calories

That would be around 3.5lbs/week, and is not advisable.
Just continue what you're doing in a healthy way. Any further restriction wouldn't be helpful, if you are currently losing at a good rate.

hi i have been on mfp for around 6 weeks and have been able to lose just over a stone this is great but i don't really understand my calorie intake that im supposed to be having?.
i am 5ft 4in and weigh 190 pounds, i really want to lose around a stone in 4 weeks for my holiday (if that's possible) but don't know how many calories i should be consuming to do this any help appreciated

It's most likely not possible, and not recommended even if it were. 2 pounds a week is all the more you should expect to lose safely and sustainably.

Think of it this way: how long did it take you to put on a stone? Longer than 4 weeks, right? So does it make any sense to hope for it to come off that fast? Keep it slow and steady, don't set timelines that you most likely won't meet. That's just a recipe for failure and resulting poor self esteem.

While it IS possible if you exercise enough, it isn't advisable. The faster you lose the more likely you are to put it back on, and to have lose skin....
