I am very sensitive to fats, and some fats are Okay with me, and some just make me sick. Fried bacon or fried chicken or butter can give me nausea and upset stomach. That's why I go Paleo rather than Primal. He can eat paleo, which is actually quite low fat. It is Primal that is high in fat. How does he cook his meats that his stomach gets irritated? Is he frying them with huge amounts of oil or butter or cream or something like that? Does he spice it excessively? Is just broiling or boiling meat as is, under broiler solves the problem?
