Effects of eight weeks of time-restricted feeding (16/8) on basal metabolism, maximal strength, body composition, inflammation, and cardiovascular risk factors in resistance-trained males.

What was studied

This randomized study tested whether an eight-hour daily eating window changes body composition, strength, metabolism and biomarkers during resistance training.

Who / model studied

Thirty-four resistance-trained men were randomized equally to time-restricted feeding or a normal meal schedule.

Studied dose & schedule

For eight weeks, both groups completed three weekly resistance sessions and ate similar calories and macros; TRF ate at 1, 4 and 8 p.m., while controls ate at 8 a.m., 1 and 8 p.m.

What the study found

TRF reduced fat mass versus the normal diet while both groups maintained fat-free mass, estimated arm and thigh muscle area, maximal strength and resting energy expenditure. Testosterone and IGF-1 decreased in TRF.

Limitations & context

The short study included only experienced, steroid-free men, so it does not establish longer-term effects or generalize to women, novices or enhanced athletes.
