Too lazy (to cook) and poor (from buying so much beetus) that they can't maintain a diet of quality food, either bought or homemade. Also, like a dog, they probably don't even taste it as they shovel it down the abyss. I've known many fats in my life and they were picky eaters who only liked bland food. Shitpeople know it isn't worth it to consume unnecessary calories, sugar, and fat unless it is damn good.
