Keep on Moving!

The next time you are stuck sitting in one place for a very long time, get up and move. Sitting for extended periods markedly increases your chances of suffering a heart attack or diabetes, and dying prematurely, whether or not you exercise regularly (Medicine & Science in Sports & Exercise, May 2009). This comes from the Canada Fitness Survey that evaluated men and women for "sitting time" in 1981 and followed them for more than 12 years.

We have to explain why sitting increases risk for heart attacks and diabetes, even if you exercise. More than 80 percent of diabetics die of heart disease and diabetes can be caused by repeated high rises in blood sugar and fat after meals. When blood sugar rises too high, sugar sticks to the surface of cell membranes. Once there, sugar can never detach and is eventually converted by a series of chemical reactions to sorbitol which
destroys the cell to cause blindness, deafness, heart attacks, strokes, kidney failure, impotence and all the horrible side effects of diabetes. The most efficient way to prevent these high rises in blood sugar is to contract your muscles. Contracting muscles draw sugar so rapidly from the bloodstream that they can prevent this high rise in blood sugar. This effect lasts during active exercise, is maximal for up to a half hour after you stop exercising and then gradually tapers off in about 17 hours.

Now we know that you should keep moving for most of your waking hours. Exercise every day, and when you are not exercising, continue to use your muscles. If your job or hobbies require you to sit, get in the habit of walking around several times an hour. Avoid being overweight, and reduce your intake of foods that cause a high rise in blood sugar when you are not exercising. The foods that cause the highest rises in blood sugar are sugars in liquid form and foods made from flour.
