Your body is made for walking
While you probably do not walk many miles to find food out in the wild today, your body is still equipped to do so. You inherited the ability to walk longer and farther using as few Calories as possible. This ability helped your ancient ancestors survive as they traveled long distances to find their next meal.

Some people walk more efficiently than others. Desert travelers walk long distances to find water. Since they use few Calories, they have enough energy to carry water back home. The speed at which we walk, the size steps we take, and our body shape all affect how we burn calories.
