It's because the ham brain is basically that of a toddler, they can't understand complex concepts or nuance so things always exist in nonsensical binaries for them. People either eat or don't eat. Phrases like "sometimes", "a little", and "at meal times" only exist to hams as prefixes to "teehee". Other popular examples include thin vs real, anorexic vs. 300lb+, healthy vs. already dead, and a woman being either "manly" (any muscle tone whatsoever while lacking excess fat) vs. "curvy" (morbid obesity with the largest body circumference at what should be the natural waist).
