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.

Routinely squeaking by on five hours or less per night increases visceral fat levels, according to a 2010 Wake Forest University study. What’s more, after analyzing 28 different studies, UK researchers found that people who slept 5.5 hours or less per night ate an extra 385 calories the day after compared to those who snoozed for at least 7 to 12 hours. On top of that, they preferred to munch on fatty foods full of empty calories, like chips.

Belalij suggests doing 30-minute sessions, three times per week. “As you start to lose belly fat your body will want to cling on more and more to what is left, so you must increase the intensity or duration of your workouts, the more fat you lose,” Belalij says. And Hughes agrees:
