Tight deadlines, bills, your kids—whatever your source of stress, having too much of it may make it harder for you to drop unwanted pounds, especially from your middle. And it's not just because you tend to reach for high-fat, high-calorie fare when you're stressed, though that's part of it. It's also due to the stress hormone cortisol, which may increase the amount of fat your body clings to and enlarge your fat cells. Higher levels of cortisol have been linked to more visceral fat.
Our increasingly slothful lifestyles are partly to blame for skyrocketing obesity rates, so it’s no surprise that being more active is a simple fix for belly fat. In 2003, a first-of-its-kind study from Duke University showed that sedentary adults accumulated abdominal fat surprisingly quickly — and that sedentary women stacked on fat more visceral fat than sedentary men, even though they added less fat overall.
Which means, sadly, the more glasses of rose and chocolate-coated pretzels you eat, the longer it will take to reach your flatter belly goals. “When you digest large amounts of calories, your body allocates some of these to functional systems which work to keep you alive (think the brain, muscles and organs),” says Belalij. “It also uses it to fill up energy stores. Any excess is then stored in fat cells around the body – typically being those of the belly.”
