The UK's unhealthiest cities to work in

We can all find reasons why we're not as healthy as we ought to be - and for nearly three quarters of us, our job is one of those reasons.

According to the latest survey from job board CV-Library, 72.8% of workers believe that their job has had a negative effect on their health and what they eat, with more than a third saying they have gained weight as a result.

Nearly four in ten people say they eat more unhealthy food, with a further 40% saying that they snack a lot at work.

The unhappiest places in the country revealed

"Weight gain at work is not uncommon, especially for those in office jobs that require little to no physical activity throughout the day," says CV-Library founder and managing director Lee Biggins.

"But while we all need a sugar fix every now and again, balancing this with a bit of fresh air at lunchtime can really help with productivity, especially now that the sun is beginning to shine!"

And some cities are more unhealthy than others. In a few - such as Manchester, Birmingham and London - people say they've actually experienced weight loss or ate more healthy food as a result of their job.

However, while 78.4% of people overall say that their colleagues often bring unhealthy snacks to the office, this rises to 83.8% in Scotland and 80.6% in Newcastle.

The key to long life and good health? Never stop working

"While it's great to see that workers in some of the UK's core cities are experiencing a more positive result in terms of their health, it's concerning that the numbers of those eating unhealthily are higher than the former," says Biggins.

"Boredom or procrastination can often lead to too many afternoon snacks, and many of us are guilty of overdoing it when we're stressed, but your diet can have a worrying effect on the way you function and your productivity."

A recent survey revealed that an unhealthy lifestyle is often linked to money worries, with people who are in poor health or who eat unhealthily being more likely to miss bill payments, have nothing in their savings accounts and struggle to cover everyday expenses.
