Energy balance
Time-Restricted Feeding (16/8) does not significantly reduce body fat mass in healthy, normal-weight young men over 4 weeks, despite increasing fat-free mass.
If you are already at a healthy weight, TRF alone may not burn more fat than your normal eating pattern unless you naturally eat fewer calories during the restricted window. Focus on maintaining your training and protein intake; fat loss may not occur without a caloric deficit.
Both conditions were similarly effective in increasing fat-free mass after four weeks of intervention... we were unable to replicate such findings [of fat loss].
Why this rating
Small sample size, short duration, specific population (normal weight).
