Being a slob puts you at risk of mental health problems, experts have warned.
A lack of physical activity leads to depression and dementia, evidence presented at the British Nutrition Foundation conference shows. It comes as new research from the University of Bristol found that being active cuts the risk of Alzheimer's disease by around a third.
Currently only 35% of men and 24% of women reach the recommended weekly amount of physical activity.
Professor Nanette Mutrie, an expert in exercise and sport psychology at the University of Strathclyde, told the conference that mental health was not a trivial issue. "It's only recently that people have begun to see the link between physical activity and mental health.
"It's important for increasing people's self esteem, general mood, coping with stress and even sleeping better. And we now have very strong evidence that physical activity can prevent depression."
She said inactive people had twice the risk of becoming depressed and there was also very good evidence that exercise is a useful treatment for depression.
