Steel Cut Oats = High in Calories?

So I was super excited to eat my steel cut oats and coconut sugar before my workout. Then I looked at the directions on the container, and it takes more than 30 mins to cook. And if you don't babysit it, you've got loogies galore. On top of that, my husband says, "You know those oats have a lot of calories, right?" Lo' and behold, I just made 600 calories worth of oats. 1/4 cup = 150 calories. I could have eaten a McDonald's bacon, egg, and cheese sandwich for 460 calories. I know that the sandwich has other not-so-healthy stuff in it. But...but...what is going on here? Please help me understand.
