Bookmarking. The distinction being drawn above is the one nobody else makes. Adding it to my notes with a link back to this thread.
From the other side of the consultation, briefly.
DEXA scan update relevant to protein intake:
Scanned at months 0, 6, and 12. Here are the body comp numbers:
| Baseline | Month 6 | Month 12 | |
|---|---|---|---|
| Total mass | 276 lbs | 241 lbs | 203 lbs |
| Fat mass | 106 lbs | 76 lbs | 53 lbs |
| Lean mass | 159 lbs | 155 lbs | 150 lbs |
| Body fat % | 45% | 35% | 22% |
Lean mass preserved — actually GAINED 1-2 lbs thanks to progressive overload + 1.6g/kg protein. The protein intake discussion needs to include body comp data, not just scale weight.

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. I would add the less popular caveat: these trial populations under-represented several groups, older adults and the highest BMI categories among them. The results probably generalise, and "probably" should be stated as an assumption rather than dropped.
