[Data] two DEXA scans a year — lean mass held at 92% while fat mass halved

Data

Posting this because the title is the whole finding — two DEXA scans a year — lean mass held at 92% while fat mass halved — and a number without its method is a rumour.

The numbers the title promised, since a headline without them is worthless: 92%. Everything below is context for those.

Nothing here is a training or nutrition prescription. Targets and programmes are matters for somebody who knows your history and your training background.

Two scans on the same machine 12 months apart. Lean mass held better than I expected and the lifts told the same story for free.

Ask me anything specific. Anything general I will probably get wrong.

Hydration status and fasting state affect the lean mass estimate. Standardising both is the difference between a comparison and a coin toss.

Cosigning that protein gets harder precisely when appetite drops. That is the actual difficulty and it is logistical.

Reminder that nobody here is prescribing training and the sidebar says so.

Small fix — that is fat-free mass, not muscle mass. The scan cannot separate them the way the post assumes.

Agreed — protein and resistance training. Everything else in these threads is a rounding error on those two.

the appetite effect makes eating enough protein a logistics problem
