Exercise zaps belly fat.
It's the easiest way to beat the bulge, period. "Regular moderate- to high-intensity aerobic exercise has the greatest impact on reducing ab fat -- the dangerous fat that ups your risk of diabetes and heart disease," says Olson. Exercise is the ultimate middle manager because it lowers levels of cortisol, a hormone that has been linked to ab fat. In fact, women with the most cortisol in their system have higher BMIs and bigger bellies than those with moderate amounts of the hormone, found a University of California at San Francisco study.
