The recession, it seems, is bad for the waistline: ten per cent of American workers reported snacking more during the day due to economic concerns, and 43 per cent said they’re gaining weight while on the job, according to a survey from online jobs site CareerBuilder.com. Of those who gained weight, fully one quarter gained more than 10 pounds; a sixth gained over 20 pounds. What’s behind it? While 39 per cent said they eat lunch out twice or more a week, 12 per cent eat lunch from a vending machine at least once a week, and two-thirds snack at least once a day—another 24 per cent snack twice a day. But just 9 per cent of employees work out at midday, despite the fact one-quarter of companies provide gym passes or facilities. “Weight gain in the office is common and is a result of a variety of issues including today’s economic stress and poor eating habits,” said Rosemary Haefner, vice president of human resources for CareerBuilder.com, Reuters reports.
