Glycogen from the liver?
I was wondering how Glycogen is produced by the liver? If you are a limited carb diet, solely vegtables, no sugar, fruit, grains, etc... just vegtables. Where does the glycogen come from?
What effects on the body and the muscles does this have. Does this make you more sensitive to insulin?

Glycogen in the liver is produced when you consume fructose. The liver contains an enzyme called fructokinase, when fructose is consumed it is stored as liver glycogen. High amounts can cause insulin resistance. Fructose in large quantities has an overall negative effect on the body. Fructose has little if any effect on the muscle as little if any fructose ever manages to be made into liver glycogen, when there is too much fructose it simply is turned into fat.

So if one is consuming high amounts of fat, protien and carbs from vegtables then gylcogen should be gone using fat for energy?

I have been using a diet as mentioned above sole carb source vegtables. I wanted to see the effects of not having any glycogen in my body. I have been using this for 3 weeks. No carb load. Now is it muscle wasting not to have carbs and using this method. I know my strength is gone.

If your protein intake is adequate, your calorie intake is smart and well placed, then you should be losing minimal muscle with any fat loss. If your looking flat, muscle wise, it's normal, as glyocgen in the muscle is depleted water is removed out of the muscle and leads to a flat appearance.

lack of carbs has a diuretic effect which can make you look more ripped or smaller. but of course your glycogen stores will be decreased and that does make the muscles look smaller and along with the lack of water in the muscle you are going to look horrible.
low carb too long decreases leptin. low levels of leptin = low metabolism. the body's way of responding to your dramatic diet. Carb up every 3-5 days is the best way to solve this problem.
the body can store a crapload of carbs, i think 100 grams in the liver, and 200-400 in the muscles, but of course this is entirely dependent on how much muscle you have. That's why the weekend feedings on the anabolic diet are so carb laden since you assume you start at zero.
either way, be careful of assuming that you can just drop carbs and watch the weight fall off week after week. if that were truly possible, then in theory, if you were at a calorie deficit everyday, then eventually you'd wither away to nothing as your body continues to burn. your body will re-negotiate metabolism and get back to a steady state of neither loss or gain.

Good posts from everyone in here ^_^
Bottom line, you are going to want/need a refeed time, be it once every week, or once every two. You are going to gain a nice chunk of weight(I gain around 5-8 or so lbs on refeeds) But it is usually gone by Tuesday. It also feels pretty sweet when your muscles are full and you just feel like gold
