There’s a lot of studies going on, since the standing desk craze is still relatively new. According to Livestrong, you can burn up to 114 calories per hour. In an eight hour workday, that’s going to yield just over 900 calories burned throughout the day. As time goes on, you may burn fewer calories if you’ve built up substantial leg muscle or lost weight as a result of standing for prolonged periods of time, as opposed to sitting. Those effects may only drop as much as 10-20%, which still make standing a far better option for your health and waistline.\r
