Two Different Dietary Approaches in Body Composition

Time-restricted feeding (TRF) is a dietary approach that includes a fasting protocol and a fasting period ranging from 3 to 21 hours during the day . Since there is no standard definition of TRF, fasting/feeding periods vary. In this study, 12-hour fasting and 12-hour feeding period defined by Pureza et al.(11) were taken as the TRF model. In the first 4-week arm of the study, applied a time-restricted feeding program from sunrise to sunset. The daily energy requirements of the participants were calculated individually to lose 5% of their initial weight and the distributions of macronutrients were 45-60% of total energy from carbohydrates, 10-20% as protein and less than 35% from fat.

Extended-time feeding program was suggested that allows them to eat at any time of the day. During dietary interventions, a weight loss diet was applied to the participants. The daily energy requirements of the participants were calculated individually to lose 5% of their initial weight and the distributions of macronutrients were 45-60% of total energy from carbohydrates, 10-20% as protein and less than 35% from fat.
