We all know how easy it is to go off your diet while traveling, but with a little discipline and some creativity, it is easier than you think to stay on track. Pack snacks as you go along. Packing snacks such as raisins, nuts, and dried fruits give you energy, but also keep you full and satisfied. Pay attention to the choices you make while dining out on vacation. Allow yourself one really indulgent meal the last evening of your vacation so you will have a reward to look forward to at the end of your trip. Incorporate your fellow travelers as accountability partners; let them in on your goals.
