these types of diets disrupt your metabolism and can cause it to become slower and slower over time.(which causes people to get fat). beleive it or not you need carbs for certain body functions... eating a balanced diet with everything in moderation will speed up your metabolism... what you are doing is really bad for you. there are certain nutrients in grains that your body needs.. how many calories are you taking in?? by the way if you are trying to avoid carbs apples and bananas are full of sugar carbs.
also it kinda sounds to me like you are starving yourself...
just lookin out for ya.. not trying to sound rude, just worried is all
