I do too as most of it tastes terrible and after several years we find out it is worse for us than the real thing.
When the food producers attempt to fake out fat, usually they produce something that tastes like it came from a test tube.
There are things like fat free raspberry vinaigrette which are pretty darn good. If used on a salad at a meal that will contain other fats, it doesn’t cheat you of anything to use it.
