This sounds like it would get a bit boring after a while.
I have been eating just large amounts of different kinds of meats. Usually lean chicken, salmon with skin, fresh tuna, lamb or liver and serving it over a sweet potato or mashed cauliflower and often having some additional vegetables, but not always. Usually with a sauce (Sriracha or chipotle) or a salsa on top. Probably way more protein than I actually need. Only using grass-fed lamb fat or olive oil for cooking. No wine (maybe a glass a week), no chocolate.
I've been eating as big of portions as I can manage, but now and then with all that protein I have to skip a meal because I just can't eat it.
I've been able to make good progress in lifting weights. I actually got a couple of random compliments about my body composition (I honestly can't see it, but I guess they could). My pants certainly feel loose.
Anyway, I think the steak and eggs plan is probably brilliant but I doubt you have to be that strict with yourself.
