If you calorie (plus sugar and carb) watch, you can budge past the plateau. Problems can arise if your body has got use to being underfed. It then lowers the metabolism to account for this. I find once in a two week period to do a binge day of upping my calories that day to my bodies full requirement of energy so as to trick it, into believing we are back normal eating. Then go back on the lower calories, taking into account changes needed if I have lost some lbs as the bench mark changes with different weight levels... Hope this helped.
