The Truth About Belly Fat

What's the best way to trim your tummy?

Having a flat belly or so-called "six-pack abs" is a dream of most adults. If you're middle-aged, have ever been pregnant, or sometimes indulge in too much food or one too many beers, you probably have a spare tire you'd like to get rid of. So what's the best strategy for banishing belly fat? Is it as simple as adding certain foods to your diet, or doing particular exercises?

WebMD turned to the experts for answers on belly fat -- and the best ways to lose it.

Don't despair; you can lose that spare tire, experts say. But there's no secret formula.

"There is no magic bullet, diet plan, specific food, or type of exercise that specifically targets belly fat. But the good news is belly fat is the first kind of fat you tend to lose when you lose weight," says Michael Jensen, MD, a Mayo Clinic endocrinology specialist and obesity researcher.

Whether you're an "apple" shape with excess belly fat, or a "pear" with wide hips and thighs, when you lose weight, you'll most likely lose proportionately more from the abdominal region than elsewhere.

"Ninety-nine percent of people who lose weight will lose it in the abdominal region before anywhere else -- and will lose proportionately more weight from the upper body," says Jensen, also a professor of medicine.

And why is that? "Visceral fat, the kind tucked deep inside your waistline, is more metabolically active and easier to lose than subcutaneous fat under the skin, especially if you have plenty of it," explains Penn State researcher Penny Kris-Etherton, PhD, RD.

And the more weight you have to lose, the more quickly you're likely to start losing your belly fat, experts say.

"People who are significantly overweight may see quicker results in their belly than someone who has less to lose in that area, such as a postmenopausal pouch," says Georgia State University nutrition professor, Christine Rosenbloom, PhD, RD.

A recent study in the American Journal of Clinical Nutrition showed that a calorie-controlled diet rich in whole grains trimmed extra fat from the waistline of obese subjects.

Study participants who ate all whole grains (in addition to five servings of fruits and vegetables, three servings of low-fat dairy, and two servings of lean meat, fish, or poultry) lost more weight from the abdominal area than another group that ate the same diet, but with all refined grains.

"Eating a diet rich in whole grains while reducing refined carbohydrates changes the glucose and insulin response and makes it easier to mobilize fat stores," says study researcher Penny Kris-Etherton, PhD, RD, a distinguished professor of nutritional sciences at Penn State University.

"Visceral fat is more metabolically active and easier to lose than subcutaneous fat, especially if you have plenty of it and the right conditions are met, such as the ones in our study."
