Indulge yourself
If you are going to a foreign country for the very first time, then everything will seem new to you. This includes food and drinks. You will see that people over there use products and eat and drink dishes that are totally different from those consumed in your native country. You can have cheat meals during your vacations. Set a day on which you’ll indulge yourself and eat whatever you want: fatty foods, sugary snacks, and desserts. Enjoy your cheat days/meals but be careful.

Customize your meals
Health conscious travellers know that they can customize their meals. You can ask the cafeteria if they can exclude this or that product or ingredient if you dislike them and include something different instead. You can also ask them to prepare various oil-free dressings and less caloric toppings. Nowadays it is not a problem at all to eat out and still follow your diet plan.
