I would suggest trying the following things based on my own experience:

Substitute a higher protein / lower fat snack for the things like Macadamia nuts, cheese cake pudding and cream cheese part of the time

Might want to consider using Ranch Dressing instead of Blue Cheese some of the time also

Try mixing sour cream or french onion dip with mayo and using that instead of mayo in noncooked dishes - it cuts the fat and calories and I can't tell much difference in taste (actually, the dip / mayo combo is better in most recipes)
