How can I lose weight faster? I have already lost 4 stone but have a lot more to lose to be 8.5 stone.

Congratulations! 1 stone = 14 #s - so you have lost 56 #s! congratulations! with > 100 #s left - think you have already lost 30 %! the most important thing is variety - change up what you are doing if your at a plateau - re-group - if your seeing an md or nutritionist - ask for a new calorie goal - you are a different person now than you started this journey ( different starting weight now vs then) and your caloric restriction will be different now to continue seeing loss of weight. - same applies to exercise - muscle confusion is key- change-up your routine - add intervals - change intensity- keep up the good work! congrats!
