This gets cited here weekly, usually second-hand, so it is worth setting out what it does and does not establish.
The mental-health dimension is under-measured in the trial literature and the reports here are consistent enough to take seriously. On the positive side: reduced anxiety around food, better self-image, more confidence. On the difficult side: grief for the years lost, identity disruption, relationships built around eating, and the loss of food as a coping mechanism with nothing put in its place. Rarer but real: anhedonia and emotional flatness. Regulators have started asking for validated patient-reported outcomes in this class; the existing data gap is not evidence of absence.
Where I think it is weakest: the comparator does most of the work in how this gets reported, and it is not the comparator most people think they are citing.
The narrow version of the question is how people separated a drug effect from the ordinary consequences of a large deficit and disrupted sleep, because I cannot. Happy to be told the question itself is wrong.
