How many calories does pork have?

Pork contains between 225 and 550 calories per 100 grams of meat, depending on the type of cut. The caloric content of any food depends on its serving size and the ratio of protein, carbohydrates and fat that make up the food.

Protein and carbohydrates each contain four calories per gram, whereas fat contains nine calories per gram. Pork is leaner than other kinds of meat, meaning it contains a higher ratio of protein to fat. Leaner cuts of pork, such as the loin, have far fewer calories than cured pork products, such as bacon, for the same amount of meat.
