If possible, plan ahead and conduct research for healthy restaurants near your hotel or convention center. Typically, vegetarian restaurants offer healthy fare, as do a handful of ethnic options, such as Lebanese or Greek food.

In addition, you do not always need to dine at a restaurant for your meals while you are traveling. One of the easiest ways to eat healthy during your trip is by planning ahead for your breakfast. You can pack bananas and apples, nuts and seeds, and a small pre-mixed protein shake in your suitcase. With these items, you can enjoy a healthy breakfast in your hotel room for your entire stay -- complete with protein, good fats, and even fruit!
