Remember he was trapped between two obeasts. So he could have said that "that one item has 3000 calories, 2000 from fat and 1000 from sugar."  And that would have been just details.   BUT he infringed on Obeast land by saying overeating isn't healthy. That's the delusional buttergolem territory, that eating 6000 calories a day and weighing 300 lbs is just as healthy as steel cut oatmeal.
