IIRC the way calories are measured for food is pretty simplistic, and calories in, calories out isn't terribly accurate. I can imagine it still helps a lot with weight loss, I myself lost ~20lbs a while back counting calories. But like a lot of diets that take some effort to maintain, seems like they probably aren't easy to keep up long term vs. generally eating more healthy and building habits around exercise.
