Short-term time-restricted eating (8-hour window) leads to greater loss of trunk lean mass compared to an extended 12-hour eating window, although total body mass loss is similar.
While your muscle building capacity (MPS) stays the same, you might see a small drop in 'lean mass' on body scans during the first 10 days of an 8-hour eating window. This is likely due to fluid or organ mass changes, not actual muscle loss, especially since your muscle synthesis rates are unchanged. Don't panic if your strength doesn't drop.
Lean mass loss was greater following TRE compared with CON ((cid:4)1.0 (cid:1) 0.7 vs. (cid:4)0.2 (cid:1) 0.5 kg, respectively; p = 0.01).
Why this rating
RCT with DXA scans, but the interpretation of 'lean mass' loss as potentially fluid/organ mass reduces the certainty of it being true muscle loss.
