People who follow a low-carbohydrate diet long-term experience normal energy levels and can perform daily activities without consuming carbohydrates.
Trained athletes on low-carbohydrate or ketogenic diets have lower blood lactate levels during high-intensity exercise compared to those on higher-carbohydrate diets, due to reduced breakdown of muscle glycogen.
Trained athletes performing repeated sprints show a measurable reduction in performance when following low-carbohydrate or ketogenic diets, linked to lower muscle glycogen levels that limit ATP production through glycolysis.
Trained athletes who follow low-carbohydrate or ketogenic diets maintain or slightly increase their performance in short, high-intensity efforts like sprinting or heavy lifting, based on measurements of peak power and strength, because their bodies rely more on phosphocreatine than on sugar breakdown for energy.
During high-intensity exercise on a low-carbohydrate diet, lower blood lactate levels occur because muscles have less glycogen to break down for energy, and this does not mean the body is using energy more efficiently—it reduces the ability to maintain high-intensity effort.
