Sarcopenia is a diagnosis registered in the ICD-10 (code M62.84) characterized by the progressive loss of skeletal muscle mass and strength. Muscle tissue is the largest endocrine organ, secreting myokines, utilizing up to 80% of blood glucose, and regulating bone mineral density according to Wolff's law. With age, anabolic resistance develops, in which the mTOR signaling pathway requires an increased single dose of leucine to trigger protein synthesis. A combination of proper protein portioning, a strength signal of 6-8 intensity, cortisol control, and deep sleep structure helps reduce the risk of falls, maintain insulin sensitivity, and maintain independence in older age.
