I like butter

If asked to give up one food it would not be butter. I can't imagine not being able to eat or cook with it, think about butter cream frosting or hollandaise, they would not exist. Yes I know there are good substitutions but to make them the correct way it is not possible. My solution so I can use butter when and where I like is to cut down or eliminate it in ways I will not notice it's absense. Try making mashed potatoes using olive oil in it's place and adding some of the cooking liquid until they are the right consistency. Just like making them with butter and milk you can use the same proportions, you will find that they are light and fluffy and seasoned with salt and pepper taste very good. You could also roast garlic and using more oil than you normally use and add that in place of the olive oil, roasted garlic mashed potatoes don't get any easier to make. I am not a nutritionist or claim to be one and now I can use the butter in some other way.
