I generally eat red meat two days a week either ground or whole muscle form.
As I usually eat 5 solid meals a day, each of them containing a protein, i may incorporate a 6-8 oz portion of beef in 2 or 3 of those meals.
So...bottom line...4-6 times a week.
The remainder is chicken,turkey,pork,lamb,veal,salmon,eggs.
I'm surrounded by meat 8 hours a day/6 days a week so keeping up with the variety is easy !
