Taking a short walk, even for as little as two minutes, can greatly reduce your blood sugar after a meal. In a new study published in the journal Sports Medicine, researchers in Ireland compiled the data from seven studies that compared the effects of sitting, standing or walking. They found that just a few minutes of light-intensity walking after a meal were enough to significantly improve blood sugar levels compared to sitting on the couch watching TV or working at your computer at the office. Even just standing for a few minutes was better than sitting. The optimal time to walk is within 60 to 90 minutes of eating. If you can’t walk near home or at work, then find some other way to be physically active, like doing housework.
