I know I am replying to an older post, however, many travel for work these days.
Many hotels have small fridges and if not in the room, one can be requested. A quick trip to the store your first night/day of arrival may help.
Picking up your own water, fruit, snacks, veggies, cottage cheese, oatmeal, and what you need helps a lot.
Also, traveling w your own brand of protein packed in a container in your carry on bag (and a few of your own protein bars) helps as well.
These things don't take long and can save you from having to eat out as many times. You'll most likely still find yourself grabbing one meal a day, but it's much better than 3x a day. I find eating out, almost anywhere, and even being careful, still has way too many of the wrong fats, and hard to balance in a proper nutrition plan. (not saying you can never go out to eat at a restaurant, just not 2-3x every day and expect to stay on track-- Especially if you travel a lot w work).
Just travel ideas. We travel often and this is what helps us w macros.
