Researchers think that women should more than double their daily exercise time in order to control their weight. Presently, we are advised to aim for 35 minutes a day of moderate exercise for health and weight control. But scientists at the University of Alabama at Birmingham now warn that this may not be enough.
They have studied a group of women who reported a tendency to gain weight. Physical inactivity alone accounted for 60 per cent of the weight gain - with food intake becoming a minor factor. But the researchers think that the current guidelines need to be increased. They suggest that 80 minutes a day might be needed, rather than 35, to make a real impact on obesity problems.
