Measures metabolically active tissue
The “living” cells of the body such as those found in muscle, organs, blood and immune cells. Also includes intracellular water (water contained inside the cells of your body)
Body cell mass contains the metabolically active (living cells) components of the body, including muscle cells, organ cells, blood cells and immune cells. BCM includes the “living” portion of fat cells but not the stored fat lipids and also includes the water inside living cells called intracellular water. The main electrolyte of intracellular water is potassium.
