This gets cited here weekly, usually second-hand, so it is worth setting out what it does and does not establish.
Reduced interest in alcohol is one of the most consistently reported off-target effects, and the mechanism is plausibly the same reward-salience pathway that quiets food noise. The practical part people get wrong is that tolerance changes: less food in the stomach, faster gastric emptying of liquid relative to solids, and a smaller body mean the same two drinks land considerably harder than they used to.
Where I think it is weakest: the population was selected and supported in ways a real cohort is not, so I would read the effect size as a ceiling rather than an expectation.
What I am trying to establish is whether the change in tolerance is the smaller stomach, the smaller body, or something central, and whether it settles. If the honest answer is that nobody knows, that is a useful answer and I would rather have it.
