It focuses on meat, fresh fruits and vegetables, nuts, but not dairy products, legumes, or grains.
It recommends eating anything exists before agriculture discovered. So some fruit and vegetables are not allowed; like the night shade family (such as tomato, and eggplant). Also it promotes eating grass-fed beef, free- cage chicken, free-range eggs, and organic fruits and vegetables.
