Hey Dance....when I worked out with a personal trainer...many moons ago, he told me there was two ways to break a plateau. One was going hard at the gym with weights because it boost your metabolism and is thrown off by the "lacksadasical" as he would like to call it, workouts that your body is used to. He also encouraged cleansing but the problem with that is it isnt for everyone. But he said that alone would jump start a plateau. I never got to a plateau really because when I got to 170 I just threw in the towel so I cant give advice from my own experiences.
