Road Trip Eating tips and snacks

Road trips, while not the ideal eating situation, are definitely doable. If you're planning on stopping to eat at fast food restaurants or any restaurants, you can pretty much find the nutritional info for any restaurant on earth, either on MFP or elsewhere on the internet. It might be good to have a laptop or smart phone on hand to look up the info so you don't have to go as far as planning your route and what stops you'll make before you leave. I have a restaurant nutrition app on my iPhone. There are good choices wherever you eat, you just have to be prepared before you go and don't be afraid to order the food differently from how it's listed on the menu (no cheese, no mayo, etc.).
As far as gas station snacks, obviously your drink choices are going to be water or diet soda. As far as food, unless it's a gas station with made-to-order food like Sheetz, you're pretty much going to have to rely on portion control until you can get to a restaurant. When I'm forced to eat gas station fare, I usually opt for the packaged nuts like pistachios, almonds, etc. Although healthy and a good source of protein, these are VERY high in fat and calories so be sure to monitor your portions.
Long story short: research, be informed, practice portion control. And have fun on your trip!!

Stock up on snacks before you leave. Apples, granola bars (or FiberOne, because I don't know about you but that becomes a problem for me on a long car ride), baked chips, nuts and dried fruit. Many fruits and veggies don't actually have to be refrigerated. Pack diet soda, water, and carbonated flavored water. And, if you have room, you can bring a small lunch bag with you for cold stuff like string cheese or drinkable yogurts. Also, bring some sugar-free gum to chew on when you get the craving to snack out of boredom.
Definately pre-plan your meals for where ever you stop to eat!

I'm currently on tour with a show and am trapped in a car traveling for hours! I agree with all of the above advice. Nutrition information for most fast food/chain restaurants is available - make the smartest choices you can at these places (grilled instead of fried, no mayo/cheese, watch sodium) and stick to water to drink. Lots of fruit is portable (apples, oranges, bananas, grapes, etc). Nuts are good, but watch your portions! I like the 100-calorie almond packs, or I'll portion them out into little baggies. String cheese is good for some protein. You could boil some eggs, bring them in a cooler and peel them when you need some protein (if you can stand the smell). Good luck - you can dooooo it!

I'm glad you asked the question because I'm looking for ideas too! In a few weeks I'm driving from CA to MI and it's 3.5 days in the car and hotels. It's a regular trip for me and in the past, I found that a cooler was helpful and filling it with ice kept everything cold. I would just take a ziploc and fill it with ice from the hotel machine and refresh it each morning.

Some things I took were yogurt, bags of baby carrots and precut apples, nuts, string cheese, single serving cottage cheese, hardboiled eggs, etc. I have the added fun of two big dogs going with me, so I can't really go sit in a restaurant.

Remember to watch how much you are eating. It's long and boring for the most part and eating seems like a good way to pass the time or a good reason to stop, but remember how little you are moving around.

Oh, and beware the Cracker Barrel... Calorie conscious their menu is not.
