It depends on your definition of a plateau. For me, it's not a plateau until I hit the two month mark. I'm there now!
I can tell you that I finally just increased the exercise AND the calories and I'm hopeful that the fact that I've lost a couple ounces two days in a row now means I might be starting to lose again.
But generally speaking, no, increasing the calories does not work for me, only decreasing.
But I am of the opinion that you should eat as much as you can and still lose weight.
