Efficacy of ketogenic diet on body composition during resistance training in trained men: a randomized controlled trial

Abstract

[...]even though endurance exercise is more effective than RT in reducing VAT [48], a combination of endurance training and RT is more plausible for improving body composition in this population [49].Since few studies have evaluated the combined effect of the KD and RT in trained subjects on VAT, our study contributes to current literature by showing a significant reduction in VAT after 8 weeks of KD in hyperenergetic condition in resistance-trained men.[...]this research only included body composition measurements and did not include blood measures.[...]it is possible to have variations in energy intake even though participants were instructed to follow specific dietary recommendations.[...]since KD may affect negatively training volume, we should consider integrating performance measurements or load volume to see changes.[...]this research showed no significant changes nor effect size on LBM, despite hyperenergetic condition and high protein intake (2.0 g∙kg− 1⋅d− 1) in resistance-trained men of the KD group.[...]we conclude that low-carbohydrate dietary approaches, such as KD, would not be an optimum strategy for building muscle mass in trained men under the training conditions of this study (mechanical tension-focused RT protocol during 8 weeks).
