Protein and Fat. Protein foods, such as meat or beans, are the next things your body metabolizes. The UCSB website says that the average metabolism rate for both is about 12 hours, but your body first uses the protein. Once all of those calories have been used, you begin to metabolize the fats.
If the body is a machine, then food is the fuel. Being more specific, carbohydrates, fat and protein in foods provide energy for body functions and physical activities (see table 1). They, however, do not produce the same amount of energy (see table 2). Fat produces more than two times energy per gram than either carbohydrates or protein. Metabolism in the body converts carbohydrates, protein and fat into energy. Any excess of these nutrients will be stored as fat in the body.
