This is where I part company with the consensus forming above. I think this board over-worries about lean mass. Some lean loss is obligatory — you need less muscle to move a smaller body, and preserving mass you no longer need is not a health outcome. The question is whether strength and function held, and mine did.
Ask again with the specifics and you will get a better answer than this one.

My endo's protocol for lean mass plateau: if weight loss stalls for 6+ weeks at current dose, we go through this checklist before titrating up:
- Food diary review — is intake creeping up?
- Protein check — minimum 100g/day
- Activity audit — steps + resistance training
- Sleep quality — poor sleep kills GLP-1 efficacy
- Stress/cortisol management
Only after addressing all of these do we increase the dose. Often fixing one lifestyle factor restarts progress without needing more medication.

Body composition tracking via bioimpedance on lean mass (InBody scan every 3 months):
| Metric | Baseline | Month 3 | Month 6 | Month 9 |
|---|---|---|---|---|
| Skeletal Muscle (lbs) | 71 | 73 | 69 | 75 |
| Body Fat (lbs) | 93 | 85 | 63 | 47 |
| Body Fat % | 43% | 34% | 28% | 22% |
| Visceral Fat (cm²) | 168 | 113 | 88 | 58 |
Note: skeletal muscle mass dipped initially then recovered with consistent resistance training + high protein. The visceral fat reduction is where the metabolic magic happens.

What fraction of loss being lean mass is actually normal, because the numbers quoted here range from 10% to 40% and cannot all be right?
Closing the loop on my own question.
Second scan under matched conditions, six months apart, same time of day: the lean number came back nearly a kilo higher than the panic scan. Strength was up throughout.
