Men have a higher percentage of water in their bodies than women. The bodies of an adult males average about 60 to 65 percent water, and adult females average about 55 to 60 percent. Those averages are affected by the amount of fat tissue carried — fat will not hold as much water as muscle tissue. This means that the body of an adult male who has low body fat and a reasonable amount of muscle mass will contain more water than a male who has low muscle mass and a greater amount of body fat.
