Writing this once so I can stop repeating it across threads. It is about mood and mental health, and it is deliberately narrow — everything I am not confident about is marked as such.

What is actually established

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.

The condition it depends on

For anyone with an eating-disorder history this needs a clinician in the loop rather than a forum. The same drug can be therapeutic in binge-eating disorder and actively harmful in a restrictive disorder.

What I am not sure about

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. Practical detail welcome, however dull — the duller the better.

Agreed, with the caveat that "exercise" for someone with mobility limitations is a different set of options, and the standard advice is written as though everyone can walk for an hour.

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. I would be careful about how confidently the flatness reports get attributed. Rapid weight loss, a large deficit and disrupted sleep produce low mood on their own, and separating that from a drug effect is genuinely hard.

Answering the narrow version, because the broad one does not have a single answer. Training does two things here and only one of them is on the scale. It protects lean mass — which is the reason to do it — and it contributes modestly to the deficit, which is the reason people start and then quit when the arithmetic disappoints them. In a deep deficit, resistance work is the priority and high-volume cardio competes with recovery.

Can confirm. Same sequence, different timescale. I had assumed I was the exception until I read this.
