Rather than taking responsibility for their own weight gain, 64% of people point the finger at co-workers for bringing in too many cakes and treats, with 14% of office workers feeling under constant peer pressure to join in when goodies are passed round.
24% can't resist the unhealthy snacks brought in to celebrate birthdays and other events.
As such, on average, office workers will succumb to their first sweet snack by 10:04am and continue to pig out for the rest of the day.
Astonishingly, six in 10 British office workers admit they DO need to lose weight - but in the current working environment most only last a total of six days on a diet before cracking under pressure.
Janet Taylor, Diet and Health Manager for The Co-operative Food (http://www.co-
"The office appears to be a 'no go area' for people trying to stick to a healthier diet, with boredom levels and the temptation to snack on unhealthy foods from 'diet saboteurs' causing colleagues to pile on the pounds.
"Interestingly, those admitting they need to lose those workplace wobbly bits, say they only manage to stick to a diet or healthy eating plan for six days before caving in to the cakes, chocolates and treats brought in by colleagues."
The study shows 74% of office workers admit to consuming far more food at work than they ever would do at home, with 73% believing the sedentary nature of their job has led to them putting on weight.
A fifth of respondents eat more sweet treats at work in a bid to be more sociable, and four in 10 always go out for a pub lunch if an office colleague suggests it.
16% claim that even when they try to stop thinking about food, someone in the office will be talking about it.
As well as finding it hard to say no to colleagues, 21% of people admit that if the snacks are there in front of them, they are impossible to resist.
Chocolate is the biggest temptation for bored office workers, closely following by crisps, biscuits and cake.
Janet Taylor from The Co-operative Food continues:
"By following a few simple tips, you can turn your office environment from an unhealthy food den of despair to a fresh and healthy haven.
"Swapping a packet of biscuits for a platter of fresh fruit will help meet your five-a-day target, and having healthy alternatives, such as carrot sticks or rice cakes, close to hand will help you ward off temptation from the office 'feeders', intent on tempting you with unhealthy treats.
"If all else fails, escaping the office at lunchtime for a brisk walk will put you out of harm's way, as well as breaking up your day and burning off calories.
"There's nothing wrong with the occasional treat, but a balanced diet, with plenty of exercise, is the best way to stay in shape and ward off those office-induced pounds!"
