Thought diet: the ketone diet reduces the performance of anaerobic athletes
Athletes who turn to dietary diets to help with their performance in low-intensity sports may want to think again, according to new research from the University of St. Louis.
In a small study, Edward Weiss, Ph.D., associate professor of nutrition and dietetics at the University of St. Louis, along with graduate students SLU, RD and Morgan Trott, RD, examining the performance of 16-man exercise and a woman after following either the low-carbohydrate or high-carb diet for four days. His team then tested anaerobic exercises for the participants.
The team discovered that after the ketone diet, the participants did not perform well on exercise tasks.
“In popular discussions, the term ketone is often used as a broader term for systems with low carbohydrate content, including Atkins,” Weiss said. “However, this language is often confused People often think that carbohydrates are low and proteins are high This is linked, but it is different because the protein can only be at the natural levels of a real diet of ketones .
“The goal of the ketone diet is to starve the body of carbohydrates.If there is a large amount of protein in the diet, we will use the body’s protein to make carbohydrates, beating the target.When the body is deprived of enough carbohydrates, which makes the bodies of ketones as alternative fuel, is The emergency backup system allows us to survive when we are in danger of dying of hunger, but it has side effects.
“Now in the general public, they are described for weight loss.Some studies have shown that it is effective for weight loss.But I am concerned, however, this can be a lot of smoke and mirrors. it’s 60% of carbohydrates, so if you restrict carbohydrates you may not eat that much, if you eliminate most of the options for eating, you can lose weight because it reduces calories. ”
The study has implications for those who switch to a diet to lose weight and for athletes seeking to improve their performance.
“The system of affected energy metabolism is anaerobic.” Watching the Olympic Games jump 100 meters triple jump will depend on this system.You can say that this is not related to me.But for someone who has a low aptitude, using this same metabolism to get the stairs, all People use this kind of metabolism without realizing it, and this study shows that this energy system is at risk because of this type of diet. ”
Weiss has a warning.
“There are groups of people who can benefit from the ketone diet,” Weiss said. “For example, patients with epilepsy benefit from this diet.For those who suffer from abnormal cell metabolism that causes seizures, making the cells that feed on the ketones may be useful.”
“Low-carbohydrate, short-term diets and diets with ketones reduce exercise performance in activities that rely heavily on anaerobic energy systems,” says Weiss. “These results have clear performance effects for athletes, especially for short-duration activities and high-intensity sports.
“This diet is particularly hot among people who are trying to improve their health.” What this study says is that unless there are good reasons to follow a low-carbohydrate diet, athletes are advised to avoid these diets. “
