Health Tips - About Body Fat
Human body is made up of, amongst other things, a percentage of fat. Body fat is vital for a healthy,
functioning body, protects vital organs, helps regulate body temperature, stores vitamins and helps the
body sustain itself when food is scarce. However, too much body fat or indeed too little body fat will dam-
age to your health. It is difficult to gauge how much body fat we have in our bodies simply by looking at
ourselves in the mirror.
This is why it is important to measure and monitor your body fat percentage. Body fat percentage gives
you a better measure of fitness than weight alone–the composition of your weight loss could mean you
are losing muscle mass rather than fat-you could still have a high percentage of fat even when a scale
indicates 'normal weight'.
The table as follows may be used as a guide:

Health Tips - About Body Water
Body water is the single most important component of body weight. It represents over half of your total
weight and almost two thirds of your lean body mass (predominantly muscle). Water performs a number
of important roles in the body:
All the cells in the body, whether in the skin, glands, muscles, brain or anywhere else, can only function
properly if they have enough water. Water also plays a vital part in regulating the body's temperature
balance, particularly through perspiration.
The combination of your weight and fat measurement could appear to be 'normal' but your body hydra-
tion level could be insufficient for healthy living.
