For chicken, white meat contains less fat than dark meat. Try to buy boneless, skinless, chicken breasts. These contain relatively little fat. Turkey can be substituted for chicken.
Tuna can be purchased packed in oil or water. Tuna packed in water contains almost no fat. Tuna packed in oil contains considerably more fat.
Lowfat cream of mushroom and chicken soups are now available at your grocery store. Check the labels to see which one is lowest in total fat grams per serving.
Butter can be eliminated from some recipes. When browning onions, hamburger, etc., you can spray your skillet with nonstick spray or use chicken or beef broth instead of butter to cook with.
