answer:Depends on portion and ingredients. If you eat a one-ounce cube of hard cheese, you ingest fewer calories than if you scarfed ½ a pound. Salad loaded with bacon, dressing, croutons, cheese and salt is a different ketttle of fish from salad dressed in vinegar and herbs. A sliver of cake is different from eating half of it. Some of the double bacon-cheese burgers with mayo dressing at the fast food chains will sink you like a ship. The exact amount of calories does vary.
