CER alone increases cortisol levels, whereas CER combined with 16/8 TRF does not, suggesting TRF may mitigate the stress response to caloric restriction.
Caloric restriction can raise stress hormones like cortisol, which might hinder muscle retention. If you are doing a diet, adding an eating window might help keep these stress hormones lower than if you just restrict calories without timing constraints.
ModerateSupportsMEDIUM confidence
Cortisol levels increased only in the CER group.
Why this rating
Small sample size, single time-point measurement post-intervention.

Continuous energy restriction (CER) plus 16/8 time-restricted feeding improve body composition and metabolic parameters in overweight and obese, but no more than CER alone
