Well, you ate it, and that's the end of it! Now you move on. Probably you did learn that it's not as fun as it used to be. And hopefully, you won't be "triggered" into wanting to eat more.
As for what I think about it, two words: Everything counts.
It counts whether
you count it, weigh it, measure it, and calculate the calories--or not. It counts whether it's a dish of ice cream or a tub. Your body doesn't care whether you think you deserve it, whether you're having a hard day, whether it's Thanksgiving, etc. It just does what it does best! If you eat more than you burn, the excess gets stored as fat for later. Voila!
I eat what I want, but I pay attention. I know that some foods aren't worth it, even if I like them a lot, because it leads to my wanting to eat more of them, and more, and... So, those foods are under heavy restriction.
Today I went for a mile walk at the mall. My friend wanted to stop and get frozen yogurt at this "by the ounce" place at the food court. This was perfect for me. My fat-free frozen yogurt with some strawberries, a spoon of chopped peanuts, and a drizzle of caramel topping came to 150 calories. Tasted great. It was all I needed to be satisfied. And, it was limited! I didn't have a whole carton of the stuff sitting in my freezer.
After awhile, you learn how to judge these things. You don't have to be exact to know when you're within bounds.
Even when I indulge, I pay attention.
