DEXA scan facilities — what worked for you?

lean mass + resistance training is the combo.

Physical therapist weighing in on lean mass. I work with bariatric and metabolic patients daily.

The resistance training evidence is critical here:

The Lundgren 2024 JAMA paper[1] showed that structured resistance training preserved 73% more lean mass in GLP-1 patients vs medication alone. When discussing lean mass, we MUST include the exercise component.

My minimum prescription: 3x/week compound movements (squat, deadlift, press, row), progressive overload, 7-10K steps/day, and 1.2-1.6g protein/kg/day.

Right, and protein targets should be set on a reference weight rather than current weight.

Genuinely useful, thank you. I had the facts and not the framework. Adding it to my notes with a link back to this thread.

Body composition tracking via bioimpedance on lean mass (InBody scan every 3 months):

Note: skeletal muscle mass dipped initially then recovered with consistent resistance training + high protein. The visceral fat reduction is where the metabolic magic happens.

Two DEXA scans eleven months apart: down 24kg total, of which the scan says 6kg was lean.

DEXA scan update relevant to lean mass:

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

Lean mass preserved — actually GAINED 1-2 lbs thanks to progressive overload + 1.6g/kg protein. The lean mass discussion needs to include body comp data, not just scale weight.

Moderator note: the sourcing question belongs in the vendor section and has been split out. Tagging this one for the weekly digest.
