Muscle glycogen storage, utilization, and repletion are equivalent between ketogenic and high-carbohydrate ultra-endurance athletes who are keto-adapted.

“the rates of glycogen storage and replenishment were equivalent between the two groups so this is pretty contrary to popular thinking that you know even in the ketogenic athlete you are replenishing glycogen which is pretty wild”

“muscle glycogen stores and repletion appears to be equivalent once you adapted to a ketogenic diet”

“Finney published a paper in 1983 showing that muscle glycogen was cut in half on a ketogenic diet and Finney study was shorter it was a few weeks long but Bullock's keto dieters were also eating four times as much carbohydrate as Phineas were”

“muscle glycogen content in middle millimole per kilogram and then on the and it's 0 to 250 and that both the high carbon low-carb athletes have a range from about 90 to 220 again the highest amount of glycogen is in a low carb athlete they drop with exercise and then within 120 minutes they're come they're all replenished to about I would say about a hundred right and it's it's equivalent between the high carb in the low carb groups”

“I disagree with both Joe and Chris and and James that there is good evidence that in keto adapted athletes we have full glycogen stores and that athletes do not need carbohydrates to perform either explosively or an endurance sports”

“the faster study which is metabolic characteristics of keto adapted ultra endurance runners show this is done by finian bollock and zack bitter was actually a part of them yeah that's interesting yeah and zack bitter was on Joe Rogan's podcast last week he's the current record holder for the 100 mile time and he is a pretty low carb athlete but where they show very clearly in this study is that rates of glycogen utilization and replenishment are equivalent in low carb and ketogenic athletes”

“at least an ultra endurance athletes when they're key to adapted they show that muscle glycogen and storage must with like egde and storage and repletion are equivalent between ketogenic athletes and high carb athletes have you seen this one it's the faster study from Finney and Bullock”

“there is good evidence that in quito adapted athletes we have full glycogen stores and that athletes do not need carbohydrates to perform either explosively or an endurance sports”

“what they show very clearly in this study is that rates of glycogen utilization and replenishment are equivalent in low carb and ketogenic athletes meaning they compared muscle biopsies of high carb athletes and low carb athletes and they were the same”

“if you have full glycogen stores mm-hmm how is the physiology different between high carb and low carb the only question is can you do glycolysis clearly if you're using the glycogen you have the enzymes for glycolysis even though pyruvate dehydrogenase may be down regulated you're not gonna push it into assets he'll go away in the Krebs cycle you are still doing glycolysis and using that fuel you're burning that glycogen and anaerobic metabolism you can still do that even if pdh is down regulated pyruvate the drogyn ace and then they replenish at the same rate as the high carb athletes”
