                                According to the USDA, higher-quality beef grades like Prime and Choice are distinguished by their extensive marbling, which is a key factor behind the common observation: 'why does my steak have so much fat?'. This intramuscular fat, and the amount of fat present, is determined by a combination of genetics, the animal's diet, and the specific cut of meat you've chosen.
