OMG yes. lean mass + resistance training is the combo. Can confirm.
RegAffairsDC said:Right, and protein targets should be set on a reference weight rather than current weight.
That reframing is the part I needed.

Body composition tracking via bioimpedance on lean mass (InBody scan every 3 months):
| Metric | Baseline | Month 3 | Month 6 | Month 9 |
|---|---|---|---|---|
| Skeletal Muscle (lbs) | 73 | 71 | 72 | 71 |
| Body Fat (lbs) | 100 | 75 | 53 | 45 |
| Body Fat % | 39% | 31% | 26% | 21% |
| Visceral Fat (cm²) | 170 | 115 | 90 | 60 |
Note: skeletal muscle mass dipped initially then recovered with consistent resistance training + high protein. The visceral fat reduction is where the metabolic magic happens.

Bone density monitoring on lean mass: DEXA bone density at baseline and month 12.
Lumbar spine T-score: -0.9 → -0.9 (stable to slightly improved)
Femoral neck T-score: -0.14 → -0.10 (stable)
No significant bone loss despite 61 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.
