I had a couple of misperceptions that were hard to correct at first. One was that lean protein is always best. So I was, at first, eating mainly chicken for protein. Once I started eating hamburger (without concern for "leanness") and steak more often, my weight loss came easier, and I was more satisfied.

I had trouble learning that cottage cheese isn't really low carb. I associated it with protein and therefore it was "good." I notice that not too many succesful LCers who list meals in their journal seem to spend their carbs on cottage cheese.
