Percentage of Water in the Body

The human body is 68.8% of water by weight and other percentage is protein which is 16.6%, fat is 14.9% and nitrogen is 13.3%. If we take the average body weight of a man who is 70 kg the water in his body would be approximately 40 liters which comes to an average of 57 kg of his body weight and in adult women fat makes up more of the body weight as compared to men therefore 55% of their body contains water and in an infant it would be 75% of the body weight. The percentage goes down as a person is aging. There are other factors due to which the percentage of water would decrease such as obesity, age and population.
