The devices, which cost around ?100 each, have been given to troops who risk being thrown out of the Army for failing military fitness tests to help them shape up.
One infantry unit is believed to have given every overweight soldier in the battalion one of the bracelets, which track the distance the wearer walks and calculates how many calories have been burned.
Between 2011 and 2014, more than 32,000 soldiers have failed the basic fitness test, and 60 troops have been discharged for being obese since 2002.
