text: what if i only drink water for a month no food?   well, you won't die. you will have horrific vitamin deficiencies. you will probably go into ketoacidosis which will eat up your muscle and damage your kidneys. then of course your metabolism will be shot to hell for good. you will also have to be eased back onto food after, it will be hard to keep anything down. ever see the videos from when the concentration camps were discovered? you'll look like that.
