Human Body Composition by Mass
Key Findings
About This Dataset
Human Body Composition by MassWater dominates the body's mass at roughly 60%, more than the combined total of every other component - a single reason dehydration is so quickly dangerous. Protein and fat follow, each around 16% in a lean adult, though fat is the most variable component between individuals and can rise well above this in people with higher body-fat percentages. Minerals, concentrated in the bones and teeth as calcium and phosphate, make up about 6%, while carbohydrates account for barely 1% because the body stores very little sugar at any moment. The breakdown highlights that, chemically, a human is essentially water plus a modest scaffold of protein, fat and mineral - with carbohydrate present only in transit as fuel.
