Keep some back up stuff at the house. Eggs are allways good; so is canned tuna. Know what you can eat at fast food joints. Go to thie sites and build meals. Most of them will break down each item and list the carbs for each. Wendys double cheese burger -tom, -onion, and -ket is awesome. Just remove the top un and eat it off of the bottom bun. Swap the frys for a cesar salid and you out the dook for under 5 carbs. Spend some time looking a labels of salad dressings at the store so you can choose low carb when eating out.

Good Luck!
