Researchers think belly fat is distinct from other types of fat — like the stuff under your skin or around your arms or thighs, which doesn't necessarily have negative effects on health — because belly fat could be a sign that you have more visceral fat. That's a type of fat that accumulates around internal organs, impairing their functions and raising stress levels.
As you get older, your body changes how it gains and loses weight. Both men and women experience a declining metabolic rate, or the number of calories the body needs to function normally. On top of that, women have to deal with menopause. "If women gain weight after menopause, it's more likely to be in their bellies," says Michael Jensen, MD, professor of medicine in the Mayo Clinic's endocrinology division. In menopause, production of the hormones estrogen and progesterone slows down. Meanwhile, testosterone levels also start to drop, but at a slower rate. This shift in hormones causes women to hold onto weight in their bellies. The good news: you can fight this process. Read on.
You know not to crush half a pizza before jumping in bed, but even munching on something healthy-ish at night can throw off your calorie-burning momentum. Ideally, while you're sleeping, you want your body to burn its current fat storages (read: that pesky middle-jiggle) for fuel as opposed to whatever you ate as a midnight snack. Make sure to fill up at dinner every night, and then banish yourself from the kitchen at least two hours before bed.
There's one thing to like about visceral fat: It yields fairly easily to aerobic exercise. Running, biking, or swimming—basically anything that gets your heart rate up—wins over resistance training when it comes to getting rid of the stuff. A recent study from Duke University found that jogging the equivalent of 12 miles a week is enough to melt belly fat.
"Inadequate intake of calories, especially protein, causes the body to breakdown muscle tissue to meet the needs for amino acids," says Cederquist. "I have my patients focus on obtaining adequate lean protein and spreading it throughout the day." Her recommendation: focus on 100 grams per day, which breaks down into three to four ounces of protein at breakfast, lunch, and dinner, and a few ounces for snacks.
Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time. Berries are loaded with antioxidants, which can help reduce inflammation throughout the body, and research from the University of Michigan reveals that rats given a berry-rich diet shaved off a significant proportion of their belly fat when compared to a control group. Berries like strawberries, raspberries, blueberries, and blackberries are also loaded with resveratrol, an antioxidant pigment that has been linked to reductions in belly fat and a reduced risk of dementia, to boot.
