On a suppressed appetite the winning strategy is protein density per unit of volume, not per calorie.

I will push back on the powder-first advice. It works and it also trains people out of eating food, and when the drug stops the habits are what remain. Getting protein from meals is slower and holds up better afterwards.

One concrete data point for the thread. One habit that pays for itself: post the method alongside the number. A figure without its method cannot be checked, and an unchecked figure is how this community accumulates folklore.

Coming at TirzTom’s question from a different direction. 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.

A narrower follow-up, since the general answer is now clear:

How people are hitting a protein target on a genuinely suppressed appetite, because volume is the binding constraint rather than willingness?

Closing the loop on my own question.

Update: two thirds of the target before midday. Same total, same appetite, and I am hitting it most days now.
