Receptionists and administrative workers are most at risk of gaining weight while working, according to a new study.
More than 40% of US workers have gained weight since starting their jobs, according to new research by online job site CareerBuilder.
Of those who reported a weight gain, 59% put on more than 10 pounds – about 4.5kg - and 30% gained over 20 pounds.
Workers in sedentary roles, such as receptionists, are most likely to gain weight, the study found - 69% said they had put on weight since starting their new role.
Scientists put on least weight
Sitting at desks for long periods, over-eating due to stress and consuming readily-available junk food were all reported by workers as reasons for putting on weight.
Meanwhile, scientists put on the least weight with 39% likely to report a weight gain while at work.
Alongside them were factory workers and machine operators - 45% put on weight since starting their current job.
Nurses, teachers, IT managers and legal professionals fell into the middle category with all of them reporting roughly a 50% likelihood of excess weight gain.
Workers not exercising enough
The research found that many people did not exercise on a regular basis and one in 10 did no exercise at all.
Only 8% of workers did any exercise during their lunch break.
Rosemary Haefnar at CareerBuilder says: "Weight gain at work often comes from a combination of poor eating habits when you’re on the go and not being able to fit a workout into a busy schedule."
Haefnar advises workers to incorporate exercise into their daily routine, for example, getting off the bus or train at an earlier stop and walking the remaining distance.
"Also drinking water not only makes you feel full, it can also help cut down on calories from sugary drinks," she says.
Two-thirds of England obese
According to the NHS, most people in England are overweight or obese.
Statistics show that just under two-thirds of adults and just under a third of children age two to 15 are obese or overweight.
It is estimated that the health problems derived from obesity cost the NHS more than £5billion every year.
Initiatives such as the Change4Life programme have been launched to combat the rising epidemic of obesity in the UK and improvements on food labelling and physical activity guides are two of their main campaigns.
