Sitting down too much during leisure time increases your risk of diabetes even if you work out regularly, scientists warn.
Those
who sit very little and exercise a lot cut their risk of obesity –
strongly linked to type 2 diabetes – by up to three-quarters, a study
shows.
It
appears that long periods of inactive leisure time reduce the benefits
derived from physical exercise, say the researchers from University
College London.
This
means the best way to cut the risk of obesity – and therefore of
diabetes – is to sit down less as well as taking more exercise.
Researchers
looked at the effects of being inactive during hours away from work –
such as watching TV, sewing, or sitting at a desk – on 4,000 civil
servants over five and ten-year periods.
After
five years, those who spent less than 12 hours a week sitting and more
than four hours exercising had a quarter the obesity risk of those who
sat for more than 25 hours a week and did less than 90 minutes’ physical
activity.
