Do you sit most of the day? A small, randomized crossover study has found that sendentary, non-diabetic, overweight volunteers significantly improved serum glucose and insulin responses to meals when they interrupted their sitting every 20 minutes with 2 minutes of light or moderate walking activity. More research is needed to determine the long-term benefits of brief interruptions to prolonged sitting, but there are probably no downsides!
PositiveTip: Get up and move around as much as possible during the day–even briefly!
