London, Dec 27 (ANI): An Oxford University study has found that the average man in Britain was more than a stone heavier in 2000 than he was in 1986.
Scientists put the average weight rise of 7.7kg down to men eating more calories and taking less physical exercise than 15 years earlier, reports the BBC.
The British Heart Foundation research in the British Journal of Nutrition analyzed changes in food consumption and body weight between 1986 and 2000.
Women's average weight gain over the period was 5.4kg.
By studying official figures on body weight from 1986 and 2000 and calculating the food energy available during that time, researchers were able to work out the expected extra food eaten by men and women during that period.
They predicted that the average man in 2000 ate more food than the average man in 1986 - enough to make him 4.7kg heavier in weight.
But the actual observed increase in average male weight turned out to be higher. (ANI)
