Though we look rather solid, and feel dry to the touch, anywhere from 41% to 84% of our body weight is represented by water alone. The spread is so wide because of age, fat (adipose tissue), and protein (muscles) content. In general, a frail old person will have the lowest ratio of water content to total body weight, while newborns and infants will have the highest. For adults (19 to 50 years of age) the water content ratio ranges from 43% to 73% for men, and 41% to 60% for women. The water content decreases in overweight people, because adipose tissue contains less water (10%–40%) than does lean tissue (75%). For the same reason—more fat—women’s bodies contain less water than men’s. (Source: all figures. )
