Men with a BMI between 30 and 35 had a 24 percent increased risk of death compared to normal weight men. And women with a BMI between 30 and 35 had a 17 percent increased risk of death compared to their slimmer counterparts, Pischon said.
When the researchers factored in abdominal fat, they found that men with the largest waist circumference had more than double the risk of death, and women with the largest waist circumference increased their risk of death by 78 percent.
"Having a large waist circumference is related to a higher risk of death. This is even true for people who -- in terms of BMI -- would be considered as being normal weight," Pischon said.
Dr. Marc Siegel, an internist at New York University Langone Medical Center in New York City, said, "Fat is a problem. Obesity of all kinds correlates with heart disease, stroke, diabetes, and more. But, abdominal fat is a more rudimentary indicator of risk.
"The bottom line is, if you want to live a long and healthy life, eat right, exercise and reduce stress. Fat is bad for you, period," Siegel added.
