If you eat 500 calories and burn 12000 cals a week how long will it take to loose?

If you eat only 500 cal. & b burn 12000 cal./week. You will die a very painful & slow death!!!!! AnswerTheoretically, you would lose 3 pounds. However, a diet below 1200 for women and 2000 for men is dangerous. It is impossible to get all the nutrients your body needs to provide for muscle and energy on only 500 calories. You could end up with less muscle than you started with.
