PLAIN-LANGUAGE SUMMARY

What it found

The main outcome, MRI-measured visceral fat, did not clearly differ between groups. Weight decreased more in the eating-window groups as a secondary outcome.

Keep these limits in view

A short trial with dietary education in every group cannot identify one universally best window. A weight-loss headline does not change the primary outcome.
