The key to losing belly fat with exercise, though, is making sure your sweat session is intense. You’ll want to be working at 85% of your max heart rate at least, says Olson. “The higher your heart rate, the higher the release of epinephrine into the bloodstream and cells,” she explains. “A positive side effect of epinephrine is that it also activates greater release of abdominal fat into the bloodstream to be used for energy.”
In a way, moderate-intensity physical activity is that "magic pill" a lot of people are looking for, because the health benefits go beyond keeping your waistline trim: Not only can it reduce your risk of cancer, stroke, diabetes and heart attacks, but studies have shown that physical activity can significantly improve the moods of patients with major depressive disorders.
