While in general, calories are not a part of primal eating, I think if someone isn't losing or gaining or even maintaining the way that they want, they should at least glance at their caloric intake.
1 cup of almond butter has about 1580 calories. That's about the entire daily caloric need of an inactive 135 pound woman. I don't know the figures for men.
I don't know how big the jars are that you were eating, but I'm guessing you'd have to eat a coat closet full of brocolli to equal the same amount of calories.
I'm not advocating counting calories here, just trying to make a point about very concentrated fats. We are machines, but we are also emotional creatures who will seek out what we love. Eating anything you want just doesn't work for everyone. If you take in more fuel than you burn, you gain; if you take in less fuel than you burn, you lose.
As a comparison, olive oil has about the same calories as almond butter. Would you be comfortable consuming two jars a week of it?
Others may feel differently, but I don't wrestle bears, so I count of the calories while staying primal about 90/10.
