When I travel, I often go out of my way to secure rooms with at least a fridge...a microwave is a bonus. I do my own booking, so that I can control that. When I arrive, I scope out the nearest grocery store (starting with Whole Foods and working my way down to a regular store since I have pretty specific needs). Then I stock up. Breakfasts are usually nuked chicken sausages and fruit or in the absence of a microwave, hard boiled eggs, cold chicken, tuna or uncured salami or summer sausage with the fruit. I buy a container of quac, a small bag of carrots, pre-cut raw veggies and fruit to have in my room. I travel with almond butter packets, tuna pouches, apples, grape tomatoes, lara bars and raw nuts on my person. I've tried other things as well, but these have been the most successful for me.

In restaurants, I choose salads with a meat (typically chicken) most of the time unless its a splurge or nicer meal where I can get good cuts of steak or fish with veggies. A plain green salad topped with my handy tuna pouch is also a good choice.

The last two travel seasons for me (I travel most of the month of Sept/Oct and then again in Jan/Feb), I actually lost weight when it was all said and done.

Bear in mind, if there is a flight involved, you will see fluctuations in body hydration levels affecting what you see on the scale. Our bodies don't like to be pressurized like that! Additionally, even without a flight, any time you eat restaurant food, even if it's healthy, it tends to be higher in sodium also causing scale fluctuations.
