Studies of elite athletes chronically adapted to low-carbohydrate diets have uncovered one unexpected finding
their extraordinary ability to produce energy at very high rates purely from the oxidation of fat.
I see the increasing use of very low carbohydrate ketogenic diets (VLCKD) in weight control and management, Ketogenic diets may be useful in sports that include weight class divisions and the aim of our study was to investigate the influence of VLCKD on explosive strength performance.
Despite concerns of coaches and doctors about the possible detrimental effects of low carbohydrate diets on athletic performance and the well known importance of carbohydrates, there are no data about VLCKD and strength performance. The undeniable and sudden effect of VLCKD on fat loss may be useful for those athletes who compete in sports based on weight class. Using VLCKD for a relatively short time period (i.e. 30 days) can decrease body weight and body fat without negative effects on strength performance in high level athletes.
