However, the impact of this form of dieting relative to a traditional high carbohydrate diet has not yet been investigated in resistance trained athletes. PURPOSE: Therefore the purpose of this study was to investigate the impact of VLCKD verses a traditional wes- tern diet on changes in muscle and fat mass. Methods Twenty-six college aged resistance trained men volun- teered to participate in this study and were divided into VLCKD (5 % CHO, 75 % Fat, 20 % Pro) or a traditional western diet (55 % CHO, 25 % fat, 20 % pro). All subjects participated in a periodized resistance-training program three times per week. Body fat and lean mass were deter- mined via dual xray absorptiometry (DXA), while muscle mass was determined via ultrasonography analysis of the quadriceps. All measures were taken at week 0 and 11. Consent to publish the results was obtained from all participants. Results Lean body mass increased to a greater extent in the VLCKD (4.3 ± 1.7 kgs ) as compared to the traditional group (2.2 kg ± 1.7). Ultrasound determined muscle mass increased to a greater extent in the VLCKD group (0.4 ± 0.25 cm) as compared to the traditional western group (0.19 ± 0.26 cm). Finally fat mass decreased to a greater extent in the VLCKD group (-2.2 kg ± 1.2 kg) as compared to the (- 1.5 ± 1.6 kg). Conclusions These results indicate that VLCKD may have more favor- able changes in LBM, muscle mass, and body fatness as compared to a traditional western diet in resistance trained males.
