Sitting for too long is not for you my friend


You might want to stand up while you read this, especially when you find out what some scientists have discovered about sitting.

We all know that sitting can contribute to weight problems and common sense tells us that's because sitting doesn't burn as many calories as, say, standing or walking. But, that isn't the only issue with sitting.

In a study published in Diabetes, scientists found that when we sit for long periods of time, the enzymes responsible for burning fat actually shut down. Not only that, but sitting too much can also lower HDL ('good' cholesterol) and lead to a slower metabolism. Even if you exercise later in the day, that won't necessarily undo the damage done by sitting.

The question these scientists are asking, and maybe the question some of us are wondering is: "Can the average adult who already does not follow the public health policy prescribing regular moderate-vigorous exercise become even more unhealthy in the coming years if they sit too much and do not maintain sufficient daily nonexercise physical activity?"

The answer to that is probably a yes, unless we do something about it. The good news is that just standing up can kick your fat-burning enzymes into gear.

Take a walk for 5 minutes after every hour in your workplace. Fall in love with the stairs in your building. Walk up to the colleague instead of calling/messaging. Pursue your favorite sport. Go dancing; do anything but sitting all day long.
