You cannot abstain from food, you'll eventually die. This is the argument that most physicians bring up as well when talking about classifying food addiction as an actual addiction.   I have never heard a doctor say that, but I have heard a lot of fatties say it.  It's easy to debunk.  Ever notice how fat people hate most food that's considered healthy?  It's not all food they're supposedly addicted to.  The foods associated with addiction are those high in fat, salt, and sugar, since these are the most pleasurable to eat.  These would then be the ones they'd need to avoid.  In other words, they just have to just stop eating junk food.
