Why do we have more than 100% when all components added up?
The main components of the chemical structure of human body include fat tissues, water, protein, and inorganic tissues. A fat tissue is mainly comprised of fat and water, wherein water accounts for about 25% of total fat tissues. A muscle tissue is mainly comprised of protein and water, wherein water accounts for about 70% of total muscle tissues.
This body fat scale measures contents of fat tissues, muscle tissues, water, bone, and other major tissues in human body. Due to various tissues containing certain proportions of water, the sum exceeds 100% when all the measured components are added up.
