If you don't eat you die. Or you get smoked, like what happened to Michael Jackson.  (What do you mean smoked?) It blocks your lungs from breathing.  You know how you breath through your lungs like I'm breathing right now.  He was a singer, but he didn't eat that much and he kept eating junk food, so he got smoked.  He ate like 60 pieces of candy and then 2 pieces of broccoli.   Junk food fills your body and just blocks your lungs so he couldn't breath.
