According to this article issued today by the Telegraph, read this and go for a walk :
Every extra hour a day spent sitting down could increase the risk of developing diabetes by a fifth, new research suggests.
The study found that people with type 2 diabetes spent more of their day sitting down than those without the disease.
Those with diabetes spent an average of 26 minutes longer each day in a sedentary position – such as sitting at a computer – than those with a normal glucose metabolism.
Overall, an extra hour of sedentary time was associated with an 22 per cent increased chance of type 2 diabetes.
However, the research did not prove that couch potato lifestyles caused the extra risk of the condition. It could be that those with diabetes tended to be less active.
More than 2,400 took took part in the Dutch study, which saw each of them wear an accelerometer – measuring their movement – 24 hours a day for eight days.
