Your reflexive anti-vegetarianism has led you to totally misread the point. He said "that much" animal product, so it's safe to infer that he would not have a problem eating a smaller amount of meat. He didn't say it was disgusting to eat meat, he said it would be disgusting to gorge yourself for days on meat to stretch out your stomach.

And I agree with him, animals are delicious but if I eat too much meat at once I feel greasy and disgusting for days.
