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.
