I use butter, regular sour cream and cheese a frequently but in small amounts which, and this is the most important thing, keep me within my daily caloric intake, of which less than 10% can come from saturated fat. Since I love monounsaturates like olive oil and avacados, I combine differt kinds of fats for the flavor and satisfaction without ending up with too much fat in my diet. Some people who see how I use sat fat and say why bother with a smidge? But fats like butter have wonderful flavor, that mouth feel we never quite get with the fakes and a little goes a long way. Still, if you are serious about SB and you want to forgo butter in the induction phase because you it could de-rail your efforts, don't do it. But do consider using it moderately when you get further on. My neighbor has lost about 10 pounds on SB and brings me samples of the foods, mostly proteins, they are cooking and I am impressed with the yumminess.
I have long refused to be a fatphobe. I even eat my husband's cooking and he has a heavy hand. If I can not have to cook on Sundays, I'll chow down on his offerings but knowing how liberal he is with fats, I eat small portions. When he does pasta dishes, he actually gets mad at me when I make myself whole wheat and flax pasta with it's fabulous 6 grams of fiber. But since I have acquired a taste for it, I like it much better than regular pasta although I will eat that too, on occasion. Nothing is forbidden really but I rarely want anything too junky because my diet is balanced. Good luck with your diet! I hope you get the results you desire!
