I really don't like FF cheese. I agree with the other posters - eat less of a cheese that will satisfy you. I like low fat string, Laughing Cow, and a few 2% cheddars. I usually buy good deli cheeses (hard, flavorful ones) and use a grinder to shred them. I get a lot of flavor for very few calories
And - I disagree with the comment that full fat cheese is unhealthy. As a vegetarian, I incorporate cheese in my diet quite often. Moderation is the key.
