Snack regularly while hiking. I keep bars, dried fruit, or other snacks within reach, in the pockets of my pants or my pack’s hip-belt. Hunger is a delayed signal – it arrives only after your body’s energy reserves have become depleted. That’s not a problem when you’re lying on the couch, but if you’re walking for miles, nibble frequently to avoid letting your gas tank run low. If you notice companions – especially kids, who lack the fat reserves of adults – slowing down, getting quiet or grumpy, or with a faraway look in their eyes, that’s usually a sign they need some food.
