I love the Primal WOE, I really do... but as a busy college student I don't always have time to cook a piece of meat and veggies for lunch (also I find I get really bored eating the same sort of thing repeatedly). I'm much happier when I have nuts or a little dairy thrown into my day, but I'm wondering (from a weight-maintenance point of view) which one is more favorable.

Dairy would be maybe 1/2 cup heavy whipping cream, with no additives, no sugar... just straight up dairy fat.
Nuts would be maybe 3 or 4 tablespoons of macadamia butter. Really fills me up.

If I'm keeping my calories in check, does one offer more benefits (or fewer drawbacks) than the other?
