On a good day, 1200-1250 calories. Here are my rough macros:
Carbs are around 80 g (320 cal)
Protein around 77g (308 cal)
Balance is fat (600 cal)
So about 50% fat, and 25% carb and protein. I cheat often with 150-200 cal. It sounds like too few calories, but I'm only 5'0'" under 105 pounds, and sedentary. And the menu fills me up, so I figure I'm fine.
I do eat slivers of butter, but less than I used to. I used to eat a couple tablespoons, now I lose interest after about 1/2 tablespoon. If you try butter, I recommend the salted butter first. It has more flavor.
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.
