A loaf of bread covered in butter is "perfectly healthy" if it satisfies your macronutrient requirements without going well beyond what your body is going to use. But that doesn't fit in with the average person's diet. Eating a 1200 calorie burger (that's high in fat) if your body burns 2000 calories a day likely isn't a healthy choice for most folks who aren't tracking what they eat, especially if they do it regularly.
