There's something about doing a 9-5 office job which seems to make you incredibly hungry. Well, not necessarily hungry, but there's definitely something about it which makes you want to eat all the time. Some say it's boredom, some say it's temptation; but whatever causes it, it's extra calories you probably don't need in your life. And according to a new survey carried out by Dutch food brand Kallø, all those extra calories add up to a whopping amount every year. 100,000 extra calories per year for the average woman, to be specific. The figure equates to roughly 50 extra days' food intake every year. Which really doesn't seem worth it when you think about it.The Sun reports the survey discovered the average woman will eat 135 cookies, 90 slices of cake, 90 packets of sweets and 45 doughnuts a year at her desk. The peak time for snacking was revealed to be 10:30am and 3:30pm, not surprising when you consider this falls perfectly into the mid-morning and the mid-afternoon lull. Fridays were found to be the day women most relaxed their healthy eating, giving into the temptation of sweet treats. That was closely followed by Monday, because who doesn't need a little pick-me-up to start the week? While we all know we shouldn't focus too much on calories — it's more important is to have a balanced diet along with regular exercise if you're trying to maintain a healthy way of life — this kind of information is a clear message that we should try to cut down on all the extra food we snack on at work. Because the chances are it's not going to be hugely nutritious, and will only end up leaving us feeling sluggish and tired (far from productive).
