Here is the perspective of one bariatric surgeon on how our meal volume progresses over time. In short, after a few years, we will typically be able to eat about half of what we could eat pre-op in a sitting or meal. This is consistent with my experience at seven years out, and my wife's at thirteen years out. There is still enough restriction to aid in effective long term weight control, but also plenty of capacity to go overboard on the wrong foods and see extensive regain. This doc is one of the few that I have seen that discusses this aspect of our surgery, and offers a prescription on how to mitigate the negatives of it. You may or may not get along with his prescription (I don't buy into everything he says....) but he does offer a model that we can use to develop our own approach to long term maintenance and weight control.
