Does a DEXA repeated every two weeks give me an usable lean-mass trend?

Asked 27 Jul 2024Modified 2.0 years agoViewed 5.1k times
4

I have three DEXA scans on the same scanner at twelve-week intervals, fasted, same time of day.

The comparison I want does not seem to exist anywhere in a form I can evaluate.

I have read the arguments for each and they do not engage with each other.

What does each option buy me, and what does it cost me?
