Research the Food and Stock Up Upon Arrival

The more you can research and investigate prior to your trip, the easier it will be to maintain a healthy lifestyle while traveling.  To stay on track with your food, try to find a nearby grocery store or health food store, look up a couple of well rated restaurants that offer some healthy choices, and try to stay somewhere with a fridge (bonus for a kitchenette or full kitchen).  Knowing the lay of the land gives you an advantage as you’ll have an easier time finding healthy options for eating in and out.
