When you're traveling, you don't have to eat fast food. These are your options off the interstate system:
1) Fasting- Don't eat at all. Occasionally, this is good for us because it stimulates our hormonal system.
2) Gas Stations- Not the best thing in the world, but nuts and juices are better than all of the other options in gas stations.
3) Dining Apps- This is my favorite. Use Yelp or Urban Spoon to find a local restaurant that has some healthy options. For example, I was driving through Mobile recently and found an excellent Nepali Indian Restaurant called Yak the Katmandu and it was tasty and healthy. I've also found some good BBQ places like 3 Pigs, in Headland, AL where the vegetable options are plentiful along with delicious smoked "inside" Boston butt pork.
The next time you travel, consider your options before you eat anything you'll regret.
