I know that last statement isn't anything groundbreaking, but if you can get through the initial hunger created by changing your eating schedule, it can be hugely beneficial to limiting your caloric intake.
It is overall caloric intake. This link [1] has 20 studies cited that support this hypothesis. At the same time, I'm not aware of any clinically controlled studies that contradict this hypothesis.
The doubt always comes from the studies where caloric intake is assessed by questionnaires and self reporting, which in turn was shown to be very inaccurate, i.e. [2].

This seems logical, but like all nutrition-related things, there's an obvious counter argument, and no good science to tell you which is correct.
Obviously I think the study is asking too high-level a question, and barely skimming the surface of how things work. Feels like the same sort of thinking that produced the alternative finding.
