Here's the thing. You can't have your paleo almond flour cake and eat it too :)

If you don't want to count/measure/log your calories, then you really can't get that specific about your body percentage numbers. All you can do is try to eat a bit less while still getting as much nutrients as possible. Is it paleo to actually force yourself to eat less than what you body needs.. NO! But hey, we all wanna look good right?

So to me, I would honestly either do the best you can, and just focus on eating as clean a diet as possible, and try to avoid cheat meals and food that are very caloric dense (paleo treats, too much coconut milk, nuts, dried fruits, etc). OR, bite the bullet, realize that you are in the modern world, and damnit you wanna bf % in the low teens and monitor your intake and nail this caloric deficit down! That's what I do, and it helped my drop a few percentage points.
