Being obese increases the chance of suffering a stroke.
There are also links between obesity and lack of exercise - those who are physically inactive have three times the risk of a stroke.
Research on middle-aged men found that moderate levels of physical activity, such as frequent walking plus a recreational activity or sporting activity once a week, had a significant benefit on their risk of heart disease and stroke.
Similarly, women who were physically active were at lower risk of stroke.
