Figure 1.

During the 8-week intervention period, the 4-h TRF group ate ad libitum (Ad lib) from 3:00–7:00 pm daily (20-h fast). The 6-h TRF group ate ad libitum from 1:00–7:00 pm daily (18-h fast). During the feeding window, there were no restrictions on types or quantities of foods consumed and participants were not required to monitor caloric intake. Controls were instructed to continue their usual diet pattern and did not have any meal timing restrictions.
