I mean, that is the headline. The thrust of the article was that a lot of the common things people offer for why don't have any real evidence. All we seem to have is that people eat more calories when doing processed foods.

Specifically, the RCT showing that people eating ultra processed foods eat an average of 500 more calories per day is what I was looking at. Seems to basically align far more heavily with it being the volume of food than it is other qualities. Though, my memory was stronger in what that paragraph claimed.
