I guess I need to stop eating red meat.

The last article I skimmed about this mentioned the group's other dietary intakes weren't necessarily taken into account either. Like you may have changed your diet like you mentioned, but what else are you eating aside from that? Not everyone who is eating red meat for every meal is concerned about what else they're taking in.
For the last two years my diet has consisted of primarily eggs, ground beef, ribeye steak, and every so often I have some wild caught salmon. I try to buy my beef from a local butcher but he often runs out so I do have to frequent the regular grocery store for my meat. As for my treats to myself I will have oatmeal every other week or so, and every time I do it gives me the worst gas and bloating, but I still love the taste. I also sometimes will make my father's baked beans recipe every couple months or so, and I pay for it when I eat that too.

I don't count any macros or calories, I just eat twice a day until I feel full. But if I had to guess it's between 2000-2500 a day depending on the size of steak I eat.

People can scream anecdotal all they want. But I am 50 years old and have not been in this good of health in 20 years.
