Abstract
Abstract
Introduction: The ketogenic diet, characterized by a high-fat, low-carbohydrate, and adequate-protein intake, has gained popularity in recent years as a potential strategy for enhancing athletic performance. This systematic review aims to evaluate the effects of the ketogenic diet on various aspects of athletic performance, including endurance, strength, and overall physical performance.
Methods: A comprehensive search of electronic databases was conducted to identify relevant studies published between January 2000 and December 2022. Studies were included if they investigated the effects of a ketogenic diet on athletic performance in healthy adult athletes. The methodological quality of the included studies was assessed using established guidelines. The review identified 15 studies that met the inclusion criteria, comprising a total of 500 participants. The studies examined a range of athletic activities, including endurance sports such as running, cycling, and swimming, as well as strength-based activities like weightlifting.
Results: The findings suggest that the ketogenic diet may have some positive effects on athletic performance, particularly in endurance activities. Several studies reported improved endurance performance and increased fat oxidation in individuals following a ketogenic diet. However, the effects on strength and power-based activities were less consistent, with some studies reporting no significant differences compared to a higher carbohydrate diet. Additionally, the review highlights potential limitations and challenges associated with adopting a ketogenic diet in an athletic context. These include the adaptation period required for the body to transition into a state of ketosis, potential muscle glycogen depletion, and the impact on anaerobic performance.
Conclusion: This systematic review suggests that a ketogenic diet may have beneficial effects on endurance performance in athletes. However, further research is needed to fully understand the long-term effects, optimal macronutrient composition, and individual variability in response to the ketogenic diet. Athletes considering the adoption of a ketogenic diet should carefully weigh the potential benefits against the challenges and consult with healthcare professionals and sports nutrition experts for personalized guidance.
