Eh its real alright, I don't know why people don't call it "high blood sugar addiction". Fat blocks absorption of sugar. Fat+sugar = Tee Hee! Once a fat fuck acquires enough mass to strain their metabolism, they are rightfully miserable all the time except when the blood sugar is sky high to lift their mood. This feedback loop continues until they need high blood sugar just to feel normal (when Lord Beetus starts making himself at home) and then eventually just to feel less miserable while they are in orbit. That I believe is why properly medicated diabetics are such nasty people, and why compliance is difficult. The medication prevents the blood sugar spike from yielding a jolly fat fuck, and instead leaves a perpetually miserable, barely functioning blob. Of course, marijuana+constant snacking is there to save the day, and that is where you get the Jupiter-class planets that make it on TV on shows like My 600 Pound Life.
