I think you have too few calories, I can give you my stats as comparision.
Height 5 10
weight 218 lbs - began at 267 lbs
work out : cross train 30 x 2
run: 45 min x4
my calories: 1759
If i plateau it isn't adding more activity it mostly falls to not enough calories and my body will cling because it not being fufilled.
Good luck, each day and week is different, look at the overall monthly total when things slow down, you still lose maybe at a slower pace, for me the first 40 was easy now its getting slower and more difficult, but its well worth it.
I hope this helped somewhat.
