I wonder how much of this is cultural/emotional.

I'm ethnically Indian, and grew up with white rice as by far the dominant carb in my diet. To this day, I'm not particularly fond of bread (though I like crusty, soft-crumbed bread like french baguettes from time to time). However, if I go more than a week without a rice based dish, I crave it on a visceral level.

Which carb you crave is probably cultural, but craving of carbs seems to be pretty universal.

I can concur. Thats the one thing thats hard about switching, here in the Netherlands bread is THE lunch thing. I found low carb bread at the supermarket, so i can eat that, it has a lot less carbs. Lifesaver!

Really is, sucks too cause I love baking bread and making pizzas :P

Try making pizza crust with almond flour.

or cauliflower.

Nugget grocery stores has in their steamtables mini pizzas that use a cauliflower crust.

Maybe bread with real butter?
