It is news that will strike fear into the hearts of office workers everywhere.
Scientists have revealed that sitting down for long periods of time really does give you a bigger backside.
The shocking research found that the added pressure put on areas of the body used for sitting or lying down produces up to 50 per cent more fat in those isolated parts.
The findings clearly illustrate why couch potatoes and others with sedentary lifestyles pile on the pounds – especially when combined with an unhealthy diet and lack of exercise.
More disturbingly though, the study explains for the first time how even those with healthy diet and exercise habits will be affected if they spend long periods sat behind a desk.
