Make sure you do something to stay physically active everyday! Barry Braun from the University of Massachusetts and co-workers have found that just one day of physical activity decreases insulin sensitivity! Insulin sensitivity defines how well your body metabolizes blood sugars. In other words the more sensitive to insulin you are, the less insulin you will produce in order to keep blood sugar stable. The take home message is: One day of physical inactivity has a negative effect on metabolic health!
