A recent study that increased the daily physical activity within an office showed that workers can lose weight without losing productivity.

Changes to the office included encouraging staff to conduct walking meetings, adding desks attached to treadmills and removing chairs and traditional desk seating.

The results showed the participants’ average weight loss to be 8.8lbs, with 90% of this being fat. Those participants who wanted to lose weight lost around double this figure!
All of this and an increase in productivity over the first three months of the study!
