Nutrition

Before a slice of soft white bread ever reaches a plate, in the picture most of us carry, a factory has already done part of the digesting, milling the grain to powder and leaving the stomach an easy job. A seeded loaf arrives with all that work still inside. You take that picture one step further, to a body that must burn more calories digesting whole foods, since all of that work is left to it. You have even heard what the extra comes to, in posts and articles and from at least one coach, and it keeps coming back as roughly twice as many calories.
