The “learning” paradigm is an interesting subset of studies, some of which do show increased weight in rats fed LES vs sugar with a moderately sweetened feed. The authors conclude that there does appear to be an effect here, but the problem is its applicability to humans. The experimental setup is contrived, exposing rats to a food source they are not used to. One hypothesis is that the LES sweetened water may make the food more palatable to the rats, so they consume more.

I suspect that this is more important in humans than he thinks--it might be harder to do these experiments in humans than in rats, and I don't know that it comes down to palatability--but I do know that a big mac and fries with a diet coke would hit the spot--but with water, not as much.
One thing about the learning paradigm--it predicts that sweeteners could be good, bad, or indifferent, depending on how you were exposed to it over time. With food, without food. In place of sugar that you never eat anymore--or replacing sugar sometimes, not others.

This is not quite true, or at least not complete. One study is to feed animals a sugary chow--and the next day, a starchy chow, but with sweetener added so it tastes like the sugary chow. Going back and forth between the two is more fattening than feeding them the one or the other. The same works with potato chips with fake fat the one day, and real fat the next. Is this that unusual an experiment? I remember choking down low fat versions of fatty foods--and then the fatty versions one the weekend, or more frequently, as a treat--as a pretty regular thing, before I went low carb.
