help understanding my body

Hello I'm 24 5'5" and weigh between 128-130. I used to be around 145 and the first 15 took time but were achievable. I have been trying for a long time now (about 2 months) to get my weight down closer to 124 but those last 5 lbs won't budge. I eat an avg of 1300-1600 calories a day and run 3 miles two times a week and attend an hour long outdoor boot camp another 2 nights. Despite all this I can't seem to get the weight to budge. I know I'm at a healthy weight, but I have some weight on my stomach/butt that could be shed (im a pear shape) Any ideas on why the stall?

Hey! It seems like most of the suggestions for plateaus given by other CC'ers is to do something to shock your body a little! Have a day where you eat 1800 cals, vary your cals a bit over a week (one day 1300, one day 1700, one day 1400, one day 1800, etc), or do some exercise out of the normal (a weights class?). Hope this helps you and good luck!
