Keep in mind that I'm an "older" woman, and we really do better with lower fat--at least I do, and I've read that's common for some older women.
I eat a lot of fish, and I always poach it in water (it stays nice and moist that way).
I do a lot of meat in my slow cooker with just some water or wine (very little).
I'll broil my hamburgers or steak--or, if I use the frying pan, just a little butter or olive oil to keep it from sticking initially.
I find that my fish (salmon, tuna) and meat has enough fat, and I don't need to add more.
I will use olive oil to dress my salads and veggies.
