1. Introduction
In this paper, the article by Vargas et al. (2018), which explores the effect of ketogenic
diet on the body composition of trained men, will be critically evaluated. With the aid of a
randomized controlled trial, the authors in the given study aimed to extensively explore the
consequences on body composition after engaging in an exercise protocol of resistance training
coupled with energy surplus upon consumption of a ketogenic diet for a period of 8 weeks.
Ketogenic diets, with their characteristic dietary principles of comprising of a negligible amounts
of carbohydrate and high amounts of fat, have been the traditional therapeutic diets of choice for
the treatment of seizures in children suffering from epilepsy. At present, limited evidence
highlights in detail on the true effects of ketogenic diet on altering the body composition among
trained individuals, when coupled with a regimen of resistance training. Hence, gaining insights
on the association between body composition, ketogenic diet and resistance training form the
underlying rationale behind selection of this article (Hall et al., 2016).
2. Evaluation of Introduction
2.1. Literature Review
Upon evaluation of the article by Varagas et al. (2018), it can be observed that an
extensive list of references have been incorporated which includes a large variety of 56
references. Further relevant information from the references have been incorporated throughout
the paper as observed in the authors inclusion of ample in text citations in the background,
methodology, results and most importantly in the major section of the discussion. An extensive
list of references incorporated throughout every section of the paper is a major strength of this
