A zero carb carnivore eats the same amount of meat as 98% of the world.
These kinds of claims are the reason why I can't take carnivores seriously.
You eat about 400g of beef a day. (some carnivores eat twice that or more. I'm making a conservative estimate) Not to mention some of the "fat" you eat is tallow. which is basically rendered from meat like beef or pork.
That's about 150kg of meat per year.
Most humans are in China and India. Chinese eat about 60kg of meat per year and India is 6 kg.
