Broken valley principle

Within one day of fasting, the glycogen stored in the liver has been exhausted. Because red blood cells and brain tissues usually only burn glucose, the human body began to convert other energy substances into sugar to meet the needs. After fasting for 36 hours, amino acids are released from muscle protein spots, and alanine is absorbed by the liver to make sugar under the action of hormones. After fasting for 48 hours, the body began to mobilize a lot of fat to produce energy.

Fat is not "clean energy". In the process of eating, a large number of acidic products will be produced, and the ketone body content in blood and urine will increase rapidly, and the acid-base balance of body fluids will be tested. At this time, hunger has not been lifted, fat burning can not meet the needs of life, and the human body has to decompose protein in large quantities.
