High-fat, low-carbohydrate (LCHF) diets, including ketogenic diets, have gained popularity among athletes for their potential benefits in enhancing endurance performance and body composition. However, the effects of these diets on various aspects of athletic performance remain a topic of debate.
Enhanced Fat Oxidation and Endurance Performance
Body Composition Improvements
Glycemic Control and Metabolic Health
Challenges in High-Intensity Performance
Mixed Effects on Aerobic Capacity
Potential for Central Fatigue
LCHF diets offer several benefits for athletes, including enhanced fat oxidation, improved body composition, and better glycemic control. These advantages can be particularly useful for endurance events and weight-sensitive sports. However, the diets may impair high-intensity exercise performance and increase the risk of central fatigue. Athletes considering LCHF diets should weigh these benefits and challenges based on their specific performance goals and event characteristics.
