Pork Tenderloin: The Leanest Choice
When it comes to selecting a low-fat cut of pork, the tenderloin stands out as the clear winner. Located along the backbone, this long, narrow muscle is naturally very lean with minimal marbling and no bone. A 3-ounce cooked serving of pork tenderloin contains only about 3 grams of total fat and 120 calories, making it a rival to skinless chicken breast. Its delicate texture and mild flavor also make it a versatile ingredient that pairs well with a variety of seasonings and sauces.
How to Cook Pork Tenderloin Properly
Because of its low-fat content, pork tenderloin can dry out easily if overcooked. For optimal flavor and juiciness, it's best suited for quick-cooking methods such as:
- Pan-searing: Brown the tenderloin in a hot skillet before finishing it in the oven.
- Grilling: A quick sear on a grill over medium-high heat is ideal.
- Roasting: Cook in the oven at a high temperature for a short period.
- Sautéing: Thin medallions cook quickly in a pan, perfect for stir-fries.
Using a meat thermometer to ensure the internal temperature reaches 145°F and then allowing it to rest for a few minutes is the best way to maintain its tender, moist texture.
Other Lean Pork Cuts
While tenderloin is the leanest, several other cuts are also good low-fat choices, particularly if the visible fat is trimmed off.
- Pork Loin: Not to be confused with tenderloin, the loin is a wider, flatter cut from the back of the pig. While it may have a layer of fat (the fat cap), boneless loin roasts and chops are still considered lean options after trimming. A 3-ounce cooked serving of boneless top loin roast has around 5.3 grams of fat, while a boneless loin chop contains about 6.2 grams.
- Boneless Ham (Extra Lean): This cured cut can also be a lean option, with a 3-ounce serving providing about 4.7 grams of fat. It's a great choice for sandwiches or sliced for meals.
- Canadian-Style Bacon: This is made from the pork loin and is very lean. A 2-ounce serving has just 3.9 grams of fat.

Tips for Cooking and Selecting Lean Pork
- Check the Label: Look for packaging that specifies “loin” or “tenderloin” rather than fattier cuts like belly or ribs. Many pre-packaged lean pork products also carry health-related certifications or ratings.
- Trim the Fat: Before cooking, take a moment to trim any visible fat from the edges of the meat. This is particularly important for cuts like pork loin with a thick fat cap.
- Cook at Proper Temperature: Overcooking lean cuts is the easiest way to make them dry and tough. A meat thermometer is your best friend. For whole muscle cuts like tenderloin and loin, the USDA recommends cooking to an internal temperature of 145°F, followed by a 3-minute rest.
- Use Marinades and Glazes: Since lean pork has a mild flavor, marinades and glazes are a great way to add moisture and a burst of flavor without adding excess fat.

Conclusion
When seeking the lowest fat option, pork tenderloin is the definitive choice. Its status as an "extra lean" meat with a favorable calorie-to-protein ratio makes it an excellent addition to a healthy diet. However, other cuts, such as boneless pork loin, also offer a good low-fat alternative, especially when trimmed of visible fat. By choosing the right cut and employing proper cooking techniques, you can enjoy a delicious and healthy pork dish that fits your nutritional goals.
