Effects of a Time Restricted Eating Protocol on Resistance Training Men

The study sought to investigate the effects of 16/8 time restricted eating (TRE) with windows of 16 hours of fasting and 8 hours of eating on on body composition, muscle strength, and metabolic factors during resistance training in healthy resistance trained males

About this study

Thirty-four resistance-trained males were randomly assigned to a TRE group or to a control normal pattern group (ND) with a traditional meal pattern. The TRE group consumed 100% of the daily energy needs in an 8-hour time window: from 1PM (post meridiem) to 8:00 PM whilst the ND group consumed 100% of their daily energy needs in 3 meals between 8:00 AM (ante meridiem) and 8:00 PM. During the experimental period, training loads were similar and standardize in the two groups. partecipants were tested before and after 8 weeks of the intervention. Body composition , basal metabolism, performances indexes and blood parameters were measured. After the completition of the first two months of study, subjects were ask to volunteer to continue the intervention for 10 extra months. A total of twenty subjects from, 10 from each group (TRE or ND) continued and completed the second part of the study.

Treatment and study plan

Time restricted eating

Other

TRE subjects consumed 100 % of their energy needs divided into three meals consumed at 1 p.m., 4 p.m. and 8 p.m., and fasted for the remaining 16 h per 24-h period.

Normal Diet

Other

ND group ingested their caloric intake as three meals consumed at 8 a.m., 1 p.m. and 8 p.m.
