Is all cheese fattening? No. There are many cheeses with lower fat contents, e.g. Brie has a fat content 1/3 less than cheddar and fromage frais is 1/3 less than Brie. Unfortunately, because cheese is known to be high in fat, it tends to be one of the first things we cut out or cut down on, yet many people find that there is little change in their weight. Why? Because cheese rarely accounts for more than a small percentage of the actual fat eaten in a person's diet.
Instead look for the hidden fats in your diet - bread, muesli, crisps, chips, pastries and biscuits.
