A umis najit neco o fasting a intermitment fasting?

Je tomu tak kvůli regulaci vstupu glukózy do buněk.After exercise, the restoration of muscle glycogen occurs in a biphasic manner. During the first phase, glycogen synthesis is rapid (12–30 mmol/g wet weight/h), does not require insulin, and lasts 30–40 minutes if glycogen depletion is substantial. The second phase depends on insulin and occurs at a slower rate with euglycemia (2–3 mmol/g wet weight/h), a rate that can be increased to 8–12 mmol/g wet weight/hour with additional carbohydrate intake.

- Feeding: During meals, insulin levels are raised. This allows glucose uptake by tissues such as the muscle or brain for direct use as energy. Excess glucose is stored as glycogen in the liver.
- The post-absorptive phase (six to twenty-four hours after fasting starts): Insulin levels being to fall. The breakdown of glycogen releases glucose for energy. Glycogen stores last for roughly twenty-four hours.
- Gluconeogenesis (twenty-four hours to two days): The liver manufactures new glucose from amino acids and glycerol. In non-diabetic persons, glucose levels fall but stay within the normal range.
- Ketosis (one to three days after fasting starts): The storage form of fat, triglycerides, is broken into the glycerol backbone and three fatty acid chains. Glycerol is used for gluconeogenesis. Fatty acids may be used for directly for energy by many tissues in the body, but not the brain. Ketone bodies, capable of crossing the blood-brain barrier, are produced from fatty acids for use by the brain. Ketones can supply up to 75 percent of the energy used by the brain. The two major types of ketones produced are beta hydroxybutyrate and acetoacetate, which can increase more than seventy-fold during fasting.
- Protein conservation phase (after five days): High levels of growth hormone maintain muscle mass and lean tissues. The energy for maintenance of basal metabolism is almost entirely met by the use of free fatty acids and ketones. Increased norepinephrine (adrenalin) levels prevent the decrease in metabolic rate.
