Adding a me-too, because a thread of one person's experience is not much use. Nothing to add that would improve it.

DEXA scan update relevant to lean mass:
Scanned at months 0, 6, and 12. Here are the body comp numbers:
| Baseline | Month 6 | Month 12 | |
|---|---|---|---|
| Total mass | 251 lbs | 236 lbs | 218 lbs |
| Fat mass | 121 lbs | 71 lbs | 53 lbs |
| Lean mass | 159 lbs | 146 lbs | 155 lbs |
| Body fat % | 44% | 32% | 22% |
Lean mass preserved — actually GAINED 1-2 lbs thanks to progressive overload + 1.6g/kg protein. The lean mass discussion needs to include body comp data, not just scale weight.

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 | 67 | 69 | 75 |
| Body Fat (lbs) | 95 | 85 | 57 | 41 |
| Body Fat % | 43% | 31% | 26% | 22% |
| Visceral Fat (cm²) | 150 | 115 | 85 | 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.

Saving this. It is the first explanation that did not require me to already understand it. Printing the relevant bit and taking it with me.
