Yep, that's very low, so you can cut down protein and go high fat easily.
And last 10lbs is when things slow. Also best time to start measuring and checking body fat%.

I also found that moving around more helped a lot (not exercise, just more moving - housework, walking about). I only do it 2-3 times a week. Seems to wake the ol' metabolism up. And my house is cleaner, lol.
