I don't think you quite get the idea of how a high fat diet works in terms of health and weight loss if your asking this. Maybe you should ask that instead.
I think it varies for everyone. Initially, I was able to eat all the primal food I wanted and lost weight slowly the first month. I think once my body realized I was planning to continue to eat this way, I stopped losing. Once I started logging, and realized I was at about 2000 calories I started cutting back. Now I'm back to slowly losing at about 1500 calories. I only want to either weigh or look like I weigh 125, so only need to lose 6 more lbs. I am sure a heavier person might be able to do the all he/she wants for longer, but ultimately will need to monitor calories in order to reach the goal... Not exactly scientific, but an ongoing experiment...

Why do you think anyone eating above maintenance could lose weight?
The question is a tautology. The definition of weight loss or weight gain (once water weight has been factored out) is an energy deficit or surplus. The argument that keeps coming back around is whether the type of calories in affects the quantity of calories out. Not whether eating a lot of butter allows one to defy the laws of thermodynamics.
In other words, the argument you're looking for proof of doesn't exist, and is nothing but a great example of the term "straw man."
Do you think everybody here thinks they can binge on fat and lose weight? Do you think this is what Mark says in his book? If so you are wrong. You should read more about paleo nutrition and get a better grasp on what it is and why it works.

Well... I doubt you will find a study that shows that. I think people get this idea that primal allows them to eat what they want and lose weight, because initially this can happen. But often what's happening is that people aren't eating as many calories as they think they are. They're just feeling more satisfied with the food they're eating, so it may feel as if they're eating more (if that makes sense).
I had to try to explain to someone last night that I can't eat wheat products because they make me crave more wheat products, even when I'm not actually hungry. She was of the belief that I should use more self control... my point is that eating primal I don't NEED to use self control ALL THE FREAKIN TIME to avoid over eating. I just eat a meal with enough healthy fats, and voila I'm satisfied for hours!
The thing being, I never thought I was eating THAT much before I went primal. It was only after eating pizza the other week, that I realised I probably DID binge more when I didn't need to, because of the desire to eat after eating something that by rights, should have filled me.
So yeah, not sure how much sense I'm making . Obviously if you're eating primal and not losing weight (that you need to), or you're gaining weight (that you DON'T need to) you need to take the energy content of your food into consideration.
