Dr.ReproEndo said:lean mass + resistance training is the combo.
Regarding lean mass: I accidentally injected my dose intramuscularly instead of subcutaneously last week (went in at wrong angle, too deep). Called my pharmacist — they said it's not dangerous but may absorb faster, potentially causing more GI effects.
Sure enough, had worse nausea that day. Lesson learned: pinch the skin properly and use the right needle length for your body composition.

That reframing is the part I needed. Adding it to my notes with a link back to this thread.
Dr.ReproEndo said:lean mass + resistance training is the combo.
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.

BrianDallas92 said:...the muscle loss concern with lean mass...
This is a legitimate and well-studied concern. Let me put some numbers on it:
In STEP 1, approximately 39% of weight lost was lean mass. However, the Lundgren 2024 study showed that structured resistance training reduced this to ~25% lean mass loss.
Context matters: at BMI 35+, you're carrying excess lean mass to support the extra weight. Losing some lean mass is expected and not inherently harmful if you maintain adequate muscle function through exercise.
The solution isn't avoiding the medication — it's combining it with proper exercise and protein intake.
Moderator note: leaving this open. It is being argued well and the disagreement is the useful part. Report rather than reply if it drifts again.
