Good plateau busters?

So, I am down 110 now and can't be more thrilled with my progress. I feel so different. Everything is easier not wearing that 100 lb backpack.

But I have a tremendous way to go (I want to lose 328 total) but am at a plateau. I have tried adding carbs enough to kick me out of ketosis for a day or so, fasting, and adding good calories for a while. Nothing breaks the plateau. I am limited on the amount of exercise I can do, so doing more of that is out.

So, I will KCKO without fail, but I didn't know if anyone had any luck in breaking their plateau aside from just waiting it out?
