The Armed Forces Weight Management Policy, 2009DIN01-181, which came into force on 01 October 2009, provides the policy for the measurement of body composition and the management of Service personnel who demonstrate increased risk of ill health and inadequate physical fitness owing to their weight.
The policy requires each Service to provide annual body composition measurement (BCM) for all personnel, in order to identify an individual’s level of health risk and encourage maintenance of a healthy body weight.
