When you eat a meal, your body begins the process of digesting the
food, drawing out the nutrients and processing them to create energy
that keeps your body functioning properly and effectively. It takes
approximately 4 hours just to absorb the nutrients. This is repeated
with every meal you eat. In a day, that amounts to 12 hours that your
body is busy absorbing each meal's nutrients.

In short, during the digestion process, our bodies burn calories. This
is especially true of foods containing carbohydrates and protein which
take longer than other foods to digest. Simply by eating, digesting
and absorbing nutrients from the food, you speed your metabolism.
