http://www.livestron...ed-to-body-fat/Although protein offers a number of health benefits, more does not equal better. If you eat more calories than your body needs from protein sources, the excess is converted to fat, albeit in a roundabout way. Protein is first metabolized into amino acids and ammonia. The leftover carbon compound is converted into glucose, which your body uses for energy. If your cells have enough glucose, and there is no space left to store it as glycogen in your muscles or liver, the excess glucose is converted into fat and stored.
