One of the toughest things for me to battle as I spend 200 or so nights on the road is what to eat. Try getting a healthy meal traveling down I-75 or in a Super-8 or Red Roof Inn. It's just not going to happen unless you prepare! For me, that means always packing packing essential food items for life on the road. I figure, if you can cover a healthy breakfast, lunch and snacks, you can almost always find the time and the place for a decent evening meal.
When I head out on a trip, at minimum I always carry with me, tea bags and sweetener, low sugar instant oatmeal, cream of wheat, protein and /or meal replacement bars, almonds or peanuts and microwavable Healthy Choice soups. It is also a good idea to pack an inexpensive electric boiler pot in case you don't have access to a microwave. My little food bin assures me that I will never go hungry while I'm traveling and can eat healthy throughout at least 75% of my day!
