitys, long walks, check you tube for fitness pod casts and follow them
