Just a thought...if you are exercising that much and at that deficit, you may be overtraining and your body may be keeping in stasis in order to preserve itself????? To me, that amount of exercise seems excessive(unless it is your profession) and I can't imagine the body taking that lying down, so to speak. Sometimes too few calories or too much exercise can have a rebound effect in that the body tries to conserve its resources when unduly stressed.
What is your daily calorie limit?
And now that you don't have to be perfect, you can be good.
