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 | 71 | 67 | 71 |
| Body Fat (lbs) | 108 | 81 | 53 | 45 |
| Body Fat % | 39% | 34% | 26% | 21% |
| Visceral Fat (cm²) | 158 | 123 | 93 | 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.
One thing that is still open after newstart_MO’s answer:
Was that from a primary source or from a summary of one?

Physical therapist weighing in on lean mass. I work with bariatric and metabolic patients daily.
The resistance training evidence is critical here:
The Lundgren 2024 JAMA paper[1] showed that structured resistance training preserved 73% more lean mass in GLP-1 patients vs medication alone. When discussing lean mass, we MUST include the exercise component.
My minimum prescription: 3x/week compound movements (squat, deadlift, press, row), progressive overload, 7-10K steps/day, and 1.2-1.6g protein/kg/day.

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.
