Ditto on planning!
Also I find it is really helpful to try and make my own breakfast (and maybe lunch) even when on the road. Instead of stopping at a restaurant, I will stop at a grocery and buy some yogurt and fruit, or you can get individual or two-pack hard boiled eggs from the deli section... or I'll pack some bagels and peanut butter and apples and bananas... for lunches you can often pick up pre-made salads (just go easy on the dressing) or other conveniently cut-up veggies and fruit... or packets of tuna salad with crackers... If you have access to hot water or microwave you can also pack things like instant oatmeal or soups...
When eating out, remember that most restaurants pad the plate to make it look like "Lots of quantity! Value!!" with a TON of unnecessary carbs. Your egg breakfast comes with toast AND hashbrowns AND pancakes. Your burger includes a bun AND fries AND macaroni salad... dinner might include pasta AND bread. I find it challenging in a weird sort of mental-emotional way to not-eat stuff that is served to me, and prefer to ask them to not bring the AND items at all, or to substitute something else (i.e. when i go for greek food, i ask them to hold the potatoes AND rice and just give me extra greek salad). Ditching the excessive servings of carbs from restaurant meals can improve the nutritional profile/calorie count quite significantly!
I would also recommend trying to avoid "fast" and "chain restaurant" food, and use your travel as an opportunity to try the "local fare." You will usually do much better nutritionally if you stop by some local deli-cafe and have a bowl of their homemade soup of the day, than you would at a fast food stop or "family restaurant." And - you get to enjoy stuff that you "don't get at home/don't eat every day."
