Body water
60% of an adult's body is made up of water. This varies according to certain
factors: older people have a lower water level than younger people, and men
have a higher water level than women. The difference between men and women
is based on women's higher body fat mass. As the majority of the body water is
found in the fat-free mass (73% of the fat-free mass is water) and the water
content of fat tissue is naturally very low (around 10% of fat tissue is water), when
the body fat ratio is low the body water ratio falls automatically.
A 5% loss of water can reduce body energy by 20–30%. Drink at least 2 litres of
liquid every day.
Normal percentage of body water:

In general sports people have 5 % more body water.
As age increases the water ratio falls by around 10 %.
