Not a good idea to starve AT ALL. What will happen is your body will go into starvation mode. IT thinks you are actually dying. So it will stop burning calories. I have seen a few dieticians (can't spell it) who all told me I don't eat enough. So EAT! Eat healthy! Starving will put yourself in the hospital - what good is that to anyone?? I have a friend DIE from starving herself please don't do this.
