In recent decades, scientists around the world have debunked the idea that fat cells are passive bags of calories. In addition to their storage function, mature fat cells are now known to send and receive many hormonal signals that help regulate metabolism
Sitting makes you fat
When you park your butt in a chair, your metabolism comes to a screeching halt. It's all because of an enzyme called lipoprotein lipase, which resides in the blood vessels of your muscles. "Lipoprotein lipase captures fat in the blood and incinerates it," says Hamilton. When you're standing, the postural muscles that support your weight, mostly in your legs, release the enzyme, which goes to work burning fat. But when you're sitting still, and not shifting every 30 to 90 seconds as the body does naturally, "the fat stays in the arteries, and can be stored in adipose tissue?also known as body fat," Hamilton explains.
A typical day of sitting lowers lipoprotein lipase activity by 90 to 95% (in animals), which is why when Hamilton takes blood samples of his human subjects while they're sitting and eating, the plasma?ideally clear?is white and chunky, filled with fat, the sign of a sluggish metabolism.
Worse yet, experts say that 60 to 90 minutes of daily exercise may not counteract the effects of sitting all day
Poor fat burning. The walls of your capillaries are lined with lipoprotein lipase, an enzyme that breaks down certain fats in the bloodstream. Sit for a few hours, and these enzymes start switching off. Sit all day, and their activity drops by 50%.
