It can be. A number of studies suggest that "potbelly" fat is linked to an increased risk for heart disease, diabetes and premature death.

One 10-year study of 360,000 people concluded that for every two-inch gain in waist circumference the risk of dying climbed 17%. For women with waists above 35 inches, the risk was 78% higher than women below 28 inches. For men above 40 inches, the risk was double that of men below 34 inches for heart disease. Ten long-term studies also concluded that having a big belly can more than double the risk of diabetes. The problem is excess belly fat - called "toxic fat" - which secretes a copious mix of inflammatory substances.

Here is how to test yourself. Wrap a tape measure around your bare middle at the belly button. Relax, exhale and measure the inches. Don't cinch the tape snugly. Girths greater than 35 inches for women and 40 inches for men signal high risk for diabetes and heart disease.

There is some evidence of correlation in children also. The Cleveland Clinic advises parents to talk with their doctor if by age five their child's waist size exceeds 24 inches; by age 10 if it's more than about 30 inches; or by age 15 if it's more than 35 inches.
