Cheese contains a lot of (yummy) butterfat, but don't go by the labels.
The fat content on the label is based on the percentage of solids in the cheese, not the total weight. Since most cheeses are at least 50% water, you have to consider that, and (rough rule of thumb) cut the percentage shown at least in half. So if you see 45% on the label, it's probably only about 22% overall. Soft cheeses even more so, due to their higher moisture content.
