Ounce for ounce, any type of fat or oil (in its natural form) will contain the same amount of calories. For example, and ounce of olive oil and a ounce of lard has the same number of calories. However, the olive oil is far healthier for you than the lard. Fats and oils will be used in small amounts in low calorie cooking, but choosing certain ones will be healthier for you.
