Insulina function
Insulin function The fact that it lowers blood glucose and is released by raising blood glucose linked insulin to glucose metabolism, which is not quite accurate, as its actions go much further. The main function of insulin is to dispose of glucose, that is, to organize mitochondrial and cellular processes, mainly for the production of amino acids, but also for the synthesis of fatty acids and glycogen. In other words, insulin regulates the process of synthesis of glycogen and muscle proteins, which is fundamental for muscle hypertrophy. But it also modulates the formation of triglycerides and its excess increases the accumulation of fat. Therefore, during periods of growth, when there is a greater demand for AA, the role of insulin will be essential. If there is no insulin, there will be no production of IGF-1 and consequently there will be no suppression of the release of growth hormone (GH) by the pituitary gland. The function of GH in this context will be to provide the mobilization of fatty acids, with the aim of stimulating the release of insulin and supplying the tissues with the necessary caloric intake. So, when you sleep, the body produces GH which stimulates the breakdown of fat and provides energy that will help protein synthesis. Adipose and muscle tissue will need insulin to adjust the metabolic machine, aiming at the production of fatty acids and amino acids. This explains why there is no way to gain lean mass without accumulating fat, but if the diet is done well it is possible to gain a ratio of 2kg of lean mass to 0.5kg of fat
