1. dealing with breakfast. everything else throughout the day was easy to do primal, but breakfast, my beloved cereal with banana and milk was so difficult for me to give up. now i have nut and coconut flake "cereal" with coco milk, protein powder, blueberries and a little banana. love it. although i try to have eggs n bacon when i'm up for it.
2. the extra time for food prep. i was already very much in the kitchen all the time making everything from scratch, but with taking out some of the cw snack and breakfast foods it's prep-time-all-the-time.
3. the cost of quality meat. once you go grass-fed, happy animals, you just can't go back. we accept that cost. we can taste the difference.
