Glycogen used locally
When I started to practice sports again, I noticed a very big drop of
weight each time I wass changing activity. For instance, When I started to swimm again, I droped 4-5 pounds in 2 days. Same thing when I took up running. I fidured out it could mean that glycogen that was contained in the muscles was used only when the specific muscle was in need of it. And someone had told me it wasn't working that way, and that if you are in ketosis, you have no more glycogen, neither in your lever nor in you muscles. Guess what : I found that it is not true. http://www.uvp5.univ-paris5.fr/CAMPU...ly/0200faq.htm reading this french article about how the body uses carbs, I read this : "A jeun : Afin de maintenir la glycémie à des taux physiologiques optimaux, hors des périodes post-prandiales, les réserves hépatiques en glycogène sont dépolymérisées (glycogénolyse) et du glucose est sécrété dans la circulation. Les réserves musculaires en glycogène sont exclusivement mobilisées in situ sous forme de glucose lors d’un effort musculaire." The last sentence could be translated as follows: Glycogen reserves of a musle are excusively used locally during a muscular effort. I thought it could be interesting to share. Huey |

There will be some small amount, but generally glycogen does get depleted from liver and the muscles -- that's why we LCers get the water weight reduction at the beginning of going LC. Also, that statement doesn't not imply that glycogen won't get depleted, it just said it is used locally within a muscle during effort. |

And someone had told me it wasn't working that way, and that if you are in ketosis, you have no more glycogen, neither in your lever nor in you muscles. That's not true. Ketosis happens when the liver is depleted of glycogen. The muscles have nothing to do with it. |

"DJ Delorie" wrote in That's not true. Ketosis happens when the liver is depleted of glycogen. So, is it possible that the liver holds at least 5 lbs of Glycogen? This might explain why some people gain a quick 5 pounds when they cheat or stop ketosis! |

Cameron,
The refilling of Liver Glycogen is EXACTLY why people will suddenly gain a surprising amount of weight when they boost their carbs, often by a relatively small amount. I will always gain 2 lbs if my carbs go over 70 grams a day and it will always take 3 days for those two pounds to come off. If I boost my carbs over 100 for more than a week, I'll gain 6 lbs--the same 6 pounds I lost when I started low carbing. It's useful to know how much you personally will regain after a carb up to save yourself from the panic that otherwise afflicts many low carbers and, paradoxically, causes them to give up and eat everything in sight just because they regained a couple pounds of water weight. -- Jenny Cut the carbs to respond to my new email address!

This might explain why some people gain a quick 5 pounds when they cheat or stop ketosis! The liver hold much less than 5 lbs of glycogen -- around .5 to l pound of glycogen. But for every gram of glycogen stored 3-4 grams of water is stored along with it. So yes, its really easy for someone can gain back "weight" when they go from LC to eating carbs again due to liver and muscle refilling. -- Rudy - Remove the Z from my address to respond.
