Olive oil isn't ideal for cooking because it decomposes at a low temperature.
For beef, I use coconut oil.
For vegetables, I use butter.
For chicken, I usually make soup, so I don't use any fat.
For salad, I use only lemon juice. I don't like oily leaves.
About the only time I use olive oil is for tapenades and tomato + basil salads.
5'0" female, 44 years old. Started Primal October 31, 2011, at a skinny fat 111.5 lbs. Low weight: 99.5 lb on a fast. Gained back to 111 on sugar cheat. Currently fighting off sugar/candy cravings with bulletproof cocoa and a little rice.
I (try to) follow by-the-book primal as advocated by Mark Sisson, except for whey powder and a bit of cream. I advocate a two-month strict adjustment for newbies. But everybody is different and should tweak Primal to their own needs.
