Inactivity 'kills more than obesity'

A lack of exercise could be killing twice as many people as obesity, a 12-year study of more than 300,000 people suggests.

They concluded that getting everyone to do at least 20 minutes of brisk walking a day would have substantial benefits.

Experts said exercise was beneficial for people of any weight.
