A figure used to assess the % of fat in your body. Body Mass Index
BMI Body composition is the % of your body that is fat versus the % which is lean, e.g. muscles, bones, organs. BMI is a figure used by Government to try to slow down the trend of increasing obesity in the UK.

This statistic will include your children!

For example someone who weighed 68kg, and was 1.68m tall 1.68 x 1.68 = 2.82 68 divided by 2.82 = 24 The following website will calculate your BMI for you. http://www.brianmac.co.uk/idealw.htm

Lowering Your BMI The World Health Organisation recommends that all adults below 65 should accumulate 30+ mins of moderate-intensity physical activity on most, preferably all days of the week.
