I don't believe in food addiction, at least I don't believe the fat logic of it.  Humans are hardwired to desire sugar and fat.  For early humans, it meant readily available food-energy.  In many cases, it allowed humans to continue on in existence.  I see shitlords talk about eating fast food and soda, the major difference between shit lords and planets is in quantity of garbage.  My point is I think shitlords and planets all desire and crave the same foods, it's just shitlords are the only ones who have even a touch of self control.  (I should note, I am a firm believer in whole foods and haven't had traditional fast food in several years--I think food chemicals are a major cause of cancer.)
