1kg of meat a day is a lot, but it obviously depends on what your diet is and what your body needs. This differs for all of us, so I can't say if you're making a mistake or not.

Some people can make do just fine with that but they're usually burning that off or actually consuming the excess protein from post-exercise recovery, even then, 1kg is still a lot.

A lot by how much, that depends on your body composition and the fat percentage of those steaks.

But anyway, on data: Red meats are classified as <probable carcinogenics> (key: probable). https://www.who.int/news-room/questions-and-answers/item/can...

Quantifying data: "The cancer risk related to the consumption of red meat is more difficult to estimate because the evidence that red meat causes cancer is not as strong. However, if the association of red meat and colorectal cancer were proven to be causal, data from the same studies suggest that the risk of colorectal cancer could increase by 17% for every 100 gram portion of red meat eaten daily."

What is not clear to me is if this was measured raw or cooked. Cooked meat will shrink and weigh less.

If I were you, I would just go get some checkups, see if you got any deficiencies or anything wrong that might be caused by your eating habits, and if not, just keep enjoying your 1kg of pork steak a day... anyway, I'm amazed you can eat that much pork in a single day, lol.
