5. Not all calories are the same. But what does that mean?

All calories are equal in energy terms. Each gram of carbohydrate has four calories, every gram of protein has four calories, and every gram of fat has nine. That doesn’t change. The term all calories aren’t equal means that some sources of calories are better than others.
