A 100 g serving of cooked pork tenderloin provides roughly 145 calories and 26 g of protein, per USDA FoodData Central — as lean as chicken breast. Fattier cuts (belly, ribs) are much higher in calories and saturated fat. Tenderloin and loin chops are the lean picks. Trim visible fat and grill, roast, or stir-fry rather than fry.

Key facts:

  • 100 g pork tenderloin: ~145 kcal, ~26 g protein
