I had the opposite experience. I measured calories everyday and for some time would still eat garbage but lose exactly what I calculated according to my TDEE (adjusted over time based on actual results not some calculator) and when I switched to eating healthful foods experienced exactly the same weight loss with the caveat that it was SO MUCH EASIER. I was hungry less often and felt good rather than terrible with headaches. All in all, a calorie is a calorie is true enough that whether or not its a bad calorie wont significantly affect your weight loss but will make the process much easier and you'll end up healthier as a result of eating well.
