    Along the intestinal freeway, the parking garage that is your omentum -- which is located next to your stomach and serves as your primary storage facility of fat -- looks like a stocking draped over a hanger (the stomach is the hanger), but changes depending on how much fat you're storing.

    In a person with little omentum fat, your stomach looks as if it has nylons hanging off it—thin, permeable, with some webbing. But in a person with a lot of omentum fat, the hanger looks as if snow pants are hanging on it—the fat globules are so fat that there's no netting or webbing whatsoever. So the omentum hangs underneath the muscles in your stomach, which is why some men with beer guts have hard-as-keg bellies—their fat is underneath the muscle. (Note: while cells can convert to fat in the liver, getting fatter is more of a case of your existing cells growing. When you add body fat, you don't get more fat cells, just more fat in each cell.)

    Whether it's called a beer belly, a spare tire, the apple shape, or the middle-age spread, abdominal obesity is the shape of risk. Abdominal obesity is a health hazard, increasing the risk of heart attack, stroke, diabetes, erectile dysfunction, and other woes. Risk begins to mount at a waist size above 37 inches for men, and a measurement above 40 inches would put you in the danger zone. For women, the corresponding waist sizes are 31 1/2 and 35 inches, respectively.

    Despite the name, beer is not specifically responsible for the beer belly. Research from the beer-loving Czech Republic tells the tale. In a study of nearly 2,000 adults, beer consumption was not related to girth.

    If it's not beer, what is to blame? The culprit is calories; if you take in more calories with food and drink than you burn up with exercise, you'll store the excess energy in fat cells. And unfortunately for men, their abdominal fat cells seem to enlarge more readily than the abdominal fat cells in women.

    But although beer is not a special problem, it can add to abdominal obesity by contributing calories. In round numbers, a standard 12-ounce beer contains about 150 calories; a light beer, about 110 calories. For comparison, a 5.5-ounce glass of wine or a 1.5-ounce shot of hard liquor provides about 100 calories. Since all these beverages contain approximately the same amount of alcohol, you can see that regular beer does have extra calories—unless you count the mixers and olives.
