Bill had 70 DEXA scans between 2021 and 2026, most of them two to six weeks apart from mid-2023 on. Each measures fat, lean tissue and bone, region by region. The question is what actually changed, and by more than the scanner's own scan-to-scan wobble. The results page also answers questions typed in plain English, like “my left leg's lean mass since 2023”.
