Pork ranges from about 120 to 330 calories per 3-ounce cooked serving, depending entirely on the cut. A lean tenderloin sits at the low end, while fatty spareribs land at the top. That’s a nearly threefold difference from the same animal, so the cut you choose matters far more than the fact that it’s pork.
Calories by Cut: Loin, Shoulder, and Ribs
The USDA standard serving for cooked pork is 3 ounces (84 grams), roughly the size of a deck of cards. Here’s how the major cuts compare at that serving size:
Loin cuts are the leanest options from the pig. Tenderloin comes in at just 120 calories and 3.5 grams of fat per serving. Boneless top loin chops and rib chops both clock in around 160 calories with 7 grams of fat. A sirloin roast is slightly higher at 190 calories and 10 grams of fat. The exception in the loin family is country-style ribs, which jump to 280 calories and 21 grams of fat because they include more marbling and connective tissue.
Shoulder cuts are fattier by nature, since this is a harder-working muscle with more intramuscular fat. A blade steak runs about 190 calories with 11 grams of fat, while shoulder arm chops and blade chops both hit 280 calories with 19 to 20 grams of fat.
Spareribs top the chart at 330 calories and 25 grams of fat per 3-ounce serving. That’s nearly three times the calories of tenderloin for the same weight of meat.
How Trimming Fat Changes the Numbers
Visible fat on the outside of a chop or roast adds meaningful calories. A University of Wisconsin study comparing trimmed and untrimmed pork found that lean-only pork (with external fat removed) contains about 138 calories per 100 grams, while untrimmed pork with the fat left on rises to 175 calories per 100 grams. That’s roughly 27% more calories just from the fat cap. If you’re watching your intake, trimming before or after cooking is one of the simplest ways to cut calories without changing your portion size.
Ground Pork: Lean Ratio Makes All the Difference
Ground pork is sold at various lean-to-fat ratios, and the calorie range is wide. All of the following numbers are per 100 grams of raw meat, based on USDA data:
- 96% lean / 4% fat: 120 calories
- 90% lean / 10% fat: 168 calories
- 85% lean / 15% fat: 208 calories
- 80% lean / 20% fat: 248 calories
- 73% lean / 27% fat: 304 calories
The pattern is straightforward: each additional percentage point of fat adds roughly 8 calories per 100 grams. The most common ground pork at grocery stores tends to fall in the 80/20 to 85/15 range, putting a typical quarter-pound raw patty (113 grams) somewhere between 235 and 280 calories before cooking. Some fat renders out during cooking, so the final calorie count drops slightly depending on your method.
Processed Pork: Bacon, Ham, and Canadian Bacon
Processed pork products vary dramatically in both calories and sodium. For a quick comparison:
- Bacon (1 raw slice, 28g): 110 calories, 10.4g fat, 210mg sodium
- Country-style ham (1 oz, 28g): 55 calories, 2.4g fat, 766mg sodium
- Canadian bacon (3 oz, 85g): 94 calories, 2.2g fat, 638mg sodium
Bacon is calorie-dense because most of its weight is fat. A single raw slice carries 110 calories, and while some of that fat renders out in the pan, a cooked slice still runs about 40 to 50 calories. Canadian bacon is a much leaner option, with only 94 calories in a full 3-ounce serving. Country-style ham is low in calories but extremely high in sodium, packing over 760 milligrams into a single ounce.
How Pork Compares to Chicken
The classic question is whether pork is a reasonable alternative to chicken breast for people watching calories. Per 100 grams, pork loin comes in at about 198 calories with roughly 20 grams of protein. Chicken breast provides 187 calories but packs in significantly more protein at about 33 grams. That means chicken breast delivers about 18 grams of protein per 100 calories, while pork loin delivers about 10 grams per 100 calories.
If your priority is pure protein efficiency, chicken breast wins clearly. But lean pork cuts like tenderloin narrow the gap considerably, and if you’re simply trying to keep a meal under a certain calorie target, a 3-ounce serving of pork tenderloin at 120 calories is competitive with any lean poultry option.
Choosing the Right Cut for Your Goals
If you’re trying to keep calories low, stick to loin cuts, especially tenderloin, boneless top loin chops, and rib chops. These all fall in the 120 to 160 calorie range per serving and stay under 7 grams of fat. For ground pork, look for 90% lean or higher on the label.
If you’re cooking for flavor and tenderness and calories aren’t a primary concern, shoulder cuts and spareribs deliver more fat (which means more richness) but at 190 to 330 calories per serving. Country-style ribs from the loin section split the difference, offering some of that fattier texture at 280 calories.
Cooking method also plays a role. Roasting and broiling let fat drip away from the meat, while braising keeps the meat sitting in its rendered fat. Pan-frying in oil adds external calories that won’t show up in any nutrition database entry for the cut itself. For the most accurate calorie count, weigh your portions after cooking and account for any added fats.
