I'm a stoveless backpacker. I do add in carbs on my trips, because its just easier to get the required calories. For breakfast its usually some Starbucks Via cold, and a Probar. Superfruit Slam or Superberries and Greens. I snack during the day instead of having a set lunch time. Trail mix/GORP, larabars, jerky, dried fruit, etc. Dinner is salami or pepperoni and hard cheese, almond butter and jelly on a whole wheat bagel or tortilla, dehydrated beans and rice with fritos on tortilla, more jerky and cheese, etc. If you have a dehydrator, you can make your own sweet potato bark and add some dried meat. Also check out Packit Gourmet. They sell gluten free meals that are amazing, and many can be rehydrated with cold water. I don't miss a hot meal at all. If its cold I can be bundled up in my sleeping bag, munching on food instead of sitting out in the cold waiting on water to boil. And if its hot, I don't want hot mush anyway. Oh, and never forget the power of a Snickers bar!!! Walking 20 miles a day burns an amazing amount of calories and its hard to beat the calorie per ounce and yummy factor of Snickers. Its not healthy, its not Primal, but it sure hits the spot!
