OK so if you don't eat for lets say a week how much does thar effect your body?Will you get any skinnier?With you working out everyday too.Also what damage would it do to you?Or if you only eat about 300 calories a day and still work out everyday.So if you did this for about a month how much would a 13 year old 105 girl loose?I don't really care about numbers I want to know about visible fat.By the way don't tell me not to do it because I don't give a ,thanks
