Impact of a 6-week non-energy-restricted ketogenic diet on physical fitness, body composition, biochemical parameters and gut microbiome in healthy adults

In this study, the impact of a 6-week isocaloric ketogenic diet in healthy adults on physical performance, body composition, blood parameters and the gut microbiota was examined. The study was designed as single arm, before-and-after comparison study. Physical performance and measurements of body composition were performed and blood and fecal samples before and after the intervention collected and of the latter, 16S rRNA amplicon sequencing performed.
