Clinical perspective, offered as context rather than as advice.
Bone density monitoring on lean mass: DEXA bone density at baseline and month 12.
Lumbar spine T-score: -0.8 → -0.8 (stable to slightly improved)
Femoral neck T-score: -0.9 → -0.9 (stable)
No significant bone loss despite 50 lbs of weight loss. Key factors: adequate calcium (1200mg/day), vitamin D (5000 IU/day), resistance training 3x/week, and adequate protein. Weight-bearing exercise is critical for maintaining bone density during rapid weight loss.
Adding the clinical framing, because it changes how the question reads.
Sharing my comprehensive lab data relevant to lean mass:
| Biomarker | Baseline | Month 3 | Month 6 | Month 9 |
|---|---|---|---|---|
| Weight (lbs) | 289 | 259 | 219 | 199 |
| A1C (%) | 7.4 | 6.9 | 6.2 | 5.6 |
| hsCRP (mg/L) | 9.0 | 3.0 | 2.5 | 1.5 |
| Triglycerides | 209 | 169 | 149 | 99 |
Protocol: Tirzepatide 10mg/wk, resistance training 5x/week, protein 1.5g/kg/day.
The improvements in lean mass are clearly reflected in these numbers. The inflammatory marker reduction (hsCRP) is particularly striking.

Adding a me-too, because a thread of one person's experience is not much use. The detail I would add is minor and it is already implied above.

Back pain as a lean mass side effect: not from the medication itself, but from rapid body composition changes. Losing 49 lbs shifts your center of gravity and your core muscles need time to adjust.
Physical therapy has been essential. Core strengthening exercises (planks, dead bugs, bird dogs) daily for 10 minutes have eliminated my lower back pain. Your body is literally relearning how to carry itself.
