I have to go to food tradeshows and the food on the floor is never primal and the hours are long so it's tough. You're right, I will have to better plan and take food along with me. I don't always rent a car when I travel so can't always get to a grocery store. When staying in a hotel sometimes they have a refrigerator sometimes not. Perhaps a sack of macadamia nuts to keep close by will help.
This coming week I have a 6 day work week and 5 days I'll be away from home.
I just have to figure out what works and do it!
