Can short exercise "snacks" help reduce blood insulin levels?

We’re talking exercise, not food. In a recent study, when 11 adults with overweight or obesity spent 9 hours taking an hourly stair-climbing “snack”—which meant briskly climbing 55 steps—their blood insulin levels were 17 percent lower than when they spent 9 hours sitting. Each “snack” took 20 to 60 seconds.
