In this video, Dr. Berg talks about glycogen. Glycogen is the storage of sugar or glucose, glucose molecules strung connected together collectively. When you consume carbs, the body increases insulin and then starts storing glycogen. Then at a certain point, anything extra starts to be converted into fat. Glycogen can store only about 1700 calories. He also talks about what the normal blood sugar is, and how the cortisol activated by stress increases the storage of glucose.

Alright guys, so I wanted to do a quick video on something called glycogen because there are some confusion because it sounds like glucose, glucagon and all these other similar terms. So we have glycogen is basically the storage of sugar. It is the storage of glucose. We have glucose molecules all strung together connected collectively is called glycogen. Now to store glycogen you need potassium, and this is why if someone is in the low potassium diet, they don’t store glycogen as well. So what happens when you actually consume carbs, your body increases insulin and then it starts storing glycogen as the first thing that it does. And then at a certain point, anything that is extra starts to routed in fat. It converts the carbs into fat because we really only have a small amount of storage of glycogen, about 1700 calories roughly about a day supply and then we ran out and the our body is supposed to tap into fat. So then the question is, what is the normal blood sugars and what is too much, and when do you start to go from storing glycogen to storing fat. Well, normal blood sugars is about 80 so that basically means, out all of your blood about a gallon and a third, it is only really 1 teaspoon of sugar. It is very very small amounts. And you can get that sugar from the conversion of fat into sugar, or protein into sugar. So we don’t need sugar to actually make glycogen, your body can make it. Also just FYI, like the cortisol hormone activated by stress will also increase the storage of glucose. In the liver, they will start making sugar out of protein and make more glucose if you need some especially during the stress state. Now out of this total amount of glycogen, the muscle is pretty much holds about 75% of glycogen and the brain has not have a glycogen reserve, it doesn’t store sugar. It gets its fuel from the blood. So whatever is happening in the blood whether there is a low blood sugar or high sugar, it will pull from that. But the point is that the body doesn’t store it. It gets it from other places, but the brain loves to run on ketones. Now, in a little bit of sugar. But again that sugar can be made in a lot of other things and it doesn’t have to come from sugar. But it loves sugar and same thing with the heart, the heart loves ketones as a fuel rather than glucose but it also loves fatty acids. So it can run on few things and it doesn’t have to run on glucose. There is just a couple parts of the body that do need some glucose, but again your body can make it through something called gluconeogenesis the formation of new sugar.
