Many things happened when I switched from a low carb approach to a Primal lifestyle, but perhaps the biggest change was my attitude. I started questioning things. I no longer ate something simply because it was low carb; I now needed to know everything that was in my food, where it came from, and how it was made. Since a Primal diet didn’t allow for legumes, grains or processed foods, a lot of the foods I had eaten in the past – Atkins bars, low carb tortillas, and tofu to name a few – were off the list.
