Ketogenic period
But before entering stable ketosis, there will be a "ketogenic period", during which energy is not converted, so the body will feel very uncomfortable.
Mainly because ordinary people usually eat too much sugar, so the body is only used to use sugar as an energy source, and not used to burn fat.
It takes different time for everyone to fully enter stable Ultra Fast Keto. Ordinary people take about a week, and it may take longer to eat high sugar for a long time.
Entering stable ketosis means that your body's main energy source has become fat and ketone bodies to replace glucose.
It also means that fat has gone through a lot of difficulties and has been successfully broken down and used up.
Note 1: Carbohydrates are collectively referred to as sugars in this article, including starch, such as noodles, rice noodles, bread, and refined sugars, which are sweet sugars. After eating into the body, it will be stored in the blood in the form of glucose, or it will be stored in the muscle and liver as glycogen.
Note 2: Glycogen can only be produced by liver sugar at the lowest time.
In terms of a normal diet, it takes more than 12 hours for liver sugar to be consumed. So normal people can also produce ketone bodies after fasting for a while, but they break power as soon as they eat breakfast. When there is a lot of glycogen, even if there is a lot of free fat ready to be broken down by the liver, ketone bodies are difficult to make. When liver sugar is low enough, ketone bodies are produced quickly. Usually, after the third day of the ketogenic diet, the number of ketone bodies will be determined by the amount of free fat.
Note 3: Ratio of Insulin to Glucagon
With insulin = storage lipase is stimulated, fat cannot be broken down in fat cells. Without insulin plus high catecholamines = fat can be broken down. Breaking down fat is very troublesome and there are many very slow steps. When fat can be broken down, triglycerides in fat cells are broken down into glycerol + three free fatty acids. Free fat adheres to albumin and is transported in the blood to where it is needed to provide energy. If there is sufficient energy in other parts of the body, it will be sent to the liver to be broken down, and ketone bodies will be produced, which will be transported in the blood to the organs needed for energy.
Note 4: The concentration of ketones in the blood of people who eat a mixed diet (starch, vegetables, meat) will be less than 0.5mmol / L, and the blood ketone concentration will be about 0.6 ~ 3mmo / L under a stable ketogenic diet.
