Clinical Trial Summary

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

Description:

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.
