Genuinely useful, thank you. I had the facts and not the framework. Sending this to two other people who asked me the same thing last week.
From the other side of the consultation, briefly.
OMG yes. lean mass + resistance training is the combo. Can confirm.
Dr.Martinez said:Bone density monitoring on lean mass: DEXA bone density at baseline and month 12.
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 | 271 lbs | 226 lbs | 208 lbs |
| Fat mass | 111 lbs | 71 lbs | 43 lbs |
| Lean mass | 149 lbs | 154 lbs | 155 lbs |
| Body fat % | 40% | 34% | 22% |
Lean mass preserved — actually GAINED 1-2 lbs thanks to progressive overload + 1.5g/kg protein. The lean mass discussion needs to include body comp data, not just scale weight.

Muscle fiber type changes during GLP-1-mediated weight loss, relevant to lean mass: preliminary biopsy data suggests that weight loss shifts the skeletal muscle fiber type distribution:
This "metabolic remodeling" of muscle may contribute to improved insulin sensitivity independent of total lean mass changes. The muscle you keep becomes metabolically better, even if there's less of it[1].
