is it even possible to go 8 days without food at all? only drinking water. im wondering cause i think you would like pass out by the second or third day, but maybe im wrong? my friend is doing this, she says its not for weight loss, but other reasons, so idk? i dont think she will be able to make it that long without passing out though. she is 16, 5'11" and 130lbs so she's already really skinny. is this healthy? will she faint or end up in the hospital?
