I too am conserned about the Sat Fats... I was at 45 easily a day.
So what I did was buy some Soy Sausage, Soy Veggie Cheese (which is pretty good believe it or not) to cut down on my sats (they have 0 sat fats - gimmee lean brand sausage and Veggie Slices cheese) I also have been cooking with Tofu (firm). One thing I wouldn't recommend to my worst enemy is soy/veggie hot dogs BARF!
If you go to Atkins website, they do recommend Soy products (just watch and read what you pick up, meaning carbs as well as ingred.). Soy's got a lot of good benefits, and its very high in protein
Good luck !!
