Interestingly (at least it is something I'm still getting used to), I find myself choosing fat over sugar or refined carbs. I'm finding that more fat keeps me more full. I think my diet is probably a little high in fat right now, but I am still shifting my diet around and haven't balanced it all out yet.
I'm vegetarian, and I don't have a ton of dairy, so I don't think my level of dietary fat is really a big issue. I really wish there were more studies about percentage of dietary fat amongst vegetarians and vegans. I don't think you can study meat-eaters and then apply the same results across the board.
I don't drink cow milk, but I use regular soy milk (not reduced fat).
I use full fat cheeses. I used to like ridiculous quantities of cheese on things, and I expected I would really miss that, but somehow I don't.
Not that they come in low-fat versions, but I'm not afraid of having nuts and avocado, and cooking with oil. I do however use less oil than is usually called for in a recipe, but not skimpy either.
I use 2% Greek yogurt. The nonfat was chalky. I'd like to just use the whole version, but haven't been able to bring myself to do that yet!
I was never much for slathering on the mayo, and I can't stand yucky mayo or fake mayo, so I just use the real thing. I just naturally use it infrequently and lightly (always have).
I've recently been having butter again. I haven't figured out what my balance there will be yet
Salad dressings I try to use homemade, and substitute a little broth or water for some of the oil, but it's still not low-fat by any means. I don't think I've ever met a supermarket low-fat dressing that I can stand to put in my mouth. I would seriously usually rather eat my salad dry, and this was true long before I worried about what I was eating. There's some gross stuff out there.
Salt can be hard. Your taste for it does go down as you use it less. But some people have great success with that and others don't. I really think different people have different taste bud genetics. I think if you don't have problems with high blood pressure (and even some who do have high blood pressure are not sensitive to salt) or swelling or other heart / kidney problems, salt probably doesn't need to be the first thing you tackle.
