When glycogen supply is insufficient, do you break down fat or muscle first?

Glycogen is stored in our body's muscles, and when we do someStrength trainingtime, the body willMuscle glycogenas a major energy drainAnd we'll find out if you didn't eat carbs before training.

If you do strength training first, you will lose energy.

And when our body is depleted of glycogen, the liver will give the body some glycogen, then if in a completely quiescent state, liver glycogen.

It will be consumed in about 12 hours. At this point, the body actually starts to break down our fat, and because there is no glycogen to provide energy, it will look for another energy substance.

Then this energy substance is the fat in our body. If it is in the process of fasting, the body breaks down fat by burning our fat。Because in us on an empty stomach.

There will be no glucose from outside the state.

Supplementation, then the blood sugar level in our body will soon start to drop, so our body will start to gradually break down our fat.

So in the fitness world, many people will say that the body will consume protein crazy after fasting, which can be used as an energy substance, but this is all nonsense, because protein cannot be used as a supplement to our body's energy, only fat can make our body decompose and convert into energy to supplement our physical strength.

Therefore, according to these states, when the supply of sugar sources is insufficient in our fasting state, and the liver glycogen tends to be depleted, the body mainly relies on lipolysis as a major energy**. And the breakdown product of a protein is just a gluconeogenesis.

of minor additions.

When the supply of glycogen is insufficient, of course, the fat is broken down first, which provides more energy.

This should break down the fat first, because other energy substances are needed.

When glycogen supply is insufficient, fat is broken down first, and muscle is not so easily broken down.

When the supply of glycogen is insufficient, the fat must be broken down first.

When the supply of glycogen is insufficient, it will give priority to breaking down fat, so you can eat less sugar**.

I think when the supply of glycogen is insufficient, fat is the first to be broken down.

I think it should be broken down first, don't ask me why, I don't know.

In the fasting state, when the liver glycogen tends to be depleted, the body mainly relies on lipolysis as energy** (glyceroneogenesis and direct utilization of fatty acids and ketone bodies), and gluconeogenesis of protein breakdown products is only a secondary supplement.

It is to break down the fat first, because there is more fat in the human body, so people will lose weight.

When glycogen supply is insufficient, fat is the first to be broken down. Through fat mobilization, glucose is formed. As the time of sugar deprivation progresses, protein begins to be broken down, and finally glycogen in the muscles.

Generally speaking, the muscles must be broken down first, and the fat is often retained until the end.

Answer] :d glycogen is broken down in the liver, muscles, and kidneys. Glycogenolysis is customarily referred to as the breakdown of glycogen into glucose in the liver at an advanced age.

The decomposition steps of liver glycogen are: under the action of glycogen phosphorylase, liver glycogen is decomposed into 1 glucose group, and it is sensitized into 1-phosphate glucose. Glucose 1-phosphate is converted into glucose-6-phosphate under the action of glucose phosphate mutase, which is hydrolyzed into glucose by glucose phosphatase, which is released into the blood to replenish blood glucose.

Because there is no glucose phosphatase in muscle tissue, muscle glycogen cannot be broken down into glucose to replenish blood sugar.

First, distinguish between sugar and glycogen. Sugars (compounds) generally refer to carbohydrates, which are the main energy required for all living organisms to maintain life activities**. Glycogen is also known as liver glucose or glycogen, glycogen is mainly found in skeletal muscle (about 2 3 of the glycogen of the whole body) and liver (about 1 3), and most other tissues, such as heart muscle, kidney, brain, etc., also contain a small amount of glycogen.

By definition, sugar refers to the body's stock, and glycogen is the body's inventory. Your statement that exercise consumes glycogen is not accurate, it should be said that no matter what kind of exercise you do, you will consume sugar.

When strenuous exercise depletes the body's sugar reserves, the glycogen in the body continues to convert to sugar for energy, and when the glycogen is used up again, it is a large amount of fat decomposition, ** the energy required by the body, so as to achieve the purpose of fat loss.

Generally, Asians' diet is based on carbohydrates, and not supplementing sugar is to avoid carbohydrate intake as much as possible, and to forcibly change dietary habits, it is best to use the power of dietary fiber to balance the intestines, quit sugar addiction, and develop the habit of not supplementing carbohydrates after exercise.

The reason is as follows: when the body's blood sugar concentration decreases, only liver glycogen can be broken down into glucose and enter the blood to replenish blood sugar.

Because there is no corresponding enzyme in muscle cells, muscle glycogen cannot be hydrolyzed into glucose, generally when the human body is hypoxic, the glucose in the blood is not up, then muscle glycogen will be hydrolyzed into lactic acid for energy.

Answer: Disguise] :d

Glucose-6-phosphatase is a key enzyme in the process of gluconeogenesis, and glucose-6-phosphatase is lacking in muscle glycogen, so the lack of muscle glycogen cannot directly supplement blood glucose.

Answer: Sequence: Dig up the sugar, glycogen, and fat. Analysis: Sugar in the blood is directly oxidized by histiocytes to provide parametry when blood sugar decreases, and hepatic glycogen.

Lipids in the blood are used only when there is no sugar in the blood.

Finally, the protein is broken down. Only when the glucose metabolism pathway is impaired, fat metabolism is used to oxidize fat to provide energy.
