Hey loseit!  I'm very near my weight goal, yet am inexplicably recently unable to lose weight.  In fact, if anything I'm gaining.  Does anyone have insight into what's going on?

**Stats**

5'3'', female, started diet at 157 pounds, goal is 113 pounds, currently 121.6 pounds.  Avoiding sugar & carbs, reducing calories.  Light/infrequent exercise.

**Background**

I started my diet in January of 2011, weighing 157 pounds.  I began by avoiding carbs and sugars, and later reduced my daily calories as well to about 800/day.  As you can see from [my weight chart over the past five months] this has worked pretty well.  Pretty well, that is, until about two weeks ago, when I became stuck around 119.  Suddenly, no amount of calorie reduction will get me lower than 119!  Over the holiday weekend I ate delishuz BBQ, and predictably went up to around 121.  Yet still, nothing will make me lose weight from there.  I've tried eating less and less to try and make my weight go down, but nothing works.  I have to admit that for the past three days I've eaten no food at all and only drank water, coffee, and Diet Coke, yet still my weight [will not go down and has slightly gone up]  I'm only 9 pounds to my goal, and I have no idea what the problem is. I don't even see how it's possible to gain weight over three days of fasting.

Since it may come up, I'm fairly sure I'm not pregnant since I have an IUD, but I'll get that tested today anyway.
