Distribution matters less than total but it is not nothing.

DEXA scan update relevant to protein intake:

Scanned at months 0, 6, and 12. Here are the body comp numbers:

BaselineMonth 6Month 12
Total mass264 lbs224 lbs211 lbs
Fat mass114 lbs84 lbs46 lbs
Lean mass152 lbs151 lbs158 lbs
Body fat %41%31%25%

Lean mass preserved — actually GAINED 1-2 lbs thanks to progressive overload + 1.5g/kg protein. The protein intake discussion needs to include body comp data, not just scale weight.

One thing that is still open after pat_auckland’s answer:

Whether the RDA is the wrong reference entirely during rapid weight loss, and what the actual target should be?

Coming at Dr.NateNeph’s question from a different direction. Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.

Reporting back.

Reporting back — setting the target on reference weight rather than current weight turned an impossible number into a boring one.

Agreed on the target, with the caveat that reference weight and current weight are different numbers. Using current weight at the start of a large loss produces a target that is both unachievable and unnecessary.
