Body water

About 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
a women's higher body fat mass. 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 high, the body
water ratio falls automatically. A 5% loss of water can reduce body energy by 20–30%.
Drink at least 8 cups of liquid every day.
