So, tying it back to artificial sweeteners, there's a fair bit of research to suggest that consuming them causes you to feel more hungry.

Just the taste something sweet spikes insulin levels[1], and as you said at least some artificial sweeteners don't cause fullness[2] (I am amused that is not the major finding there, heh).

It makes sense, the body releases insulin in expectation of nutrition coming in, but no nutrition comes in, so the end result is feeling hungrier than before.

The real question is, are they still preferable to sugar anyway given the lower caloric value? My experience is yes.
