I was wrong, diet soda does appear to be psychoactive (or at least substantially alter brain function) beyond placebo, at least if you also eat carbohydrates too soon before/after consuming it:
'Here's the really disturbing part of the study: Using sensitive brain scans, the researchers found that eating carbs and sucralose together changed the part of the brain that controls our metabolism in what appeared to be lasting ways.
"The regulator in the brain that controls how nutrients are being metabolized was changed, not only when the subjects are consuming the drink, but when they were just having another sweet thing or a salty and a savory thing," [...]
[...] the brain was being trained to misinterpret sweetness.
[...] "It implies that it may not only be the sugar or the carbohydrate during the beverage that is being mishandled, but that carbohydrates they were consuming in other meals in the day that is also being mishandled."
The results happened so quickly -- and so dramatically -- that one arm of the study testing adolescents was stopped for ethical reasons.'
