Considering regular commercial grain fed beef doesn’t have the best nutrient profile for this and grass fed is optimal that really changes the price equation
If I were to do meat only it would require about 3lbs a day and 4 on some
Mix of half grass fed hamburger and half steak or roast would put my cost at about 40-60$ a day
Eggs and fish are carnivore too. Sardines are cheap.
Just checked, Walmart has 15oz cans of sardines in tomato sauce for $2.22. I drain and rinse, then eat he whole can of “five servings”.
