Fat should be 50-60% of your calories, and some Primals do 70-80% (I ften fall into this group). Everyone is different, but the general consensus is 50-60%. Just keep carbs low, and enjoy your fats. Seriously, I just can't do what some here do (count calories, carbs, fats, proteins). I will get extremely frustrated. I eat meals with lots of fats, moderate protein, and low-moderate carbs. Works for me.
