Re: can i lose 2 stone in 3 months?
Three months is a good enough time. You won't reach your goal weight that soon but you'll defenitly be able to lose some (could be a lot), depending upon your eating and excercise habits. Whatever you do please don't start working out for 2 hours straight if you don't already have a work out routine. That is a very common mistake people make in hope to quickly lose weight.
Start slow i.e. 20-25 minutes of cardio, plus toning excercises, gradually increase the time, eat healthy/low fat meals, cut down on portions (please don't starve yourself, another common mistake people make) from TOMORROW. Report back here in three months time and tell us your success story. :D
