Re: how much will I burn?
That is doing TREMENDOUS harm. You will ruin your metabolism, trigger a raging starvation response which will actually help the body to store any fat it can rather than burn it, it will eat up any muscle tone you have, and flatten your immune system, just for starters. That is an anorexic mentality. Please consider seeking help. Or at least really educating yourself about your body. But please, please don't starve yourself.
