Operative word being "ONLY." There's that whole "fat-burner" thing which you have to do first. Then you can compare primal calories out to primal calories in.Sigh, so many people still think it's only about calories in/calories out, and that is so obviously not true.
until i turned 42, it was true for me. not anymore.
5'0" female, 42 years old.
Started Primal October 31, 2011, at a skinny fat 111.5 lbs.
Current weight: 101.5. lbs and holding steady. Spring yardwork here we come!
Co-worker 1: Needs to lose ~50. Now he wants to start Mayo Clinic Diet. Yeesh. Give it up, man.
Co-worker 2: Needed to lose ~55. Lost 20 from stress. Started Primal in Sept, lost 20 more, but gained 10 back on a carb spree. We're working on it.

it worked great, and i was back in my very old size 6 jeans. until i turned 47 and my hormones went berserk and i have added 10 pounds that simply will not go. along with a bloated angry uterus that makes me look preggers. SUX.
i'd be a vegetarian if bacon grew on trees.
To me it's more about hunger/desire for food. If you eat a high fat/low carb meal and remain completely satiated for hours then you'll end up burning more fat than if you eat a high fat/high carb meal (of the same calories), get the insulin spike, store the fat and then experience hunger more rapidly and eat more later.
Of course, all else being equal the calories should be the same.
Still, since going primal and eating high fat/low carb my weight has started coming down quite easily, and I struggled for a looong time cutting the fat down and eating more carbs. So it seems that for ME this is the way to go. I am not everyone though . I also can't say what will happen down the track as I still have a lot of fat to lose and I may need to re-jig as I go along to keep the fat coming off.
For now, this is the easiest I've ever lost weight in my life (errm except when I was taking prescription diet drugs and lost desire for food ). I fully acknowledge that it's not going to be the same for everyone.
carbohyrdrates purpose is to be stored as fat. even a small meal of carb stops fat burning.
Luckily, your body is not that stupid, and your fat metabolism does not shut down when you eat oatmeal, and carbohydrate is a perfectly good source of energy for healthy people.
Today I will: Eat food, not poison. Plan for success, not settle for failure. Live my real life, not a virtual one. Move and grow, not sit and die.

No common energy currency: de novo lipogenesis as the road less traveled
Things like that make it really hard to believe the insulin hypothesis. For the cognitively dissonant who refuse to read the link, it basically says the body prioritizes oxidizing glucose over fatty acids, so in the presence of both--when consumed in excess of energy expenditure, in other words, too many calories--the body will store the fat and burn the glucose, thus making you... you know, fatter. De novo lipogenesis is possible, but far more common in the eat-whatever-the-hell-I-want-oh-look-cookies SAD eater than a young, Crossfitting paleo dieter who thinks they gained five pounds after eating a cookie because it spiked their blood sugar and insulin. Either way, it doesn't appear to contribute significantly to body fat stores except in the context of massive overfeeding with very little fat. That was written back in 2001. If there have been any significant additions to the literature on this subject since then, I encourage someone to share them.
tl;dr: Eat potatoes and enjoy them, damnit! (unless you're diabetic [but even diabetics have to admit that ketogenic low carb does not restore their insulin sensitivity; it simply keeps blood sugar in better check])
