As the home of delicacies including the deep-fried Mars Bar and Irn Bru, the Scots are not renowned for their clean living.
And it seems the country's reputation may be well deserved - with almost every inhabitant leading an unhealthy lifestyle.
A study has found 97.5 per cent of the Scottish population are either overweight, smokers, heavy drinkers, take no exercise or have a poor diet.
The scientists behind the report conclude: 'The Scottish population seems to be living dangerously.'
But the English do not fare much better - with 94 per cent having some form of poor lifestyle.
Scotland has long suffered from a reputation for ill-health and has higher death rates from cancer, heart disease and stroke than anywhere else in the UK.
This is despite Scottish health spending being up to 16 per cent higher per head than it is south of the border - giving them access to a wider range of drugs than the English. Last month the Centre for Public Policy for Regions think tank found that between £212 and £267 more per head of population was spent on health in Scotland than in England.
But although death rates from major diseases in Scotland have improved dramatically in the past decade, they are still worse than in other regions.
The study published in online journal BMC Public Health, led by Dr David Conway, from the University of Glasgow, was based on data from 6,574 people who took part in the 2003 Scottish Health Survey.
An estimated 86 per cent of Scottish men and women had at least two risk factors, 55 per cent had three or more, and nearly 20 per cent had either four or all five, the authors added.
Dr Conway said the unhealthiest Scots tended to have a poor education and live in a deprived area.
Although a separate study three years ago found that 94 per cent of English people have an unhealthy lifestyle, it only considered four risk factors meaning the true proportion could be higher.
