We are biologically hardwired, aren’t we, to want more food, always more? The failures of our massive efforts in dieting away the pounds or designing an effective drug are proof. Aren’t they? Look again. If anything, the human digestive system is designed to maximize our ability to move, not our ability to take in food.
Think about it. Humans stand upright. As a result of our upright posture, we have a mobility that is rare among animals. We do not hibernate. Our transformation from infant to adult does not involve a cocoon or chrysalis stage. We are constantly moving. We are not the fastest or strongest. We are not the most agile or deft. What characterizes our movement is its novelty: we are constantly learning to make new movements, new patterns of sensing and responding that guide us in thinking, feeling, and acting. As a result of this ability, we have proven ourselves capable of finding food and making ourselves at home in nearly every climate on earth.
At every point, our digestive system enables us in making these movements. Our manner of processing what we consume provides us with a steady stream of energy so that we can keep moving. We do not eat one meal a week and sleep it off like other carnivores. Nor do we spend a third of every day grazing like the large herbivores. Instead we move through recurring cycles of hunger and fullness over a 24-hour period. We stomach small, dense meals, mostly cooked, preferably several a day. These rhythms of digestion allow us time between meals to hunt, gather, and grow food, while still providing us with the steady stream of nourishment we need in order to do so. Even when we are in a position to eat more energy than we are burning, we store it all over the body, in patterns that, until we are extremely obese, maximize our ability to keep moving. We eat to keep moving so that we can eat to keep moving from environment to environment, season to season, continent to continent, meal to meal. And in order to move, we must stop eating.
Further, in making the food-finding movements that our digestive system enables and requires, we have evolved to rely on our sensory awareness as a primary guide. Unlike many of our animal siblings, we can catch and cook, chew and digest almost anything. Our food needs are not determined by instinct or climate. We have to make choices about what to eat, how to acquire it, and when and how to eat it. We have no choice but to choose. While culture and tradition and habit do constrain these choices, the surest guide we ever have is our senses. We are creatures who can and must use all of our senses — taste, smell, touch, sight, hearing — to guide us in identifying, pursuing, and securing what will nourish us and rejecting what will not. The foods we are primed to sense as pleasurable, then, are those that support us in the ongoing project of moving, sensing, and responding to food. Our survival depends upon it.
Gathering the pieces together, this picture is suggestive. The pleasure we derive from food does not come from the quantities of vitamins and minerals, or the salts or sugars present in a chemical substance. The pleasure we seek comes from participating in the process of learning how, when, what, and why to eat so that we can keep moving. The pleasure we seek comes from the experience of finding our way to a sense of enough so that we can stop eating, as we must, and keep moving.
The problem is not that our desires run rampant in the field of abundance; the problem is that we have lost touch with the desires that are and remain our best guide wherever we are. Our dissatisfaction is calling us to tune into our sensory awareness, and to find our way to a sense of enough.
