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 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 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.
