My idea of good “road food” has shifted dramatically in the last few years. It used to mean lots of crunchy snacks and possibly some candy to eat while driving; lunch stops at A&W or Burger King for burgers, fries and floats—the kinds of “treats” I didn’t usually eat at any other time—and some kind of easy camp dinner, usually involving large amounts of processed carbs. And possibly Spam (but that was a REALLY long time ago). Road food was kind of like fair food: you knew it wasn’t good for you, and you might be really sorry later, but it tasted so good that you didn’t care.
Since adopting a clean, whole foods, low-carb way of eating (I won’t call it a “diet”; it’s simply the way I eat), I have experienced such a huge improvement in every area of my health, energy levels and body composition, that I no longer view a road trip as an excuse to eat junk.
