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 damage 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’.
