It's like Penny on My 600 Pound Life.  "Fat people don't eat all the time...sometimes, I have to force myself to eat." Notice how compulsive she is about stuffing herself with beetus.  "I'm not really a pepperoni girl, but, <shrugs> oh well  ...."--it's high-calorie beetus fuel, therefore I have to eat it even though I don't crave it!
