But now, scientists at the Helmholtz Zentrum München and the Ludwig-Maximilians-University of Munich (LMU) have uncovered in a joint study of a whole metabolic network on multiple levels and the clock for it sits not as suspected in the brain but in the cells of the body. In other words, The muscles have their own internal clock. This 24-hour metabolic rhythm of the muscles, the researchers have focused, for the first time.
