The amount of calories in a pork chop varies widely depending on the size of the chop, the cooking method and any added flavorings. A 100-gram serving of pork chop may contain between 100 and 250 calories.
A 100 gram serving of raw, boneless, lean only top loin pork contains 117 calories. A 100 gram serving of broiled, boneless pork loin chop with lean and fat contains about 197 calories. Broiled, lean only, boneless pork chops from the center rib loin contain about 216 calories per 100 grams.
Even a lean-meat only pork chop may contain over 10 grams of fat. Fat supplies about 9 calories per gram. Baking pork chops with additional fat such as oil or butter may significantly raise the calorie count.
