A new meta-analysis by researchers in the UK and published in the November 2012 issue of Diabetologia found a strong relationship between sitting and diabetes. Prolonged sitting was also shown to increase the risk for cardiovascular disease and all-cause mortality, but the relationship was most robust with diabetes. It is not enough to just get in your 30 minutes of exercise a day. Continued sitting throughout the day appears to have an effect on how our bodies metabolize glucose. We are not using our muscles enough to use the glucose in our system. The pancreas secretes more insulin, and the cells start becoming insulin resistant. Health problems arise both from high glucose levels and from high insulin levels.
Another aspect of all of this is that people who sit after eating have a 24% higher glucose level than people who walk very slowly after a meal. This is certainly something to think about after Thanksgiving!
