I think, philosophically, the weight loss is and should be more "incidental" but like MANY people out there, I have some specific goals. I got down to an excellent maintainable low weight for me, at 119, and I am happy here though I want to keep improving body comp, strength, and endurance. I just want to be the best I can be and I think that whatever happens after this point, with continued tweaks and efforts, will just be icing on the meat-cake of primal. I just feel this is the healthiest, easiest to maintain lifestyle for me - that yields results, and keeps me constantly engaged and making the kind of efforts that don't feel like awful sacrifices but more like awesome challenges. So in short, yes I think it is possible, but I wouldn't worry about it too much (though we all do) it also has a lot to do with your starting weight and your patience and all of that...I IF too, and for me that sort of takes care of the maintenence part of things for me. It's another variable to play with - of many.
