Who is advocating that? Not counting is not the same thing as unlimited. Early on, the goal is to get fat adapted (via being in a state of nutritional ketosis). For most, once you reach that state, you can trust satiety signals to guide you, and not count calories.
The only people I’ve heard on this forum that had issues with their satiety signals not working, we’re drinking a lot of artificially sweetened drinks and/or consuming a lot of artificial sweeteners.
The whole debate (I thought) was because I told the OP she might be overdoing the fat. Personally, I have always loved fatty foods and I’m not convinced they’re a great satiety signal for me, at least not at the moment, so I do keep a casual eye on calories. So we’ve been on the same page all along? 

. And not truly eating the butter, she’s bypassed the mouth processes, and hence there’s no brakes from the system saying Whoa! Enough!!
